2015/07/17 (F) A High Pressure Situation

Leave a reply

We closed up the house yesterday and turned on the air-conditioning as the forecast for today was upper 80’s with humidity to match and the forecast for tomorrow is a high of 90 with very high humidity.  Linda did not sleep well again last night but that had nothing to do with the air-conditioning.  The sites where the dermatologist had removed things itched, which did not help.  Nonetheless, we were both up by 8 AM and, as usual, I made coffee and we had granola.  I prepared a travel mug of coffee and left at 9 AM for Chuck’s bus garage in Novi.  Brendan, Shawna, and Madeline were due to arrive at 10 AM and I wanted to be back as close to that time as possible.

As I was working on the design for the pull-out pantry yesterday it became very clear that I needed more accurate measurements of various details of the new refrigerator in order to make sure the doors could open and the pantry could slide in and out.  It was a good thing that I checked as the measurements were not exactly as published and the specifications did not show exactly where the doors were hinged or how much clearance they needed to swing on the hinges.  Now I know, and it is a bit more than I originally allowed for, so it was a good thing that I checked.

I got home at 10:15 AM and the trio was already there.  Mara emerged from her rig a few minutes later and joined us.  Brendan and Shawna stuck around for a while but not long enough to get Madeline down for her 1 PM nap.  They had been talking to her all week about staying with Grandma Linda and Grandpa Bruce and she was prepared.  She was busy playing with Linda and did not seem concerned when her parents left for a music festival in Chicago.  They will retrieve her on Monday.

Our older grand-daughter (and Madeline’s cousin), Katie, arrived around noon so Madeline had one of her buddies here.  Madeline enjoyed her lunch and voluntarily laid down for her nap.  Katie signed up to sell Cutco cutlery and accessory products and asked if she could come practice her sales pitch on us.  We had agreed to let her do this, of course, and Mara joined us by her own choice.  The selling involved a lot of demonstration and use of a few of the knives in side-by-comparison with our existing knives, some of which were already Cutco brand.  Linda ordered a pair of kitchen shears and a santoku trimmer knife.  Mara also ordered a pair of shears and Katie was able to throw in a birdsbeak paring knife which Mara will get as Linda has one.  They agreed to just split the cost of the total order in half.

Mara was anxious to work on the roof of her Bounder and it needed to be cleaned before it was caulked.  It was a hot, humid afternoon and pressure washing the roof seemed like the perfect use of such an otherwise miserable day.  I got out the pressure washer and hose and got it hooked up.  Mara put on her bathing suit and we both climbed up on the roof of her motorhome.  I adjusted the spray nozzle to a fan pattern that would clean from 12″ away without damaging anything, showed her how I would approach the job, and left her to do the work.  Actually I sat in the shade on the porch, offered helpful advice, and occasionally moved the pressure washer.

Madeline finished her nap while we were working and came outside several times with Linda to see what we were doing.  She and Linda walked around the back yard and saw geese and a snake.  They also saw a young deer from our bedroom doorwall.  Our home in the country is a different and exciting place for her as it is for us.

When Mara was done spraying off the roof I sprayed off the sides of the rig to rinse off the dirty water that had run down the sides.  Mara then put out the patio awning and I sprayed off both sides of it as well.  When we were done we got the hose off of the grass and put the pressure washer back in the garage.  Mara was very pleased with what she accomplished.  Not only did she get something done that needed to be done but it was another thing she took care of herself instead of paying someone else to do it.  I get that.

I worked some more in my office and then came upstairs for dinner.  Mike (W8XH) had called and confirmed that Steve (N8AR) was expecting us at 8 PM.  I left at 7:30 PM and drove to Steve’s place southwest of Howell.  Mike and I arrived within a couple minutes of one another and were there for a little over an hour.

Steve is a PhD electrical engineer who worked for Bendix and was involved in communications projects for space programs.  He has a lot of test equipment that you will not find in most ham shacks and he knows how to use it.  In this particular case he used his Hewlett-Packard Network Analyzer to do two-port radio frequency through-measurements of my two Morgan Manufacturing lightning arrestors.

The first thing Steve noticed was that the center contact on one of the N-female connectors was spread open a bit.  Unfortunately any spread is “a bit” too much.  At radio frequencies these contacts need to be tight.  We crimped the contacts back together as best we could so we could proceed with the testing, but Steve strongly suggested that I replace them with high quality parts.  As expected, based on my operating experience, the M-302N V/U arrestor did not look good when tested.  Steve captured the resulting return loss graph and put it on a thumb drive for me.  I will e-mail it to Morgan with a cc: to KF7P Metalwerks and request a new one.  If the new one isn’t any better I will request a refund.  I should not have to rebuild stuff like this and the poor performance may be a design flaw rather than a manufacturing defect.

When I got home around 9:30 PM Linda and Mara were still up and chatting away in the living room.  I joined the conversation until they both decided to retire for the evening.  I spent a few minutes in my office after that taking care of e-mails and then went to bed.  I wrote for a while but was too tired to concentrate and went to sleep.

 

2015/07/06 (M) Arrested

Leave a reply

Our morning started with coffee, once we got up, and then granola for breakfast.  We are both in better health, generally, than we were in our 30s, 40s, and early 50s, but having Madeline here requires a different kind of constant energy and attention and we are somewhat tired by the time her parents take her home.  It’s a good tired, of course, but we were still tired this morning and slept in for a while.

I had hoped to get back to work on the bus today but the afternoon highs were forecast for the mid-80’s which would make for less than comfortable working conditions.  The forecast for the rest of the week was for highs in the 70’s so I decided to wait another day.  I really needed to get back to work on the bus but I also had other things to take care of that seemed at least as pressing.

At the top of my list was the SLAARC website.  Scott Neader had successfully copied the SLAARC WordPress website from GoDaddy.com to QTH.com and changed the domain pointers to point to the QTH servers.  He needed me to check that everything was working correctly.  He was also preparing to transfer the domain name registration and needed my involvement for that process.

Continuing with the ham radio theme, I needed to resolve how I was going to mount the new Diamond X-300NA 2m/70cm antenna and possibly remount the outside omnidirectional antenna for the cellular booster system.  That meant doing some minor engineering and possibly ordering parts.  I was also preoccupied with the fact that I was unable to participate in the SLAARC info net last night, apparently due to some malfunction in our ham radio system, and it was going to bug me until I figured it out.

Last, but not least, was the fact that I was now one month behind on uploading posts to our blog.  The farther behind I get the more of a chore it is to get caught up.  Like cleaning up my e-mail inboxes, which I also need to do, it finally becomes “the” thing I “have” to take care of before I can concentrate on any other work.  I hate it when that happens, but it is a recurring problem and I have no one to blame except myself.

I often seem to spend the first part of each morning finishing up my blog post (draft) for the previous day and outlining the one for the current day or making notes for future days.  It’s my way of reflecting on what I have done and thinking ahead to what I need/want to do next.  By the time I actually got to work this morning it was after 10 AM and Keith showed up to cut the grass.  It did not rain this past week and he was finally able to cut the grass at the west end of the property, which is low and often wet.

Before going to my office I checked the rebate paperwork which Linda had assembled for the new Yaesu ham radio and got it ready to mail.  I also started filling out the prescription form to send in to Catamaran Home Delivery when I realized the doctor had written the Rx for 30 days instead of 90.  I called the clinic and they said it would (probably) be OK to have Linda bring it to her appointment tomorrow and have the doctor rewrite it.

When I finally got to my office I looked at the SLAARC WordPress website on my computer to make sure everything was working.  The only thing that was not working was an online tool for logging check-ins for the Sunday evening info net.  I e-mailed Scott about that and then logged in as an administrator and updated several plugins.  I logged in to the FMCA-GLCC website and updated it and then did the same for our personal website.  I then created a support ticket at iPower.com regarding the broken FMCA Freethinkers website.  I dealt with SLAARC related e-mails throughout the day.

I spent the rest of the morning editing blog posts for the second half of June and early July and then started selecting and processing photos to use with blog posts, and processed those further.  By the time I quit working I had photos ready for everything except the three days of the ARRL Field Day event.

It was a nice day, if a bit warm, and we had the house opened up including the basement doorwall.  Other than a short break for lunch by 2 PM I had sat long enough and decided to setup the new Diamond X-300 2m/70cm antenna on a temporary pole.  I rummaged around the garage and found the four section pole I had used at the old house.  The pieces were buried under a pile of GLCC related PVC flag pole sections but I was able to slide them out.  I cleaned up the swaged connections and used a light coating of anti-seize compound before assembling them.  I stood it upright on the ground at the NE corner of the deck and zip tied it to the corner post at three points.  I then set up the 7-foot step ladder on the deck and removed the upper two sections.

The new Diamond X-300NA VHF/UHF ham radio antenna is visible atop the pole at the corner of the deck.

I unbolted the X-300 antenna from its storage place on the side of the 40-foot tower and set the base on the east deck railing.  I then got one of the 35-foot heliac coax cables from the basement and attached it to the feed point of the antenna.  With Linda’s assistance I mounted the antenna to the top of the topmost mast section and zip tied the coax to the mast.  Back up on the ladder I was able to slip the upper mast sections into the lower mast sections and add a couple more zip ties to secure the coax.

I routed the coax over to the cable entry box (CEB) so that it was not visible.  The antenna is shielded from view by our Norway Crimson King Maple tree and the mast is very inconspicuous; not bad for a temporary installation.  I disconnected the X-50 antenna coax from the Morgan UHF/VHF Lightning Arrestor in the CEB and attached the coax from the X-300 in its place.  I went back to the ham shack, turned on the Yaesu radio, and listened.  Nothing.  I tried calling the South Lyon 2m repeater but nothing came back.  I tied the Novi 440 MHz repeater…nothing.  I turned the radio off and moved the coax to our Icom IC-7000 radio and repeated the tests.  Same results.  Something was clearly wrong so I called Mike (W8XH) to see if he could help me figure it out.

Mike was out but on his way back home and called me when he was back at his base station.  We verified the transmit and receive squelch settings on my radios and then tested both antennas on both radios.  Using our cell phones we confirmed that he was not hearing my transmissions and I was not hearing his, either direct (simplex) or through the repeaters.  It was now clear that RF signals were not making it into or out of my system and there was one component that was common to all configurations; the Morgan M-302N VHF/UHF Lightning Arrestor.

I have a coaxial cable adapter kit that allows me to temporarily interconnect most of the connectors used in amateur radio coaxial cables.  At Mike’s suggestion I used the kit to assemble an adapter (barrel connector) with N-female connections on both ends.  I then disconnected the antenna and radio coaxial cables from the lightning arrestor and connected the radio coax directly to the X-300 antenna coax.  Back in the ham shack I tested this configuration with both radios on both repeaters.  I was receiving both repeaters with S7 to S9 signal strength, which is good, and very little noise, which is also good.  Mike reported that my signal was very strong into both repeaters and that he was receiving me full-quieting.  I shut the radios off and then switched the connection in the cable entry box to the X-50 antenna.  We repeated the tests with the same results, confirming that the problem as the lightning arrestor and only the lightning arrestor.

Although I was disappointed that the M-302N was defective I was overjoyed, or at least relieved, that everything else was working perfectly.  Although the new X-300 antenna turned out not to be “necessary” having it on a mast above the tower will give us an even better transmit and receive capability than the current X-50 installation.  I even have some hope of being able to reach repeaters farther away in the Detroit metro area as well as in the Lansing, Flint, Ann Arbor, and Ypsilanti areas, and perhaps much farther beyond.  Windsor (Canada) and Kalamazoo are possible when atmospheric conditions are right for longer range propagation, and the Saginaw, Mt. Pleasant, Fort Wayne (Indiana), and even Cleveland (Ohio) areas are not out of the question.  Once, at the old house, I was on the Spirit of 76 repeater atop the Renaissance Center in Detroit when it picked up a 2m station from Iowa.

Relieved of my concerns, especially about the operation of our new radio, I returned to my computer-based tasks.  The first thing I did was e-mail Chris Perri at KF7P Metalwerks regarding the lightning arrestor, which I purchased from him as part of the cable entry box.  He apparently forwarded my e-mail to Morgan Manufacturing Inc., or at least e-mailed them, as I got an e-mail from Bob at Morgan with instructions on where to return the unit.  It has a lifetime warranty and he indicated they would repair or replace it as needed.

I spent the rest of the afternoon and evening, except for dinner, working on photos.  Dinner was chickpea salad on a bed of greens with steamed baby bok choy dressed in rice vinegar.  It was a perfect meal for a warm summer evening.

The humidity had been up all day and rose as the temperatures dropped at sunset, although they did not drop much.  Linda was watching an episode of Scorpion when I finally came upstairs.  We watched an episode of NCIS Los Angeles after that and then an episode of Two and a Half Men, which I have always enjoyed.  We turned on a small fan but it was a warm, uncomfortable evening for sleeping.  For whatever reason we did not turn on the air-conditioner although in hindsight we should have.

 

2015/06/19 (F) Roof Box

Leave a reply

The Apex roofers were back again this morning just before 8 AM and we were up and ready for them.  I made coffee but we deferred breakfast until after we settled the bill with owner Pat Davidson.  By 9 AM he knew what the added costs were over and above the base quote.  The major one was the 32 sheets of plywood they used to repair/replace bad areas of the roof deck.  He left around 10 AM and took half the crew with him to start another job.  The other four guys stayed behind and finished roofing the garage and cleaning up the job site.  The job was pretty much wrapped up by noon.  Sergio (the foreman) did the final walk-around and cleanup and left around 1 PM.  There is very little evidence that they had been here except for an attractive new roof and two skylights in the living room that light up the space in a nice way.

I spent the morning inventorying coaxial cables.  We have quite an assortment of 50 and 75 ohm cables in lengths from 1 to 100 feet.  I need to have all the necessary cables on hand when I climb the tower next week to remove and install antennas.  If we already had appropriate cables I wanted to use those instead of buying new ones.

The custom cable entry box from Chris at KF7P Metalwerks arrived today.  I opened it after lunch, which consisted of fresh apples and leftover black beans and rice.  We both agreed that the beans and rice dish was even better than when it was fresh.  We unpacked all of the parts that were stored inside the cable entry box and checked them off against the spreadsheet I used to order them.  Everything was there but I was initially concerned because the box was turned 90 degrees from what I ordered.  I specified a 16″ wide by 20″ tall box but got a 20″ wide by 16″ tall instead.  I suspect that Chris buys the boxes with the door/hinge already attached but it would have been nice to know that ahead of time.

We took the box outside and held it in place to see if it would be usable.  The lower left corner will hang down in front of the basement window in the sump pump room but that will be OK.  The horizontal orientation of the box will actually make it easier to get coaxial cables through the access holes in the bottom.

There were two a Morgan Lightning arrestors mounted on the copper back plane for amateur radio use; one for HF and one for VHF/UHF.  The UHF arrestor was upside down so I unscrewed it, rotated it 180 degrees, and screwed it back down.  The box also had a Morgan M-348 lightning arrestor.  I ordered an M-348B, which is the 12-wire version, but the installed arrestor had 12 terminals on top (3 strips of 4 each) plus one on each side.  There were no instructions, however, on how to wire it up so I sent Chris an e-mail regarding the anomalies and missing information.

While I was working on that e-mail, and a couple from Josh at Coach Supply Direct, we got a call from Curtis Coleman of RVillage.  The development team had launched some new features and he wanted to walk me through them.  He had just been to Prevost in Nashville for some repairs on his tag axle brakes and was headed back to Cleveland, Ohio.  He thought he might be headed in our general direction after that.

I spent some time thinking about how to mount the cable entry box on the east wall of the house which is sided in a shiplap fashion, i.e., the horizontal siding boards are angled (not plumb) and overlapped.  I needed a hole saw and arbor for my 1/2″ drill to drill the holes for the two 2″ conduits that will pass from the box through the bond into the sump pump room in the basement.  I probably already have one but I cannot get to most of the stuff in the garage and can’t afford to delay getting this box mounted; there are too many other things that need to get done that require this box to be in place first.

I was suffering from a decided lack of patience which is not the proper frame of mind for working on scale drawings of custom furniture so I went to Lowe’s to get a hole saw.  The fitting measured 2-3/4″ OD and I decided to get a 3″ hole saw just to make sure the hole would be big enough.  While I was at the store I considered how I might use different materials to mount the box.  I ended up buying a 36″ length of 1″ square aluminum tube and some stainless steel lag screws, bolts, washers, and Nylok nuts. My plan was to cut the tube into two 18″ pieces and use them in a vertical orientation between the box and the house.  They would span multiple boards, creating a plumb mounting surface, and provide support for the lower left corner which would otherwise be unsupported.

When I got back to the house I took the tube out to see how it would work.  The idea was a good one but the 18″ lengths would be too short.  I bought the only piece of 1″ tube that Lowe’s had so I knew I would have to find another one somewhere else.  Linda suggested that we try the Lowe’s in New Hudson after breakfast tomorrow but I was still feeling impatient about the whole thing.

I had a long chat with Michele Henry from Phoenix Paint.  I then relaxed with a small glass of Moscato, a nice pre-meal wine, while Linda prepared a wonderful dish for dinner of roasted red potatoes with onions, garlic, rosemary, and power greens.  It was a simple dish but so delicious and hearty.

The meal concluded and the table cleared I went to The Home Depot in Howell where I found a 48″ length of 1″ square aluminum tube.  If 24 inches turns out to be long enough to support the box the way I want I will cut the 48″ piece in half and return the 36″ piece to Lowe’s.  I called Chuck on the drive home to follow up on a text message I sent him yesterday regarding the delivery of our new refrigerator to his bus garage in Novi.

Feeling like I had finally accomplished something today we relaxed for an hour and then settled in to watch a movie.  Linda had borrowed the DVD of Wild, starring Reese Witherspoon, from the Howell Library earlier in the week and we reserved this evening as movie night.

My goal for tomorrow is to get the cable entry box installed.  That sets the stage for climbing the tower and installing three antennas once I have the proper coax cables and some rope to temporarily guy the tower.  But those details will wait until Monday as family is coming to brunch on Sunday for Father’s Day and a belated birthday celebration for our daughter.

Ron and Mary had a long drive yesterday, and an exhausting 10 days prior to that, so they went to bed tired.  Consequently they did not get up early and I did not make coffee right away.  I was up at 7:30 AM and went to my office instead.  Chris at KF7P Metalwerks accepted my change to the cable entrance box late last night and sent me a PayPal invoice.  I paid that this morning and e-mailed him back to clarify and confirm a couple points about the box.  Once everyone was up we had coffee (us) and tea (them) on the back deck and enjoyed a beautiful early summer morning.  We eventually went back inside and had the granola for breakfast that Linda made yesterday.  So good.

After breakfast we gave them a tour of our partially disassembled motorcoach and explained what we are trying to do.  I mentioned that the motorized windshield roller shades were not winding up straight and that the driver side was binding part way up.  One of the MCD vendors at the rally last week told me to put a piece of tape on one end (lengthwise) to force the shade to not run (in that direction).  Ron, who is a retired mechanical engineer, suggested that I create a tapered roller by putting tape around the roller tube at 5 to 7 places.  The tape cannot go all the way around the roller tube because of the shade but it can go most of the way around.  Ron’s suggestion was one layer towards the outside, two layers next, then three layers and finally four layers in the center.  These tapered rollers are commonly used in industry to keep conveyor belts centered.

We had just exited the bus when a minivan that I did not recognize pulled in our driveway.  It was the electric power company meter reader.  We chatted briefly, and she was very nice but was obviously on a tight schedule.

Ron and Mary needed a duffle bag and some batteries so we drove to the Dick’s sporting goods store at US-23 and Lee Road.  They found a nice duffle bag but not the batteries so we stopped at Meijer’s on the way back to the house and they found what the needed there.  We also picked up a card for our daughter, Meghan, whose 34th birthday was today.

Back at the house we called Meghan and wished her a happy birthday via voice message.  We got a text message later saying thank you.  We also had a voice message on our home phone from Pat Davidson at Apex Roofing indicating that the shingles for our new roof would be delivered on Monday.  For lunch we had pretzels and pita chips with hummus and some grapes.  I slipped off into the small bedroom and opened the box from Cellular Solutions to make sure everything was there.  It was.

Although Ron and Mary slept well last night they were still tired and decided to take naps.  That left Linda free to go for a walk and me to work in my office.  I transferred rough drafts of blog posts from my e-mail to MS Word and then started editing them but did not have time to upload them to WordPress before we had to leave to go to dinner.

We left around 5:15 PM for La Marsa.  They were in the second of two days of their 4th year celebration for the Brighton location and everything was 34% off.  They were backed up 90 minutes for carry out orders but we got a table after only a short wait.  We had Koshary and they had kabobs.  After dinner we went for a walk around the Brighton Mill Pond where we saw two gigantic snapping turtles in the pond.  One of them almost caught a muskrat and they eventually bumped into one another and seemed to be fighting.  It was quite the show.  Snapping turtles are nothing to mess around with and the shells on these two were about 2 feet long, front to back.  Gigantic.

When we got back to the house we played 13 rounds of Mexican Train.  By the time we finished it was midnight and we all got to bed around 12:15 AM.

Same routine as yesterday; up at 7 AM, open up the house, feed the cats, clean the litter tray, start a load of laundry, make the coffee, and drink the coffee while using our iPads.

Our daughter’s 34th birthday is tomorrow but she is flying to Las Vegas today to meet up with her husband who is there on a company outing.  We will celebrate her birthday when they get back, perhaps in conjunction with Father’s Day and Linda’s birthday, which is at the end of the month.

Linda left at 9 AM for Brighton Honda to have the 12 V battery in her car checked.  The battery light came on the other day so we thought it might need to be replaced.  Around 9:20 AM I heard thunder and a short time later we had a brief, heavy downpour.  Linda called at the same time and said the battery tested OK.  The problem could be the alternator, of course, but presumably the dealer service people know that and checked for that.  If not, we will likely be back there sooner rather than later.

Linda headed on to Meijer’s to do the grocery shopping.  Today was trash pickup day so I took the trash can to the street.  After meeting with Brad from Chuck It Junk Removal the other day we decided we would rent their trailer for 5 days.  For the same price as having them physically handle 1/3 of a truck of junk (5 cu. yd.) we can get rid of a full truck of junk (15 cu. yd.) by loading it ourselves.  Deal.

I got a call from Phil Jarrell regarding my request for pricing to dig a foundation hole for a ham radio tower foundation.  It was a useful conversation in that I had not previously realized that I will need a concrete contractor in addition to the concrete supplier.  The only thing the concrete supplier will do is show up with a cement mixer truck and dump the concrete where they are instructed to.  The concrete contractor will actually place rebar, build forms, provide carts or a pumper, and get the concrete from the truck to the hole.  Phil recommended Mike Fearer of Bid-Rite Concrete as a good guy who would work with me to get this done.

I talked with Chuck about getting a key to his shop so we could have the new refrigerator delivered there and have the old one picked up without having to trouble him to be there.  He agreed and suggested that we contact the guy down the street about removing the old windshield and installing the new one as part of the refrigerator swap.

Rather than dig into our bus interior remodeling project I have used the last couple of days to finalize decisions about various products and order them.  One of the things I have wanted/needed for a while is a cable entrance box that will allow me to route transmission lines and control cables into the basement from outside.  I talked to Chris Perri, KF7P, at the Dayton Hamvention last month and decided that I liked his custom fabricated cable entry boxes.  I got his business card at the Hamvention and exchanged a couple of e-mails with him this week.  I decided this morning how I want the box initially configured and e-mailed my specs to Chris.  I would like to run the cabling for the cell phone booster through this box so I needed to get it on order.  Speaking of which, the cell phone booster system arrived today via UPS so I am feeling more comfortable that all of the stuff I am ordering will actually get delivered to our house.

Wednesday’s and Fridays are when Recycle Livingston is open and the Wednesday hours are 11 AM to 5:30 PM.  We had my car loaded up with recyclables and Linda drove over after lunch to drop them off.  When she got back she made a batch of her yummy granola and I got a couple more loads of laundry done while continuing to work at my computer.

After doing my alternate tile layout for the bus floor yesterday I decided that I liked the way it looked better than the original ad that it would not involve any more cutting than the row/column layout.  I also felt confident that I had an accurate enough tile count to go ahead and order the tiles.  I drove to the Shell station to fill my tank and then drove to Lynch Carpet in Howell.  I ordered 12 boxes of the 16″ x 16″ Armstrong Alterna Luxury Vinyl Tile in the La Plata Creme Fresh pattern, and a gallon each of the vinyl adhesive and Glacier vinyl grout.  There are 14 tiles per box (24.89 sq. ft.) for a total of 168 tiles (just under 300 sq. ft.).  The inside floor area of the bus is around 300 sq. ft. before subtracting out walls and cabinets but we will be using some of the tiles on vertical surfaces in the entry stairwell and cockpit and around the box that supports the bed platform.  My estimate is that I will have 10 extra tiles.  The guy at Lynch Carpet suggested that I use a scrap piece of tile as a spacer when installing the tiles but I may use the little plastic “X” pieces designed for this purpose.

From Lynch Carpet I drove to Lowe’s in Howell to see if they had a different portable air compressor that might be more appropriate than the 6 gallon Porter Cable we just bought.  The Porter-Cable air compressor has a maximum regulated pressure of 150 PSI but that is also the maximum tank pressure.  I will have to test it on one of the front bus tires to determine if it will get the job done and if not I will return it.

The guy at Lynch Carpet also suggested that I rent a handheld grinder from Abe’s or A-1 Rental, both in Howell.  Abe’s did not have any grinders of any kind and A-1 was closed on Wednesdays.  The gal at Abe’s suggested the tool rental service at the Howell Home Depot, so I stopped there.  They also did not have a handheld grinder but they did have a floor model concrete grinder.  It was so heavy that I doubt if we could have gotten it into the bus and it was too big to maneuver in the tight spaces where I need to work.  They did have a lighter/smaller floor stripper and I may give that a try before I resort to grinding off the thinset with an angle grinder and diamond impregnated wheel and/or a belt sander with a very aggressive belt.

Pat Davidson called from Apex Roofing while I was out so I called him back.  They will be able to start on our roof next week Monday or Tuesday and will deliver the shingles on Friday this week.  I confirmed that we wanted two of the 14″ light tunnels for the living room.  I also indicated that I had scrapped the idea of building a dormer or installing a roof hatch as I simply did not get this taken care of in time.

Linda had closed up the house and turned on the air-conditioning while I was out.  It was pulling moisture out of the air but would not bring the air temperature lower than 78 degrees.  Not good.  This will be our third summer in this house and we have not used the air-conditioning very much.  The first summer we were gone for most of June, all of July, and a few days in August.  We had the unit serviced last year and thought it was working OK but perhaps did not really use it after that.  We did install filters in the return air grills so perhaps they are restricting the airflow too much.  It is also possible that it needs refrigerant.  I will have to check our records from last year and then call TOMTEK to arrange to have it serviced again.

Linda’s brother, Ron, and his wife, Mary, arrived early this evening.  They are on their way to northwest Illinois for a week-long organized bicycle ride.  They have to be there on Saturday and will be spending the next three nights at our house.  Visits from them are usually not more than once a year but we really enjoy their company when they are here.

For dinner Linda made a nice green salad and then made whole wheat angel hair pasta with onions, garlic, and mushrooms lightly sautéed in olive oil.  Ron does not imbibe but Linda, Mary, and I had a glass (or two) of Moscato.  We moved to the deck after dinner and had fresh strawberries for dessert.  It cooled off as darkness set in and we eventually moved back inside.  The other three were in the kitchen and I was sitting on the sofa when Juniper suddenly caught a mouse in the middle of the living room, or at least that is where I noticed that she had it.  She took it downstairs and I got her to drop it in the bathroom sink but I was unable to get it into a container to take it outside and it escaped into my office.  I closed the doors but I have no doubt it can go wherever it wants in the house from there.  When I returned upstairs we chatted until 11 PM and then all turned in for the evening.
