2015/10/11 (N) Now Heat This

I guess we were tired after having Madeline at our house for 23 hours.  We slept in until after 8 AM and it was going on 9 by the time the coffee was brewed and we sat down to breakfast.  I really needed to attend to some paperwork for our FMCA Freethinkers chapter but was also eager to get deeper into the manual for the new Sony a99v camera.  I installed the PDF manual onto my laptop yesterday from the CD-ROM that came with the camera and then e-mailed it go my iPad2 so I could read it conveniently.

Jasper, our mackerel tabby male cat, allows himself to be photographed on the living room floor. You wouldn’t know it from this photo, but he is actually a very sweet animal ad a real joy to have in our household.

Other than the time, date, and date format I have not adjusted any of the default settings or experimented with the camera’s many functions.  I have taken a few photos just to make sure it works but I do not want to start generating a lot of image files until I have made decisions about basic things like folder naming conventions and “normal” shooting modes and settings.  I did, however, enable a “rule of thirds” grid on the viewfinder screen.

Linda worked on our personal accounting and then prepared the treasurer’s report for our amateur radio club meeting this evening.  I took a break from reading the camera manual to research the availability of some accessories on the B&H Photo website.

The electric cable release for my old Minolta 9000 SLR film cameras works with the a100 so it may work with the a99v too.  If not, newer remotes are available, including wireless ones that are not too expensive.  I found the angle finder but it is discontinued.  With the adjustable LCD screen in the back of the camera the angle finder isn’t really necessary but would have been a nice accessory just the same.  I am also looking for a case and/or a photographer’s vest and/or a chest harness/holder.  The a99v with the vertical grip and a telephoto lens is a substantial piece of equipment, both in size and weight, and the chest harness/holder would support that weight more comfortably and securely than a neck strap.  I found several interesting things but not exactly what I had in mind.

By the time Linda finished her accounting tasks I was dressed to work.  First up was the hydronic heating system in our bus.  I got four pieces of 2×4, each about four feet long, and two pieces of 2×12 about 16″ long.  I put a pair of 2x4s under each desk base and inserted one of the 2x12s between the 2x4s and the base.  That raised each base three inches which was enough to ensure that the heater hoses attached to the lower fitting on each heat exchanger sloped slightly downward back towards the main unit.

The hose that connects the two heat exchangers together in series is attached to the top fitting on each one.  Half way between the exchangers is a T with the bull branch pointing up.  A ball valve with a waste port is attached to the branch.  While Linda held the valve higher than anything else in the system I opened the valve and used a small funnel to slowly pour in antifreeze.  When the lines and exchangers appeared to be full I closed the valve, turned on the thermostat for that loop, and turned it up to cause the circulating pump to come on.  I let the pump run for a few minutes and then turned it off.  Again with Linda elevating the valve I opened it and added a little more antifreeze.  I ran the pump again for a few minutes and shut it off.  This time the coolant was still right at the valve so I shut it and Linda set it down.

It was now time for “the big test.”  In order to be able to see if there were any leaks, and catch any coolant if there were, we put heavy duty paper shop towels under all six of the clamped connections where the heater hose went over 3/4″ copper as well as under the soldered joints of the T and valve.  I opened the water bay on the passenger side, where the Aqua-Hot is installed, checked the coolant level in the expansion tank, and made sure the paper cup was positioned under the overflow tube.  The level of coolant in the expansion tank was just above Minimum Cold.  With everything in order I turned on the Aqua-Hot burner and then turned the front zone thermostat back on.  I also turned on the thermostats for the bathroom and bedroom zones to cause coolant to circulate through those loops.

There are quite a few gallons of antifreeze in the hydronic heating system and even on a mild day such as today (temperature just above 70 degrees F) it takes a while to heat it up to the 170 degrees required to shut off the diesel burner.  I kept checking the hoses by the fill valve and the expansion tank.  When the hoses were warm and the level of the coolant had risen 1/2″ in the expansion tank I cracked open the waste port on the fill valve.  I got a tiny, short hiss and then coolant came out so I quickly closed it.  It appeared that our method for filling the system and bleeding the air out had worked as intended, and there was no evidence of any leaks.

I left the Aqua-Hot on until it shut off on its own.  The expansion tank was near full at this point and I topped it up.  As the system cools down the coolant will contract in volume and some of the coolant in the expansion tank will be drawn back into the main chamber.  It’s important that there is more coolant in the expansion tank than the amount that will be drawn in or air will get drawn in instead.  I buttoned up the coach and turned to my next task.

I removed the chain from the new Poulan Pro 18” chain saw since I completely dulled it trying to cut through a tree root.  As long as the cover, chain, and bar were off I cleaned up the motor unit as best I could.  Oil impregnated sawdust is tenacious stuff.  I put the new chain on the bar and attached them to the motor, making sure the chain was oriented correctly.  I topped up the bar and chain oil reservoir and topped off the fuel tank.

It took several trips to get the 7′ step ladder, pole saw, compound lopping shears, hand tree saw, and chain saw back to the apple tree.  I noticed yesterday that one of the main branches coming off the trunk about 3′ above the ground was dead.  The bark was missing and the smaller limbs were brittle.  The bark looked like it might have been chewed away by deer but I wasn’t sure.  All I knew is that it was dead.

I started with the pole saw and worked from the ladder to cut off the limbs that extended far up into the tree.  Once I had those detached and pulled out of the tree I started the chainsaw and used it to cut off the larger branches as I worked my way down towards the main trunk.  I gathered all of the smaller material into a pile and then gathered the larger pieces together.  I used the largest piece as a sawbuck to support the other pieces as I de-limbed them and cut them into four foot lengths.  I then cut up a large pine tree limb that has been sitting on the ground under the apple tree for quite a while.  I used the pole saw and loppers to trim off a few other small branches and the carried all of the tools back to the garage.  It was 3 PM by the time I got everything put away.  I was done with physical work for the day so I got a much needed shower and got dressed appropriately for our meeting later.

The apple tree is still in need of serious pruning if it us to survive and bear useful fruit.  It particular it needs to be “topped.”  It is too tall overall, especially in the center, and much of the fruit is growing up there where the sunlight is good but it cannot be reached either by us or by the deer.  We have been putting deadwood in the firepit all summer and, more recently, on the disposal pile, where it goes mostly depending on what part of the yard the tree was in when it fell or got cut down.  In the case of the apple tree it occurred to me that Applewood is prized for the smoke it produces when grilling so I may stack it up, let it continue to dry, and perhaps rent a chipper next year to turn it into something useful.

We had breakfast later than usual, and skipped lunch, so we ate dinner at 4:30 PM, which was earlier than usual.  Dinner was lentil loaf, baked potato, and steamed broccoli, a simple but healthy and tasty meal.

On Friday I exchanged a few text messages with Josh at Coach Supply Direct regarding our desktop and table.  The net result was that his schedule had changed and he was not going to be able to get our desktop and table from Countertops Plus in Shipshewana, Indiana and deliver them to us for over a week, at the earliest.  He had also planned to bring some extra clips for our MCD shades and look at the wiring on the front passenger seat 6-way power base.  Those last two items were not critical but we are ready to install the desk once we have the desktop and cannot afford to wait another week and a half to get it.  I called and left a message for Ferman Miller to let him know I would be driving down tomorrow morning to pick them up.  I then worked on this post until 5:30 PM when I stopped to reinstall the antenna, radio, and GPS in my car.

We left at 5:45 PM for our monthly SLAARC meeting and shortly thereafter heard Mike (W8XH) on the South Lyon 2m repeater.  I replied to his call and we had a QSO that lasted almost all the way to our meeting site, where we arrived within a minute of one another.

We socialized with fellow club members from 6:30 PM until Harvey (AC8NO) called the business meeting to order just after 7 PM.  The club secretary was absent so I took the minutes.  The business meeting lasted less than 10 minutes and was followed by a presentation on APRS by Eric (K8ERS).  I gave Mike (W8XH) a check for the Icom IC-2820H dual band radio that has been in my car since early summer.

As I said at the beginning, I really needed to update the FMCA Freethinkers roster and financial reports and make them available this evening.  Well, sometimes things don’t happen just because they need too.  Today was just too perfect a day to waste it sitting inside at a computer and by the time we got home from our meeting I did not feel like starting this task.  I will try to make this a priority tomorrow evening, but each day is an adventure and I have to be agile in dealing with the myriad tasks that lay before me, including ones that appear unexpectedly.

 

2015/09/26 (S) A Step in the Right Direction

We missed our ham radio club breakfast last week because we were at an RV rally and we plan to be at another rally three weekends from now so in spite of all the work we still have to do on the bus we went to breakfast in South Lyon.  After breakfast we went to the Lowe’s in New Hudson, which is close to South Lyon, and bought a Porter-Cable 1/4 sheet palm sander.  The sander is small enough to get into corners but has an integral dust collection bag.  The bag can be removed for sanding in really tight spots, but it cuts down on airborne dust while sanding and reduces the amount of cleanup afterwards.  We have several other Porter-Cable power tools and I am generally pleased with them.

Back at the house we took care of a few chores and then got to work on the bus.  Linda continued working on stripping the old wallpaper behind the sofa while I pondered for a while about what to do before deciding to concentrate on rebuilding the landing at the top of the entry stairs.  This landing is where the pneumatic entry stairwell slide cover was installed.  Without all of that “stuff” in place the last step up to the landing was now too short and the step up to the copilot level was too tall.  More importantly, the step heights were all different, and would be a built in trip hazard if not corrected.

I determined that the 2.5″ wide poplar boards installed on edge with a 3/4″ thick plywood floor and a top layer of 3/16″ SurePly underlayment would match the top surface of the plywood in the driver’s area.  That would (should), in turn, allow me to install the new vinyl floor tiles so they bridge that seam.  I will have to reuse the plywood in the driver’s area, but worst case that will require using adhesive remover followed by floor patching compound and sanding before installing the tiles.

The landing was not “square” (of course) so I made and rechecked measurements several times.  I then built a four-sided frame that fit snugly and had the front board aligned with the face of the plastic riser.  I am going to tile the steps and I am not going to use underlayment so I needed these surfaces as aligned and flat as possible.  I will probably use floor patching compound, however, to fill the gaps before installing the tile.  I used screws to secure the frame to the adjacent vertical wood that forms the riser to the copilot level and to the base of the landing with angle brackets.

I needed a piece of 3/4″ plywood approximately 31-1/8″ x 27-5/8″ for the new landing as the old piece I took out was not in good shape and I did not want to reuse it.  I did not have any other 3/4″ plywood pieces that were large enough so I went to Lowe’s.  They did not have 3/4″ half sheets (4′ x 4′) but I bought some more angle brackets while I was there.  I then went to The Home Depot.  They also did not have 3/4″ half sheets, but they had full sheets of 23/32″ sanded plywood that looked like it would work and a nice panel saw with an employee available to operate it.  I waited while he built a complete set of closet shelving for a couple and engaged in some domestic counseling.  He then cut the plywood sheet into two 4′ x 4′ pieces and helped me load them into a cart.  I was able to get them into my Honda Element by myself and close the back hatches.  I had a nice QSO with Steve (N8AR) on the drive home via the South Lyon 2m amateur radio repeater.

Linda had long since finished working on the wallpaper and busied herself in the kitchen preparing collard greens Cole slaw and vegan potato salad.  It was somewhere between late afternoon and early evening but I still had enough light to work outside.  Linda was still busy cooking so I decided to go ahead and try to cut the plywood for the new landing.  Again, it was not a rectangle, i.e., an equiangular quadrilateral (four right angles and four sides with opposing sides parallel and equal in length) so getting the shape exactly right was tricky.

I determined that the right front corner, as viewed from the entry steps, was a right angle, or close enough to one to provide a known starting point.  I put the plywood on 2″x4″s on the flat in the driveway to elevate them so I could clamp a saw guide in place and provide clearance for the saw blade.  I measured the lengths of all four edges as best I could and placed the right front corner at a factory corner of one of the 4′ x 4′ pieces.  I marked the length of the right side and the front on the two factory edges.  The left side was longer than the right side and the rear side was longer than the front side so I marked arcs for the left and rear lengths and found their point of intersection.  If the right front corner was, in fact, a right angle them this had to result in the correct shape.  The key word in that last sentence is “if.”

I tried to confirm my layout by measuring the lengths of the diagonals on the plywood and on the bus but I could not get accurate measurements in the bus.  I triple-checked my measurements and layout then marked the guide lines for the setback on my circular saw; 6-5/8″ to the inside edge of the teeth on the blade.  Truth be told I initially marked the guide lines on the wrong side of the cut.  I started to adjust my guide board to the outside of the blade and then thought better of the idea.  The guide needed to be set up so that if the blade wandered off course it would cut into waste material rather than the finished piece.  I re-measured and marked the guide lines in the proper place, checked their location with my small square, checked with the saw, made minor adjustments, and finally made the first of two cuts.  I then repeated all of that and made the second cut.  When I set the piece in place in the bus it was a perfect fit.  I was so pleased that I had Linda come out to see it.  Sometimes I amaze even myself.

I like to quit on a high note so that was the end of our bus work for today.  We did not make dramatic progress but we kept moving and got things done that needed doing.  My work today involved a certain amount of pondering and on-the-fly engineering combined with careful, repeated measuring and accurate cutting.  This kind of work is never fast.

A beautiful sunset had developed, which meant it was getting dark, so I put a few things away and closed up the bus while Linda prepared our dinner.  She made a nice salad and heated a couple of Amy’s vegan (non-dairy) lasagna entrées.  A glass of Moscato was a welcome accompaniment and we enjoyed a second glass as we relaxed in the living room.  We got a Rockler catalog in the mail today so I looked through that.  If you are into woodworking it’s the adult equivalent of the Sear’s Christmas catalogs of yesteryear.

I called Butch at 10 PM.  It was 7 PM in Bouse, Arizona and I figured they would be done working for the day and probably already had their dinner.  The daytime highs there have been reaching 110 degrees F so Butch and the other RV Park employees have been starting work between 6 and 7 AM and trying to finish up by 1 PM.  He did not elaborate but said the situation the first two weeks has not been exactly what they signed up for.  He had already responded to an e-mail from Linda with more details so we let it go at that and talked about other things.  We wrapped up our conversation at 10:30 and I went to bed.  I was going to play a couple of games and then go to sleep but there was an update available for the iPad OS so I installed it.  9.0.1 was a big update and took quite a while to install.  I was very sleepy by the time it finished and turned out the lights.

 

2015/08/15 (S) Steve and Karen

As we were backing out of the driveway to go to our weekly ham radio breakfast we noticed a large mailbox sitting on the ground next to ours.  It was still attached to the upper half of its wood support structure.  The number was 593, which is not an address that occurs on our street.  We left it there and went to breakfast.

We had a mid-sized group of 15 people at our SLAARC breakfast this morning.  On the drive into breakfast we lost power to our GPS every time I transmitted on the 2m ham band.  The GPS and cellular booster worked fine all day yesterday with the new 12VDC extension splitter, but I did not use the mobile ham radio.

After breakfast we went directly to Chuck’s shop in Novi to see if we could retrieve the old refrigerator using our car.  A measuring tape quickly revealed that the fridge would not fit without removing the seats.  Even then it would be too long to close the rear gate and hatch on the Element.  At breakfast Harvey (AC8NO) offered the use of his van and labor to help move the fridge and I will probably take him up on it.

On the drive home I chatted with John (NU8M) on the South Lyon 2m repeater and we were joined by Mike (W8XH).  After John signed and dropped off Linda tried different combinations of power connections while I talked with Mike.  Based on that test the splitter appears to be the problem but we could not determine if it was a voltage drop issue or some form of RFI.

I stopped on the way home to fill the gas tank in my car.  When we got home I put the mailbox in the back of my car and we drove to the end of the street but it clearly did not come from one of our neighbor’s yards.  When we got back to the house we also noticed that there was a footprint on the side of our mailbox.  Closer inspection revealed that the post was slightly loose in the ground and the box was leaning (bent) slightly to one side.  Clearly someone had tried to kick it over (and failed) and there was a very high probability that it was the same person(s) who probably broke the other mailbox and left it on the ground next to ours.  We discussed whether we should report it to the Livingston County Sheriff Department but did not take the time right then to do so.

Linda needed to make a grocery store run and then prep the food for dinner and pick up the house.  With company coming later I did not want to get all sweaty working in the bus and garage so I worked in my office editing and uploading blog posts.  I quit around 3:30 and was writing blog posts when Steve and Karen Limkemann arrived at 4 PM.

We always have a nice visit with Steve and Karen and they are good sports about eating the vegan food that Linda prepares.  Linda made a sweet and sour collard greens cole slaw and vegan potato salad ahead of time.  She cooked corn-on-the-cob on the stovetop and heated vegan beer brats on the grill along with onions and green peppers.  Steve and Karen brought a Malbec wine which we enjoyed before, during and after the meal.  Dessert was fresh strawberries with cashew milk snickerdoodle ice cream.  Really, what’s not to like?

Steve and Karen have rented a house trailer in a trailer park near Venice, Florida for the last few winters.  I think they rented it for January, February, and March and split the time with another couple, but I may not have my facts completely straight.  The owners of the trailer are from England and decided after this last winter that they want to start using it during the winter so Steve and Karen lost the use of it.  They really liked the park and its location so they bought a trailer that was for sale and already set up.  We visited them two winters ago, but we were several hours north of them.  This coming winter we will be much closer to them while we are in Arcadia during January and February and plan to see them more often.  Venice is a very upscale place and there is an excellent vegan restaurant within easy walking distance (a mile) from their trailer park.

We talked about trying to catch the tail end of the Perseids Meteor Shower but the peak was earlier in the week, they would not be visible at our location until midnight, and then only low in the northeast sky, which is not an ideal viewing direction from our yard.  Steve and Karen had a 45 minute drive to get home and left around 10:30 PM.  By that point it had been a long but very satisfying day for us and we were straight away to bed once they were safely on their way.
