Christina has had an eye out for a piano for a while. Interestingly the standard price for used pianos is ‘free, must be able to move’. With this in mind we were shopping on ease of moving – looking at the surroundings in the listing photos to determine where it likely was (i.e. garage vs inside) was almost as important as the piano itself. The right one popped up this week, so this weekend we took the trip to pick it up. I had a particular interest in this one also since it’s a player piano. Player pianos are one of the earliest (the earliest?) wide-spread programmable automated ‘machines’; it’s fascinating to see how these were designed to be built using mostly hand-made parts and to operate without electricity.
Moving: Pianos are the archetype of things that are difficult to move. The trick, as usual, is letting the equipment/physics do the work. At the pickup side it was already in a garage; after backing up near it I jacked the tongue of the trailer up so the ramp/bed formed an even & shallow slope. I was ready with the winch at this point, but because their driveway sloped away it actually rolled onto the trailer without needing it. To unload, I backed the trailer around the back of the house to the back door and then raised it up on jack stands until it was about even with the threshold. We then put a 4×4 timber across the bottom of door frame of a nearby interior door and used this as an anchor point to winch the piano inside with ratchet straps. Once it landed on the tile floor it was easy to push around.
Rebuild: As near as we can tell from the serial number the piano seems to have been built in 1920. It was also signed inside with a 1996 date, likely associated with a rebuild. The good news is that everything seems to be in place and after sealing a few vacuum leaks it was able to play automatically; It definitely had/has room for improvement though. I was able to make it sound noticeably cleaner by dialing in the correct ‘capstan’ height on the back of the keys. The next priority is getting the keys working more consistently; several of the keys (~40) were missing felt from their front hole. The front hole felt prevents the key from wobbling side-to-side. Several keys (~20) also had cracks where the back hole goes through the key. The back hole is where the key pivots, so these cracks allowed the keys to tilt side-to-side. Felt was added to the front holes and the cracked back hole parts were glued back in place; this resolved the loose key problems. For just a few keys (3) the cracked part is missing and I’ll need to create and glue in a repair piece. Once I’m finished rebuilding the keys I can then go through and set the key level and adjust the hammer action. Along the way I’ll also be coming up with an electric vacuum pump – pumping with the pedals is a work out!
Hurricane Michael hit our area hard and took out power for almost 5 days. Luckily the small generator we already had was enough to keep the fridge running and some lights on, but not much else. The small generator is 120V only, so it also was not able to power the 240V well pump; 4 nights without running water was not fun. It’s not likely we’ll have another outage that’s this long for a while, but we have had a number of shorter outages that seem to indicate that this will be an ongoing problem – a bigger generator would be nice.
With that in mind we started looking at options; there are a number of ‘off the shelf’ options out there for whole-house standby power, but most of them are very pricey both to install and to run (propane particularly) and we couldn’t justify the cost for something that gets used so infrequently. What did seem to make some sense though was rolling the dice a surplus military generator; the prices are very low (when the condition is unknown), they’re way over-built, and are made to be repaired easily.
I bid on and won an online surplus auction for a diesel generator and picked it up outside our friendly neighborhood military base. It was a fairly easy move at ~1200lb; at pickup I just dragged it onto the trailer with a winch and to offload I tilted the trailer and winched it back down with iron pipes underneath as rollers.
To get it running I first put in new batteries (2x 12v car batteries) and troubleshot some miscellaneous electrical issues (broken connections, dirty switch contacts, etc.). From there it would crank but not run; bleeding the air out out the fuel lines fixed this and it started OK. Once running there was an erratic low frequency rattle that I traced to a bad rotor bearing on the generator head. With this bearing replaced it then ran smooth/quiet. The last issue was twitchy voltage regulation that I traced back to a dirty potentiometer; with this cleaned it held a stable 240V @ 60hz under a variety of loads. Along the way it also got an oil/filter change and a coolant flush/fill.
Altogether this was a very quick project, just a few hours to get everything sorted out. Up next will be setting aside some space for it (probably combined with a new area for trashcans and firewood) and getting it wired in with a manual transfer switch. It’s a “10KW” generator but that rating is on the very conservative side; in reality it’s closer to a 15KW or more consumer unit whose ratings are on the optimistic side. This should be enough to run the lights, TV, well, microwave, and at least one zone of HVAC.
The shop is coming along well and this weekend the bulk of the insulation was installed. Friday night we picked up R15 Roxul batts for the walls and installed in just few hours. The attic was another story though and all of Saturday and Sunday AM were spent crab walking over attic joists installing baffles. The baffles are needed to keep the blow-in insulation from falling out of the attic area and into the soffits. The roof over the garage has a shallower pitch towards the edges (if you visualize a pizza hut roof you’re not far off) which made it especially tricky to get access.
Once the baffles were up we picked up the blow-in insulation Sunday mid-day and had it all blown in in couple hours. The high pallet of insulation looked really odd on the trailer, but was secured well. Even compressed it’s not very dense, this was ~900lbs maybe ~1100lbs with the machine.
Lots of yard work lately, the tilling and composting last spring definitely seems to have paid off and grass is finally growing even in the shadiest areas. The bus was enlisted into the effort as plant transport, and we also picked up a big landscape boulder. A big spider joined in with guarding the garden hose, see brick for scale.
