The water heater installation is complete; here's the heater with all its plumbing. The sink and water inlet are offstage to the left. I zip-tied lengths of slit heater hose over the water hoses as a chafe guard.
Just forward of the heater the drain valve exits through the floor:
She'll be able to drain it using her air compressor; there's a air fitting on top of the tank, visible in the left foreground of the first picture. Close the faucet, open the drain valve, put air in through the air valve, and whoosh, the water is expelled. It's quite an exciting process.
Another thing Sis was complaining about was a "jiggly" ride; she was seeing things disarranged when she stopped for the night. Recently she just got new tires
, so that might be part of it; but I thought I'd take a look at her suspension to see if some old hot rod tricks could be applied.
I took apart the suspension and then dismantled the springs, only breaking one irreplaceable bolt as I did
. I bought a roll of polyethylene spring liner material, as used on street rods to reduce interleaf friction:
and reassembled the springs with the liner between the leaves:
I also rounded off the end of each leaf with my grinder, so it wouldn't dig into the leaf above it:
Hopefully, that'll give a bit smoother ride.
The eyes on the springs had plastic bushings inside, which were worn (imagine that!); I pounded them out and made new ones from Delrin rod. The Delrin is filled with Teflon, and is supposed to be low-friction and strong. In this picture, the old bushings are on the left ( dirty white), a piece of the Delrin rod is in the center, and two of the new bushings (brown) are on the right:
They pressed into the spring eyes with no trouble:
And then I took a look at the bolts which went through the springs and the spring shackles. The shackle bolts were very badly worn:
...so now I'm trying to get new bolts. Between the time that I bought bolts which seemed just right (but which I later determined to be too short) and today, two weeks later, when I went back, Lowes got rid of all their Grade 8 9/16-18 bolts. What the heck? I guess they were trying to defend their company motto "Never what you need".
Fortunately, we have a REAL hardware store in town, the superlative McLendon's, and I'll drop by there Monday after work.
