I got the brakes wired up. 14-2 Marine wire with heat-shrink adhesive crimp connectors. Sorry for the poor quality pictures.
Right side.
Left side (leads come from the front to here- that the wires coming up. Then from here to the right side.
And the axle.
There are loops welded to the axle and the left side frame channel to support the wires. The second wire is an 18-2 (way too heavy, but the smallest gauge marine wire I could buy locally) for the thermostat. The electrical attachment studs and nuts are brass, so I kept them but used locking compound. I’m a big fan of locking compound but it didn’t exist in 1950. The cable clamp studs and nuts are mild steel. I replaced the nuts with stainless, and again used locking compound.
There was a stud but no separate clamp for the wires from the left side brake to the front, so that’s currently not supported. Next time I go to the hardware store I’ll get the proper wire clamp.
Note that I hadn’t attached the wall to the new floor yet. There’s the 2×2 at the base of the wall, which sits on the floor, which sits on another 2×2. When all the floor is in place I’m going to adjust the height at four locations with a laser level. I’m afraid of building in stresses if I lock the floor to the wall when it’s not level. I was preparing to install the new floor section and realized that the lower part of the wall was spreading outward by about half an inch on each side. Not good. I decided to put in two screws for each floor section, just a couple inches apart. At the rear end of the first section, the rear end of the second section, and where the wheel cutout begins at the third section. That should allow enough flexibility when I do the final assembly. If necessary I can pull the existing screws and put new ones in a different location.
As I move down I am tying the floor sections together in the center, with a four inch wide section of plywood. Same stuff as the floor. I also have some 2×4’s on jacks so the floor is stable enough to walk (carefully) around inside.
I got a nine foot pipe clamp. Since I don’t have a helper to hold the far end, I had to get creative. A couple temporary deck screws and some string did the trick.
And it was easy to crank the near side flush.
And the new floor is now in, and the supports for that floor section is back in place.
I don’t normally leave pile of junk in the driveway. That’s the last floor section and some associated detritus. I’m taking two floor sections at a time to the local dump.
I have one more day of good weather tomorrow, and the plan is for the next support and floor section to come out.
