that was the sign up on Crazy horse for years. my drop shop site in closed for repairs so I can't get in we are up to figuring out what is wrong with the seat I had redone 5 years ago. think we have a good handle on it now. they use 8 coil packs of stair stepping coils nailed to the plywood bottom. they were tied together in a simple pattern to make sure that all shared some of the load. so when things shifted under my rear this is what happen. the man had retied the coils on the drivers side in a spider web. the web shifted and the coils separated. and down things went. i discovered when I exposed this that most of the nailed were loose and the straps the coils were on were bent. they added a layer of foam to compensate for loses of padding. so it was tighten things up swap a row of bad bent coils to the center and screw it down tight then restring the damaged to the original pattern. put the first layer of burlap were it was when they built the seat and go up from there. as long as I was doing that I welded the nuts for the adjusted on to the frame work. so we didn't have to fight them putting the material back on. we are entering the final assembly part tomorrow. be glad to get this done I want my garage back. here are a few pictures
