Tore in this morning. Welded up the frame then started laying it out. I used a trick I learned from an upholstery guy we work with. It is also in Don Taylors automotive upholstery book. The coil springs at the sides tend to wear out so jam them full of foam to give them some more support.
Burlap installed with hog rings
Jute felt pad on top of the burlap.
The drivers ass groove was the only worn part of the foam so I only replaced a section of it.
I bought this pro foam cutter years ago and rarely get to use it so even though I could have done this with scissors I plugged it in anyway
Cotton batting on top of the foam
Those rods that poked through the side left these holes.
And here I got lazy. You know those iron on denim patches they sell everywhere? Yep. That is what I used
grassroots bitches
Stretched the old cover back on and hog ringed it in place
Looking clean under there!!
Since that went so well and only took an hour and a half I tore apart the back.
Oh yeah. There is the source of the bulging.... sigh...
And here is why. It is missing all the horizontal springs on the drivers side.
I racked my brain for a while trying to figure out something that wasn't jamming all that foam back in there. Upstairs in the garage I found an old chair and sacrificed it to the Falcon gods for its springs
These were cut down, bent to shape and put in place with more hog rings.
Fingers crossed.
I ended up replacing the foam on the left side. Again new burlap, batting and the old cover. I also replaced the sagging and broken cardboard panel ont he back with a piece cut out of 1/8" birch plywood.
All back together and in the car.
That was a lot of work actually. About 8 hours in total. The seat is comfy if a little firm but gone is that sliding towards the door feeling. Sadly the new girth has me sitting a bit too close to the wheel so I will need to mod the seat tracks to get me back another inch or so.
Total spent was $34 which isn't bad.
