Hey Grumpy Old Man (and other upholstery gurus)
Back when I had my 70 buckets restored the shop threw away all of the internals, like the listing wires, the springs that pull the center seat section down, all of it.
Just because it's still called Jimmy's doesn't mean Jimmy is alive. Jimmy was a great upholsterer. Guy that has Jimmy's business name now, not so much. Anyway, I "recreated" what I could with coat hangers, binder wire, and zip ties, and it functions pretty well. My problem is that with the side bolster wires pulled down the middle bulges up, and I'm tall, and now I've got "too much seat". I sit too high. I was thinking I could blow it all apart again and trim some of the center foam off, but that would mean undoing all of my work, redoing it, and hoping for the best. I had done an original pass with zip ties that was at least adjustable (one way only, you could tighten the ties) but the wire approach I used last is stronger but sort of permanent. I thought maybe a bag of cement on a towel would crush it, but that could take another 40 years of waiting... Thoughts? I just want to sink lower into the seat, more or less. This picture is before - very flat. The after (truck not here) has the bolster wires pulled down, making the bolsters and the center seat more prominent. By bolster I mean the raised side parts of the seat bottom that stop you from sliding out in corners (in theory), similar to the side bolsters on the seat back, but it might not be the right name.

Re: Hey Grumpy Old Man (and other upholstery gurus)
There's no easy out .Remove cover and slice foam horizontally from the center section only using a carving knife (yes a regular old $9.99 electric turkey carving knife ) works great for a cheap easy way to shape foam .A Bosch foam saw costs close to $500.00 and works the same way .
Starting from the front seam edge of the center foam gradually remove the foam from a 1/4" in the front to 1" in the back this not only will lower your butt section but will still provide leg support and as an added bonus sit you further back into the seat and you won't be constantly readjusting from sliding forward while driving . You can also use this process on the seat back section (center) only1/4"down starting from the top down to 1/2" just above your lumbar section then leave approx 4" and then trim some more below that 4" section to give the seat a hidden lumbar roll which will also sit you further back into the seat and gives you more of a custom designed seat feel rather than the straight back foam . This is why I always recommend to have new seat covers installed by your local upholstery shop and let them repair your old foam instead of buying expensive replacement foam ,They can custom fit your seat foam to your body ,For some reason ALL the replacement foam I've ever had to install over many years really wasn't worth the cost of the box it was shipped in. Don't use zip ties they will break use hog rings and hog ring pliers ment for the job http://qualitynylonrope.com/hog-ring...FdEYHwodvrME5g Last edited by Grumpy old man; 12-15-2015 at 04:54 PM. |

Re: Hey Grumpy Old Man (and other upholstery gurus)
How can you restore old foam? I thought it disintegrates after 45 years?

Some days I wish I could pay people to do this - at least when it's the 3rd or 4th time I've had something apart. I mean I could pay someone, I just won't.

Re: Hey Grumpy Old Man (and other upholstery gurus)
Is it possible to shave the foam from the bottom of the seat foam instead of shaving and shaping from the top?? Food for thought.

Re: Hey Grumpy Old Man (and other upholstery gurus)
Sometimes .. many seats have reinforcing material bonded to the seat cushion bottom to keep the seat springs from cutting thru the foam in the 70's most seats went to full foam construction with listing wires imbedded in the foam to attach the covers .In the mid 90's GM tried to use seats where the material was actually bonded to the foam making repairs very difficult with foam injected arm rests and head rests But most shops overcame the difficulties , The rumor was they wanted owners to come to Chevy dealers to buy replacement covers and not the local upholstery shops .

Re: Hey Grumpy Old Man (and other upholstery gurus)
Well that's cutting new foam, it was said to repair foam in your reply.
So that makes more sense you are replacing it. |

Re: Hey Grumpy Old Man (and other upholstery gurus)
You can repair the section that is bad and save whatever is still good Like just replacing the driver worn out section and saving the center and passenger foam .
