I have a 1939 IH 1/2 ton pickup that I'm restoring and have a question on finishing the interior. This falls into the area of restoration, though not related to metal. Do any of you know how they formed the pressed cardboard that was used for the interior surfaces, There are several complex curves that need to be made and then kept that way. I've searched the web but haven't as yet found anything.
Thanks, Jim

Jim,
is that the headliner your talking about?
LeBarron -Bonney should have the cardboard type material.
Boy i know way back when?? in a Skinned Knuckles magazine
i think they showed how to fabricate one. A form was made
and they steamed??? the cardboard material and clamped it
into place on the buck. let dry/cool and trimmed.
The cardboard type material is waterproof. Hope this helps!

Jim,

The cardboard stuff has a few names one of which is " waterproof panelboard"

Here is some info by a trimmer who uses it.

I never knew it but they say "moldable plastic panelboard" can be shaped with heat.I may have to try some of that myself. Always something new coming out.

Thanks Ron and TT. The Hotrodders site was helpful, although it's not exactly what I think I'm looking for. Yes, TT, the headliner is part of what needs to be done. But Harvester also used it for covering the firewall over jute insulation and all around the cab as the finished interior. There appears to be some indention pressed into the board surface to make it look grainy, kinda like a basketball surface.The trucks I have, have some pieces of it left in places with the panel clips still in place. The IH cab has some pretty small radius curves (probably about 4-6 inches) and the radius's go in two different directions in the "corners". (Somewhat like a 90 degree segment cut out of a sphere, if you can picture that) and that's the part I'm concerned about being able to get the board to conform to and have it hold it's shape. Guesss I have a reason to pull out the "Skinned Knuckles" pile to go through...again.
Thanks again, Jim
