Door skin sheeting??


I did a quick search and came up with nothing. I swear I've heard of using door skins as sheeting for foam cores. Anyone know what I'm talking about? Better yet, where I can get some. This stuff from Aircraft Spruce and Supply is spendy as hell!!!

Thanks all, IRJ

the only door skins I have seen are about 1/8th inch thick and I used to be able to get them at Home Depot or Lowes but I dont know if they are still available.

Maybe there are thinner kinds out there.

your talking about Luan plywood right? Check at Home Depot or Lowes. A few years back I got some 1/8" three ply stuff from Home Depot.

I've seen it mentioned a few times, but this post is the only one I can remember that got specific:

I'm interested in this, too since I've got a wing to sheet and a tight budget.

Door skins sounds like it would have some potential.

I'll tell you what I've been working with. It's a very thin plastic...I call it paper-plastic. It was used in holding the System CDs that came with my MacBook Pro. It a super thin plastic that seems pliable enough to be used as a method for covering foam. I'm currently researching the material.

OK folk. Doorskins are generally 1/8 or 1/4 Luan, that (once was) a fast growing Phillipine Mahogany. That particular wood is now mostly gone, and Luan (check for actual spelling, it's rather strange) and Luan is a strange, similar wood out of china. Do some funky google searches, and you'll find it.

I can't imagine using it for wing skins in or on any planet, slope or not. I'ts cheap, splinters like mad when cut, and can be unstable. If you want a super durable, stable skin, try phenolic backed veneers. You can choose your wood for finish, and have the extra stability and strength of the phenolic backing.

Oh, Sorry. I see the original issue was price, right? I picked up a 4'x8' sheet of nice, -nice- honduran mahogany veneer with phenolic backing for around 60 bucks. How many wings can you do with that??

If you go with veneer, (could be interesting, haven't seen anyone else do it) try Alder or Birch. Fine, even grain, and easy to finish.

Rick James- So Cal? Where? Check Anderson Plywood Sales (LA) That's where I shop.

I've done a few wings with the phenolic back veneer, I got Cherry. It is tough as 1/64" ply and cheap in comparison, I think I paid around $50.00 for 1 2x8 roll from a woodworkers club here in CT. I'm just finishing some Jarteron wings skinned with it right now.

I can get 6 wings out of a 4x8 sheet. Our P-40B wings with 24" cores.

Sean the ply is one of the high dollar items. I have been checking on balsa packs at Michael's or Joann's, my wife gets 50% off coupons but the thinnest I've found is 3/32", I was hoping to find 1/16" but no luck so far.

Ganahl Lumber in O.C. would have door skins. I agree the backed hardwood veneers are a better choice. Austin hardwoods in Santa Ana has a nice assortment of veneers as well as glues and vac bags. Like a candy store for us finish carpenters.

I find that that single ply veneers tend to split along the grain.

I've discovered that ply is stronger.

You might try North American Plywood (located in CA). I buy all my 1/64, 1/32, and light ply by the pallet from them. They have got every kind of plywood under the sun.

That seem's kind of thick, but know this the ply's are not the same thickness. I've made a few sea kayak's out of the stuff, but you really have to seal them with epoxy for that kind of building. I've used the Luan for bulkheads and fuse side's to good effect, I haven't seen it in awhile though.
