some people just need to move up to the 21st century instead of looking at 100 year old construction methods...

Seems like it comes in cycles - lighten up and every one get some fresh air. I like carbon Fiber, fibreglass, Glues, boats, resin, plywood and teardrops. Just cut out a 3/4 inch frame and skin it with whatever you want - doesn't matter what-'cause there is always someone who's gonna tell you it's wrong. you can still build an airplane like they did in the 40's and it WILL fly as designed, same with boats. Keep it simple and follow proven methods and you'll be fine. I've built four very solid campers and i don't have near the engineering expertise that some have. I have a master of theology degree - so I pray to God that it all holds together!

2 sheets of 1/8" door skin and a minimal frame make a door with a lot less stress on your budget that two 3/4" sheets of veneer-core and it more than adequate to have a little privacy in the bathroom...

I posted the chopper blade picture to show that they use the material where it's needed and the rest is just fluff. strength where it's needed and none where it's not.

in the old days they built a wing with the strength in the frame and covered it with cloth and flew at 150 mph. then the made wings with less strength in the frame and more strength in the skin and flew at 700 mph. now they make wings with all the strength in the skin and no frame and fly at 2000 mph.

anyway.... I'm skinning mine with two layers of 3/4" ply.. it's stronger!

You ever seen them move a house? there is a reason they go REALLY slow.
ever watch them move a mobile home at 55 mph on the highway?


The mobil home factory by where I grew up, (I don't remember the name, but its in Plainville KS) Glues the outer sheeting to the studs, and just puts enough screws in it to hold it while the glue dries.

Hey! you could use a layer of real tree fabric over the outside! or maybe some cloth printed with a carbon fiber pattern for a inexpensive carbon fiber look??? Wow, the ideas are endless.

Can you apply epoxy resin over ANY cloth? The goal being appearance and not necessarily structural rigidity.

Yes you can apply epoxy over any cloth that won't dissolve. In Navy, I was a Damage controlman. in caseof a water main break we had fibreglass repair kits. In training we used a dungaree shirt instead of glass cloth; it still held 150 psi
