Title: 5E3 cabinet
Post by: SacDave on April 15, 2015, 08:52:59 am
This is one of my custom built cabinets. They are made out off Cherrywood with Maple trim. The bent skin is about 3/16" thick. Each one takes about 30 hours to make.

Very cool!  :occasion14:


Are you using steam while bending the wood "skin"?  It's multiple layers bent then glued together, isn't it?


Cheers,

No don't use steam, I do use heat , heat gun also have a heated mold takes about 45min to bend each curve. The core is made of 7 layers of 1/8" bending plywood. I did just build a steam box to try some bends on 3/8" wood. Also I spent countless hours on the mold went from 36 C-clamps to 12 pieces of all-tread.

So you are saying you build up the sides with 7 layers of bending plywood? Are those individual layers bent around a form like the sides of a guitar? How do you glue them together without voids and warbles in the plys? Dozens and dozens of clamps?

The mold  has a 9.5" metal band (kind of like a strap) that pulls everything tight around the mold, there is also some other cross clamps .  The cherry wood skin I clamp it the same way after the shell is made. One thing for sure you have to work fast once you start glueing. I think the next one I might glue up 3 plys then after thats dry glue up the other 4. then the skin. I Don't know when I'm going to build another one  but I'll take a bunch of pics.  I want to try and steam bend the wood  but I don't think I can bend it faster than it will cool.  The plywood pieces bend no problem  you can bend them by hand . The Skin I pre-bend before I glue it on.
