Subject : backed veneers?
Posted : 2007-09-18 11:54 AM

I typically work with raw veneer, but I have a buddy who wants to do something a bit different, and I have a question or two. He has a piece of carpathian elm burl on a paper backing, and he wants me to press it to 3/4 plywood in building a 36 x 36 tabletop. The tabletop will be fully framed in solids. My questions are... will we need a backer veneer? If so, paper backed I guess. Would species/grain direction matter? Also, I always use Unibond for my raw veneers, but in this case, wouldn't aliphatic do the trick? Any advice would be helpful. Thank you!

I treat paperbacked the same as raw veneer. They can be nice because you really don't have to worry about bleed-through, except for seams.

You definitely want a backer veneer. I don't think that the backer absolutely has to be paperbacked, but if you want to be safe, go ahead. Just make sure that whatever you use, that it's the same thickness. That's what is really critical.

Grain and species won't matter. Your elm is burled, right? There's really no specific grain direction to a burl, anyway.

My preference is always Unibond, with the very rare use of West System epoxy.

Aliphatic glue is another word for PVA's right?

I'm not at all a fan of PVA's for veneering. Some guys here use PVA's all the time, but my 2 cents is thumbs down.
