Is it ok to glue up different thickness baltic birch veneer to make a thicker substrate?

For example, I have some 1/2" and some 3/4" baltic birch. Can I glue one of each to get to 5/4" ? Lately I have been using aliphatic wood glue for laminations of this sort, and reserve the Unibond for the face veneering.

TIA, Carl

Carl,

I tried it once on a conference table with disasterous results, so I would not recommend it. I always do same thickness cores or at least the same from the center point out. You could have a 1/4" in the center with 1/2" on either side or two 1/2" sheets with a 1/8" on either side. Any combination as long as its balanced.

Sincerely
Darryl Keil

Out of curiousity, what happened? Did it warp a lot? Would you not recommend it even for smaller pieces?

Ploh,

Yes, it did warp a lot, but was a rather large table, 5'x 12'.

On small panels it may warp so little that it wouldnt matter much. That's an individual judgement call.

Why not a honeycomb product?

It would be much lighter.

I have never worked with honeycomb. Partly because I can not buy it locally.

This is for a top to a tv stand. So it is going to have a lot of weight on it. 100lbs continuously. Does that sound like an acceptable application for honeycomb?

Carl,

My experience has been different from Darryl's.

I have laminated small pieces of 1/4" and 3/4" BB without a problem. I have seen other different pieces(2)(of different thickness)laminated together that seemed to be flat. What I was told was to be sure that the two outside veneers are parallel.
