Subject : What Do You Veneer On (Table)?

Since I don't have room for a dedicated 4x8 table for vacuum veneering, last summer I made a portable 4x8 table surface using 1/4" plywood and 1" resin impregnated honeycomb. My hope was that the surface would be sufficiently stiff that I could set up a couple sawhorses about 5' apart, set the surface on the sawhorses, and have a reliably flat surface on which to lay the vacuum bag and 4x8 bottom caul. The surface turned out light enough to pick up and move easily, but has some flex and give, more than I had hoped. I'll have to check for flatness and twist each time I put it out. I'd like to hear what type of support surface others use when vacuum veneering larger surfaces.

My shop is in between tables right now.

Used to be a fold-down from the wall.

We're going to buy a frame press soon, so that will be stationary.

Presently, it's wherever we set down some plywood....not optimal yet.

Don,

What about putting 2 or 3 8ft long 2x4's under your table on the saw horses. I would think that would make things stiff enough. To make a rock solid honeycomb table that has no under support at that size I would make it with a double layer of 1" honeycomb.

One side thought. Its been my experience that a perfectly flat table is not that critical for pressing up veneers. I have found that veneer is not a thick enough material to create a laminating effect. What I mean by this is if you have a perfectly flat table and press some veneer onto a substrate that is warped, when you take it out of the press it will jump back to being warped. If you have a warped table and press a perfectly flat veneered panel on top of that warped table the panel will likewise jump back to being flat once it comes out of the press. Now if you lay up three 1/4" sheet on a warped table thats a much different story, it will come out warped. Veneer is just not thick enough to have that effect.

Sincerely
Darryl Keil
