I'm switching from clamps and cauls to vacuum for veneering small panels, 4-7" wide x 11-15" long, doing them in batches of about 100. What's the best method, considering bag size, glue choice, how many to stack, how many bags to use, to cycle through about 100 of these in a day, with a helper available to speed things up.Have a 6 CFM venturi system.Veneers are not necessarily the flatest.Thanks!

Al, if it's possible I would do these in large sheets and cut them apart after gluing. Small panels do not receive as much overall pressure as a larger panel would.

veneers are special high value; can't do in big sheets. Also panels are solid wood banded before being veneered. Have to do in small panels.

Al,

Well, I was with Earl's idea, its the way I'd approach it. I understand this will not work in your situation.

The first thing I would suggest is a frame type vacuum table over a bag. With all your parts I dont see sliding them into a bag is going to work. With a table you can set the parts in place and then bring down the lid.

Here's how I would do it. Lay down an amount of parts that add up to a nice square or rectangle on the table surface, could be enough to fill up a 4x8 table. Keep all the parts close to each other, no more than 1/4" apart. Then lay a full 3/4" sheet over the whole group making sure this sheet does not overhang the parts around the edge by more than 1/4". You can then start another stack on top of this one and keep on going with more stacks. You will definitely need to use a slow setting glue like urea resin to do a bunch of parts at one time. A white or yellow glue is not going to work. It doesn't have enough open time.

These are my thoughts

Sincerely
Darryl Keil
