Hi ya'll, long winded this AM. Energetic too. Just read 6 goggle pages and links for :
vacuum, press, veneer

Had a great two hours.:D :D

Thanks for info overload, I will repay the favor, but first:

Am lucky enough to have 5'x11' hinged frame vac setup at work. does anybody have any size vac frame setups? Problems with leaks at corners? Could be the guy who cut plastic, ya know. I am extreme with rounded platen corners and sheets quadruple folded over edges, it didn't happen cause of platen puncture.

Part two: Any experience with corrugated honeycombed impregnated with 'stiffening agent' ( i can't recall the additive), I used double sided skinned 1/2" panel mdf ( 4'x10' ) had 20-22 Hg in average. What are some of the Hg's you're getting??

I get a little burp along one seam, every sandwich ( for about 2-3", then back down) pressed between two 1/2" platens. Should platens be a bit thicker?? Burp is secure, panels dried in vertical rack designed for air flow, straightness ( and lumber storage ) for urea glue to flash off. Yes I had mdf framework, no crushed edges happened.

Part three: Hot temperatures in shop: keeping glue from flashing off for long double sided presses and mils laid down if anybody counts?? I use a powdered Urea glue and could add max allowable amount of H2O. Proper roller used, not sure on mils though??

Sorry mods if too long.
Thanks,
Aaron
