Help with veneer going funky

Well I don’t have any help for you, I’ll suggest when the budget allows it, check out joewoodworker and build your own vacuum setup. I built the venturi setup for a few hundred dollars, and that includes making the vacuum bag.

okay, for the record, you cannot use heat to seat blister and bubbles on cold set glue.

joewoodworker does state in one of his FAQ’s that it is possible to use heat, however he also says you must do it QUICKLY…. apparently I wasn’t quick enough.

However, you can you heat to help release the glue while peeling off the bad veneer job!

Drop back and punt, have the first try stripped off, and I’m currently going waiting for the filler to dry, then reprep the top, and then go again w/ paperbacked veener.

Julian: Thanks for the tip. I was aware of the EVS plans that joe sells, and infact that is what I was going to get in January (actually I was going to build a vacuum table!)

250lbs of sand isn’t nearly enough pressure. Vacuum will give you 1000-1500lbs/sq ft. And even with vacuum, you need to be quick with Titebond Cold Press glue. The moisture will quickly swell the veneer, and it’ll bubble if you don’t get it in the press fast enough.

As for the bubbles, I’ve had a few bubbled panels come out of the press (due to user error), and have never had any luck getting rid if them.

I also built a Joe Woodworker press, and spent less than $150 several years ago.
