Subject: Pietenpol-List: Burl veneer problem solvedVacuum bagging (while an attractive option) looks like the best way to go, but for such a small project I'm not in a position to invest in more hardware.I ordered the appropriate glue and will build my own press. The panel is only 24 wide and 10 inches at the max height and I think a press will do OK. If not, I'll have a large, odd-shapped wooden frisbee for my German Shepherds.Thanks to all who replied off list for the tips.Sterling Brooks5TA6________________________________________________________________________________

I would have thought that you could laminate it like a kitchen counter, contactcement on bothsurfaces and then go over it with a roller. Does it have to be more complicatedthan that?-Mike McCarty ----- Original Message -----

Subject: Re: Pietenpol-List: Burl veneer problem solvedMike:That was my assumption too. But the burl arrived with a "tip-sheet." Of the recommendations they suggested are to very much avoid using contact cement. They suggest that the contact cement seeps through the burl. So I purchased a two-part adhesive as recommended by Constantine's.According to the tip-sheet, the burl is first dampened with a mixture of water, alcohol and glycerin ... then placed between Kraft paper. They then adviseplacing the burl under a flat wood panel with a minimum amount of weight. 24 hours later, the burl is examined to determine if it is still wavy. If it is, the above procedure is repeated until the burl is flat.... Then, for the next 5days, they suggest placing the burl between fresh (dry) Kraft paper to dry the wood out, replacing with new Kraft paper each day.The veneer is then kept under a weighted panel at all times until the bond is made.Lot's of work, but I saw a homebuilt at Oshcash last year having a burl panel and it was the nicest looking panel I've seen. It really made that wooden airplane look sharp.A fellow TACO has been nice enough to offer his vacuum bagging skills and I hope to do this process in a few weeks in the Dallas area. Maybe I'll post a couple of pictures on Mykitplanes in a month or so if anyone is interested.

Subject: Re: Pietenpol-List: Burl veneer problem solvedYou can lay down your press like this Bottom board - wax paper - plywood backing - glue (not contact, t-88 ok - veneer - wax paper - 1inch foam rubber- top board / clamp this together sqeezing the foam. The foam will insure contact over all of the veneer. C clamps and 3/4 top and bottom boards will work fine. Howdy________________________________________________________________________________
