Laminate/Veneer vacuum press?9/20
We are considering buying a vacuum bag press for the occasional need of laminating full 49X97 sheets of plastic laminate 3/4" material (particleboard core), and would probably also use it for wood veneer work, particularly on complex (arch-type) veneers.
Would need to be something I can reasonably store aside when not being used.
Looking for suggestions. I'm particularly concerned about the possibility of plastic laminate tearing the vacuum bag, so any advice there is particularly appreciated.
A urethane bag is more durable than a vinyl bag. Costs more, but tolerates sharp corners better. You can also pad the corners with taped padding or similar, if it does not disturb the rest of the panel.
We often use a full size caul on top of the veneers we are pressing. Waxed shower liner is the current favorite, but good melamine will also work. The corners of the caul can be sanded over to ease the points.
david, can you elaborate on "waxed shower liner" - that sounds interesting and i'm incredibly tired of waxing hardboard as cauls...
Waxed Shower Liner is painted hardboard that resists glues. Mostly.
