Thanks in advance!
I have a 5' x 12' vaccum table -- I place 12 fixtures along the X axis -- 12"W x 60" (Y) long.
We've been making these fixtures out of glue-ups (Alder, plywood, poplar, etc) They are 3" in height -- so you can imagine they are heavy.
We machine contours on the surface - vacuum area and a channel to run the vacuum gasket material in.
My Question: Is there a light weight (but durable) material you've come accross to build hold down fixtures?
Again, these fixtures are 12"x60"x3"
Thanks.
