Large Vacuum Bags for Veneering Large Curved Panels
Question
Forum Responses
From the original questioner: Here's some additional info on the panels - 10'0 edge is straight, 6'0 edge is curved. Grain runs in 6'0 direction. Substrate is 2 layers of 1/4" plywood with seams overlapping. If we were to try laying over 1/8" substrate, what do we do at the substrate seams? Is 1/8" hardboard (masonite) acceptable? From contributor D: First of all, get substrate large enough so you don't have seams - or make it if you have to. Use a vacuum bag and start the bend as you make the substrate. Secondly, yacht hulls are vacuum bagged, so a larger bag for these panels is easy to make or buy. Use Unibond 800 or similar, and do a few tests first if you are unfamiliar. Good vacuum and form, single face substrate, and proper glue take out the guesswork. From contributor A: You can make any size vacuum bag using mastic tape. I helped bag a 42' sailboat hull. From contributor O: There is no size for vacuum bags. Look up Aero-tech.They have bags and something called Tacky Tape by Schnee Morehead. I have built bags 15' x 45' and 26 x 26 x 26 square envelope bags. They should have everything you need. Would you like to add information to this article?
