RE: Vacuum or Press?
I have not gone back to a press type of system since going to the vacuum bag set I got from Aerospace Composites 10 plus years ago. I still need a flat surface and flat piece weighted just enough to keep the sandwich of shucks, skins and core from turning into a banana (the weight is external to the vacuum bag), but I know I use less glue and get good bonding at leading edges because of the over-all nature of the vacuum "pressure." The only consumables I have had to purchase with all these wings has been some of the nylon bagging material to make a "tube" large enough to handle the 18+" root chords of the 2 meter pattern planes. That fabricated tube gets used over and over... The nylon "tube" that came with the kit was sufficient for the .60 size wings but not for the later models. For storage everything goes back in the original box it was shipped in where it gathers dust until the next building season. Aerospace's little system works well for this application.
Enjoy!
