I have been searching trying to find what equipment is required for vacuum infusion and I have been unable to locate specific information on the vacuum pumps and associated equipment to use. Most posts are from people who have already done it and seemingly managed to just find pieces in piles of equipment in their garage. For the less MacGyver-like among us, that was not enough information. Today, I stumbled across a site for vacuum bag veneering that has wonderful information, plans, kits and parts to build all sorts of different vacuum systems:

I am about to order the stuff to build an electric pump, which will automatically cycle on and off based on the vacuum pressure you set. I will post back once I have received and tried out the equipment, but I encourage the lurkers here to check out the site and free plans. I am just going to buy a kit, because I am more interested in building boats than building vacuum systems.

Anyway, I do still have a question for the group. How do I determine how big a vacuum pump I need. I have been under the impression that I don't need a big pump to infused flat panels, even large ones, but the site above seems to indicate that the size of the vacuum bag you use relates to the size of the pump. I would prefer to stay small for now, and intend to order a 3.15 Cu Ft/min pump . I am sure it will be ok for my test panels, but will I be able to infuse a 50' x 10' panel with a pump that size?

Thanks all!
