I really need help for vacuum bagging.

Hi all,

I have a lot of very small projects with kevlar and carbon fiber, but have never had a vacuum bagging system before.

Also I don’t have the space or the budget for the full scale setup for making things like race car parts.

I need a very small scale vacuum bagging system (for projects with dimensions on the order of 6 inches), and with a budget capped at about $200. (Just to clarify, I all ready have the epoxy, kevlar and CF)

Your advice is appreciated, thanks in advance!! :smiley:

There are a few rc modelers who use food savers for vacuum bagging.Try ebay for cheap used one.

An old refrigerator compressor work great. You can often get them for free. I ran an old used onw in continuous run system for 5 years.

For vacuum bagging is an refrigiator compressor good enough. Also for small parts you can use food vacuum bags, they are tight and strong and you can get them cheap.
A Vacuum food saver works, but you don’t have any time to place the bag.
But why don’t change to infusion instead of bagging? You need at least the same things, you can use a cheap vacuum pump for air conditions (about 69$) and a bit of spiral wrap or MTI hose.

Thanks for the idea. I thought about it previously, but didn’t realize the foodsavers pulled enough of a vacuum for the job.

Thanks for the responses guys. I didn’t realize there was a difference between infusion and vacuum bagging–need to do some research on the foodsavers as well.

Agator007-ACP Composites sells a really good vacuum bagging system for 120.00 dollars with the starting bagging materials. http://www.acpsales.com/Vacuum-Bagging-Systems.html
They also have great technical support to help with advising on the best systems/materials for vacuum bagging projects.

The $120 system from ACP doesn’t pull very much vacuum. I don’t remember right off hand, but I think it’s less than 10" Hg.
