What’s it gonna set me back? And what do I need? I’m using an airtech airvac 22
If you are already wet bagging you should already have most of the supplies you will need; sealant tape, vacuum bag, peel ply, tubing. You will also need spiral wrap, a resin catch pot ($100), and possibly flow media.
I would upgrade to a real vacuum pump which will run you $500-1000 for a decent pump.
I don’t have tubing or the spiral wrap. What’s wrong with a Venturi vacuum? Thanks
Too low a vacuum. You would like a very high vacuum, once to degas your resin, otherwise to create a void-free laminate.
You also want some means to regulate the vacuum. This can either be a regulator of some sort (preferably loss-less) or MTIhose.
A catchpot on the cheap can be a vegetable jar, or a beer bottle.
