Notes to myself on this test pull
- Could not achieve a vacuum with the plastic tacked to the table. This could be because I have joined two pieces of table top to achieve the length required.
- Putting the mold in a bag works much better. It is easier to arrange the plastic as it is pumping down, so that there is no bridging, i.e. less pleats. I used an extra piece of plastic underneath the mold for protection around sharp corners etc.
- The vacuum pump works much harder with this mold; possibly the wood in the mold is degassing.
- I've been getting away with the Home Depot plastic sheet, I don't see the need for buying more expensive bagging materials.
- Hats off to the guys doing resin infusion, achieving a vacuum is tough enough for me, thinking about how the resin will flow... is too much for me. I just want this one part done and move on.
