This is great .. i worked in the TPi lab for 4 yrs after a 30 yr career as a composite boat builder .. i. Can also recommend debri netting as a flow media but not for tiny carbon parts .. its to ruff and actually bends the fibers .. I’ve seen it under the micro scope .. it’s the stuff used in the factories producing wind turbines .. we always infuse at full vac then turn down to half when full ..also wrapping the vac tube with 1708 fiberglass and having the peel ply go to that with th 1” set back on the flow media .. also trim the peel ply tight .. good stuff
Why do you leave the pump on once its infused? I turn mine off right after I clamp the in and out lines otherwise the pump will overheat. Its not pulling any extra air out so just wondering why?
Excellent question. I could have turned it off. I did not have any overheating issues. I left it on just because it is impossible to have a perfectly airtight bag and tubes. But if leaks are small enough the motor can be turned off.
I like the new setup! I tend to get some pits near the vacuum line as well. Those wont ruin your day or part. Nice work.

Lets not waste time and get the next test up and going
I'll be starting the next test tomorrow!
