Second Vacuum Pump and Bag

Searching Ebay for GAST or GSE vacuum pumps should find you one of these for under $150.

Refurbished GAST style diaphragm pump bought on ebay

This diaphragm style pump is great. No oil consumption. Far more quiet than the rotary vane style for HVAC work.

Checking pressure of vacuum bag test
New black butyl tacky tape also sealed the film perfectly. The new pump was able to pull and hold -80 kPa. That will provide about 10-12psi of vacuum to compact a layup. Simply a bagging test.
