TOPIC: Pumping and PMMA

So you can pump after PMMA?

Absolutely! I hang for 10 - 15 minutes and follow with a 5 minute pump session. The amount of vacuum pressure and the time spent in the pump must be carefully monitored to prevent damage and ensure success. I\'ve gained another .25\" in EL using this technique. Now a solid 8.25\" NBPEL x 7.5\" EG. BPEL is 8.5\".
