TOPIC: Pumping and PMMA

If I recall correctly there is a user called Sizemik on this site who does this. Or did it only before PMMA, I am not sure.

Try sending him a PM

I think to remember that I read about Wayne or Dr C telling that pumping post PMMA is no problem but one should wait a long time ( several months )

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\".
