need advices !
going soon to vacuum my first board and, talked to a guy that is selling vacuum cleaners for a living, he told me, continus run for a shop vac is risky cause it might just burn out or better ( for the machine, not for me ) might turn out for overheat protection. IF it happens my board is garbage and i would loose the core, the few glass carbon epoxy hours of shaping......ect
so, mot so hot about using shop vac.
same thing about playing around with fridge compressor ( IF old fridge ( so not to expensive )) then it might just over heat or burn in the midle of vaccuming with half cured resin. ( and besides really dont want to spend hours bulding it ( not skiled machine wise ).
SO question is, IF you know something about vaccum pumps, are using, ect, what pump could you recommand me ( there are thousands out there ). anyone tried a venturi vacuum generator yet ? ( it uses pressured air suply from nail gun compressor for ex, witch i have !!!! )
thanks everyone
