cutting question - oldskoolron - 10-04-2016 had this alloy outboard pod sitting around for few months so was thinking bout cutting it up and using the alloy for whatever jobs I want .I have a32amp plasma and have cut upto 3/8 thich steel .the pod is all 5/16 so I was thinking bout yseing the plasma is there anythink different I need to know from cutting steel cheers in advance RE: cutting question - Dr Stan - 10-05-2016 In general it takes higher amperage to cut aluminum than steel, probably due to the aluminum oxide on the surface.  32 amps to cut through 5/16 aluminum sounds on the light side. However I'd still give it a go even if it takes multiple passes.  I recommend using a wire wheel in an angle grinder to clean off the oxide where you plan to cut. An alternative method would be to use a reciprocating saw to cut up the unit, or an aluminum blade in a circular saw. RE: cutting question - f350ca - 10-05-2016 I'd give it a go. I don't cut a lot of aluminum, think the tables for the plasma table say slower feed rates than steel. The cut isn't as clean or smooth as steel but usable.
