I have in mind to buy, possibly pre-owned to meet my budget, sheet metal shears that will cut 3mm aluminium. I'm after the type that you bolt on to a bench and it will have a fairly long handle.
I mean like:But, anyway, would metal shears/gullotine like the one I've indicated, enable me to cut 3mm aluminium without warping the aluminium? Could I get a straight line cut?
I'd be cutting out sheets around about 410mm x 300mm. I wonder what size of shears I'd need, I mean the length of cut.
