Have visited a few sign shops with stomp shears that they use to cut .040" and .063" sheet aluminum and 3MM ACM and they swear by them. I'd like to get one for my shop. I have called a number of OEMs or dealers for a 52" wide stomp shear that cuts 16 gauge mild steel asking if that machine will cut .063" aluminum or 3MM ACM and either they say no or they don't know. Does anyone out there have experience with stomp shears and if one that cuts 16 gauge mild steel will work for a sign shop?
