Of the 36 years I've been working with metal, my main mode of cutting stock has been...the hack saw. I have 3 saws with different tooth spacing. I've cut 3/4" thick steel plate 8" depth, (of course flipping it to cut through); 4" diameter aluminum. I never enjoyed it but, a man's gotta do what man's gotta do. I have to make some soft jaws from aluminium. What I have is a block 3"x4" x 10". (I also have that follow rest that I'll be making out of 1" thick hot rolled.) I better get new hack saw blades.
