Hi Martin,
I do have a vertical bandsaw,bought years ago for woodwork,and I have used it to cut sheet steel,from time to time. I just dont like the idea of getting metal chips embedded in the rubber tires of the wheels [very difficult to remove them ]
I was thinking more along the lines of a circular saw,as used for woodwork [not a chopsaw ],perhaps running at a lower speed. I have cut Ali sheet on my benchsaw,so that,s what set me thinking.I know that the speed of my saw is much too fast,so perhaps a slower running machine ? I have never seen any such machine so I suspect it,s a non-starter.
These are the kind of things which keep us busy !
