It your band saw one of those freestanding units with vice-like clamp and an automatic shutoff switch. I have one of those HF band saws that can cut 4" square stock. They cut straight enough for a part that will be welded later. a 1/16th inch error is is OK. Those saws are great, mine will do 4" solid stock. It slices round stock well enough that they can be faced in a lathe without to much work. It's a great tool. I set up the cut, turn it on and come back later and it's done.
If it is a hand feed band saw with a flat table. Then make a jig to support the far end of the tube, cut it a little long then use an angle grinder to get right down to the scribbled line. Again, grinding to a scribed line by eyeball is good enough for parts that will be welded, The trick with a hand fed band saw is improvising a jib so the part only moves the way it should On Sun, Oct 16, 2016 at 11:46 AM, John Thornton <j...@gnipsel.com> wrote: > Actually after thinking about the problem and the tools available I > would cut a section out of the pipe above the base plate by scribing a > mark all the way around and only cutting one side at a time with the > band saw.
