Metal cutting band saw machines for cutting thin metal, ie under
1/10th in thick require a relatively slow speed for the saw, as they
usually have teeth from 16 thi to 32 tpi. so a wood cutting band saw
machine is usually too fast in speed of the blade.
Therefore you would need to change the drive system with different
size pulleys to get the right speed for the blade. Also you will need
the bands made up in the right blade material and correct size!! for
the machine you have in mind.
If you can get your wood band saw machine for relatively little
money, then its worth considering.
I use a a metal cutting band saw for the odd shape I dont want to
comission a blanking tool for. the blade is 24tpi by 20/1000th in
thick and 1/16th in deep.
will go around a 1/4in radius.
I buy it by the 100 ft in a roll. to join it I silver braze an
angled scarf joint some 1/8th in a jig, using a paillion between the
scarfs flux, heat then allow to cool.
Clean up with a file.
Hope this helps.
