Yes you can. If you use a fine tooth blade and go slow. It don't cut as fast as simular sized wood.
After cutting, be sure and clean the tires on your wheels as the small metal bits tend to imbed themselves. :wink:
I don't know if you have a scrollsaw, but they're ideal for cutting brass and aluminium. You can get blades specially designed for cutting metal and there's no risk of swarf getting embedded in the works.
If you're thinking of cutting thin or small pieces of metal, it might also be worth using a metal cutting blade in a hand-held fretsaw instead of going to the trouble of setting up your bandsaw.
I realise this info isn't directly pertinent to the question you asked, but I thought it might be useful nevertheless.
The avatar pic is of some fond memories of a vacation in Yellowstone Park. I wouldn't mind living there in the summer time, but I am afraid the winter might be a bit on the chilly side. :wink:
