Bandsaw is driving me bonkers. If I set the hydraulics to crawl it eventually cuts, if I do anything else the blade comes off. I have adjusted until I am blue in the mouth. It has to go.

I want to cut up to 6" aluminium and steel bar and tube and cut it squarely, preferably with a blade that can't come off.

What do I search for? Very hard to find what you want if you don't know what it's called. Does it even exist?
