How much space should there be between a band saw blade and the upper guide blocks?

The guide blocks should have an air gap on both sides of the blade the thickness of a piece of paper. The upper guide assembly should be anywhere from 1/4″ to 1/2″ above the work piece being cut. If too much blade shows, it becomes dangerous.

Can I make new blade guide blocks for my UHMW saw?

The UHMW plastic guides are perfect for the 3/4″ blade that was on the saw, but would wear out very quickly with the 3/8″ blade. To solve this, I decided that I would make new blade guide blocks for the saw. The first thing that came to mind were sealed bearings, but I didn’t have enough of the size I would need to get it done.

What makes a bandsaw different from a saw?
