Delta Bandsaw Zero Clearance Throat Insert
This is a drop in replacement for the circular throat disk that sits in the bandsaw table.
Since this is zero clearance, you will need to turn on the bandsaw and cut a slot in the throat disk. Use the slotline on the top of the disk as a guide. The disk should drop in to the bandsaw table snugly. If your printer is generating out-of-round circles, then this won't fit. Tighten your belts and try again.
