Guide Block Circle Cutter
This jig attaches directly to your band saw's guide block assembly, unlike other circle-cutting jigs that clamp to the saw table. To install it, remove the guide block locking screws and replace them with 5/16" 18 tpi threaded rod (or bolts with the heads cut off). I slotted the ends, as shown, in order to leave these screws in the saw for adjusting the guide blocks with a screwdriver.
