Then there is everybody's standby -the band saw circle cutting jig.
Mine isn't greatly different than others, but adding more sliding table to the left of the blade, a stop [so the cut starts just in front of the blade] does make improvements.
Because you just push the wood into the blade until the jig stops, then start turning, you don't have to size the wood, prior to making a spin cut.
Having more table to the left of the blade both works as a counter balance and reduces the amount of saw dust thrown on the table, as opposed to being drawn down the throat plate.
The reason I have what you want is, I never lent it out before.
Scraps are a myth.
