there are jigs for all sorts of percent's. a true 0% jig is a cnc machine, like the gg3. i have a cnc machine (not a gg3) and it's pretty wicked. cnc stuff is based as fuck > if there was a set of jigs to turn a block of aluminum into a lower with handtools that would be sick there are. iirc it's called a progressive jig set or something similar. i don't think there is a full set someone sells, you have to cobble together different jigs from different companies if memory serves me right, but yeah there are jigs to start from 0% to 20% and jigs that go from 20% to 80% and the 80% jigs
