Unless you buy a fancy miter gauge with detents, setting the miter angle to anything other than 45˚ and square can be tricky. With the MiterSet you can quickly and accurately set angles from 5˚ to 50˚ in 5˚ increments. If you use their special detent bar you can set any angle in that range to within 0.5˚, albeit with a little math.
The MiterSet looks to be a piece of laminated plywood with two arched hole patterns and a slot for a miter gauge. Each hole is 5˚ apart and has the corresponding angle engraved next to it. To use it you simply place a peg in one of the zero holes and the other peg in the hole marked with the desired angle. You slide the miter gauge into the slot and when the fence touches both pins the miter gauge is set to that angle.
With their MiterSet for segments, instead of setting the angle you set the pin in the hole corresponding to the number of segments. In other words, if you’re making a hexagonal frame, instead of calculating the correct angle to cut all the segments, you simply stick a pin in the hole marked 6. The jig can be used for making frames with four to twenty sides.
Both the standard MiterSet and the MiterSet for segments come in two different versions: one for tables with 3/4″ x 3/8″ slots, and another for ShopSmith Mark V’s or tables with 18.5mm x 8mm slots.
If you live in the USA, you can get any of the four MiterSet models for $30 plus $5 shipping. If you live elsewhere you’ll have to contact them directly.
