I use a masonry blade in a hacksaw frame. put in a jig , then in a vice. Hols ot really good without mashing the shaft. Cut it as deep as you want, finish it with sand paper. Pretty quick & makes a good nock.
The holes are 5/16 11/32 & 23/64ths. Draw a center line on the 1x2, mark & drill each hole. Cut the board down the center & put a small nut & bolt thru one end. Works great for holding your arrow while wrapping the nock too.
