Hi: The 45 degree lock-miter bit is a little difficult to set up, because each side of the joint is presented to the bit in opposite ways. One has to be flat on the table, and the other must be flat against the fence. Therefore the hieght is critical. The first time you set the bit up run alot of samples till it's perfect. Then save the last sample that you made that was perfect, to set it up for the next time you use the bit on the same thickness of material. Hope this helps..Woodnut65
