I know there are a thousand plans for box joint jigs but most call for the use of screwing a base to your miter gauge. Unfortunately, both of current miter gauges don't have the holes to do that with. Additionally, I'd like to make it adjustable and was thinking that could be done by making the key very narrow and simply butting the already cut joints against the edge of the narrow pin as opposed to a full size one to fit them over. Size could be adjusted by moving the pin closer or away from the blade. If someone has done anything similar, I'd like to have some input. Have a project coming up and would like to start using box joints again.
