Topic tags/keywords: router jig joining

Hello all,

I have an INCRA IBOX jig that I can’t seem to get the fingers to space equally across the board. I have leftover material after the final pass. I am looking for the equation you use to figure out the width of your boards to fit 11 – 3/8” kerfs? INCRA’s formula does not work. I am attempting to make a finger joint box. Measurements are 8×10x whatever width needed. Any assistance would be greatly appreciated.

Ever tried measuring the finished cut with a vernier caliper?

I agree with TheFridge. If you are off by only 0.001” per finger, that is 0.011” across the 11 fingers which is significant.

.005 can make the difference between a tight joint and a loose joint. Vernier or dial calipers are a must have bud.
