re: Koa Kerfmaker

Thanks Eric and Dave.

Hi Dave, it is a gauge used to set the cut on the left side and the right side of a dado, using a table saw, to make the dado fit exactly over the  mating piece. You clamp the brass  jaw over the  saw blade to  take that into the calculation and then you clamp the wood jaw over the mating piece to use that dimension for setting the second cut for the width of the dado. The part is up against the kerfmaker which is against the stop for the first cut. Then flip the kerfmaker over to use the other side for the gage for the second cut. A video wood be better and Stumpy Nubs does a real good job with a little different in the blade measurement:   https://www.youtube.com/watch?v=0Iqi_bUGDek&t=12s
