To fine-tune my tablesaw blade as well as the rip fence so they will be parallel to the miter slots, here is a simple jig that I made and meant to be used in conjunction with a digital caliper.
I milled a 6’’ long hardwood runner to fit in width and height the miter slots of my tablesaw. At the center of the runner, I drilled a 1/4’’ hole for a 2’’ flat head bolt, and 1/8’’ hole 1’’ away from both ends to prevent splitting. Then I cut slots between the holes with a scrollaw (could be a coping saw). Finally, I countersunk the 1/4’’ center hole to conceal the head of the bolt.
The next step was to make a support for the digital caliper. Using a 3/4’’ thick piece of wood, 1-1/2’’ wide and 4-1/2’’ long, I cut a 1/8’’ groove with a standard 1/8’’ thick saw blade as deep as the width of the digital caliper. The lenght of the support may differ according to tablesaws. From 3/4’’ from one end, I drilled a 1/4’’ hole for the bolt.
To help tighten the digital caliper to the support with a fender washer and a wing-nut, I made a relief cut at the bottom of the groove up to the 1/4’’ hole again with my scrollsaw (could be a coping saw or even a hacksaw).
I hope you like it, make one and share it.
