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.

Pretty cool. Glad you posted this because I’ve needed a more simple way to align my fence. Thanks.

Great job, Serge !

I simply ripped a tight-fitting piece of oak for my miter slot, and glued a piece of metal on it.

My dial indicator, with magnetic base, locks right on to it, and does the trick rather nicely.

Yours (of course) is far more elegant, though :-)

Another plug, though, for the MasterPlate—a NICE way to take ONE MORE variable out of the equation. Slips on the arbor, in the place OF the blade, and … is Dead Flat.

It won’t help a wobbly blade, but it WILL tell you if your arbor, fence, or miter slots are part of the problem, and—if your blade IS wobbly—what are you going to do, anyway ? ;-)

Having just tuned up my table saw this weekend, that really caught my eye. It would have been handy having that around. Great idea.

In a perfect world, each continent would make ONE, and it would be sent from LumberJock to LumberJock for, say, one week.

Get it.
Use it.
Mail it on to the next person.
The last Jock paid for YOUR postage, so you pay postage for the next Jock.
Nobody pays postage for overseas shipping, since there’s one on every needed continent.

Sorry. That nagging socialist itch just came out, again. Need coffee LOL !

That would work well with a dial indicator also.
Great idea.

Great idea, I have seen it also for the dial, but never like this.
