Some time ago I bought a dial indicator and a magnetic tower to hold it. This was among other things for a major table saw tune up. Loved the dial indicator and hated the tower.

I made the jig below that fits in the miter slot, for adjusting the blade.

Then the tower broke and needing some very precise cuts, I wanted to use the indicator for getting the rips very accurate, I came up with this thingy.

Thanks for looking and having some fun.

That is awesome. I may completely steal that idea.

Nice save, I just hate to throw things away as bad as I hate to replace a tool that I know will break like the last one …

So it is used to measure the tolerances of LJ’s in a guessing game thread?? ;)

Madts, that first photo looks just like mine!

How does that new tool help setting up precise rips … I just can’t see it I guess!

oldnovice: Say you want to cut stock .75 in. Cut the stock a tad over size. Measure it say .79. Then put the dial indicator against the fence and then move the fence .04 in. Works like a charm. The on/off magnet holds everything in place.

OK, it was as obvious as could be!
I thought you used it to set up the very first cut and opposed to the final cut!

You can also set your fence against the blade, zero the DI, then move the fence; assuming your DI has enough travel for the cut. I rarely need to cut anything so accurately but it would be nice to have for those times.

Ok, the dimensions clearly weren’t a tell of any sort. The two radii cut at the base of the clamping arms for the indicator were there for the reason I suspected. Very cool, and no doubt much cheaper than anything from Starrett.
