I have been meaning to make one of these for a long time. In my current project I have need for quite precise height settings on my table saw blade and therefore I decided to make it at long last instead of fiddling with just the vernier alone as I have done in the past.

It was a quick job and therefore is stronger on functionality than on looks.

My vernier’s bottom jaw seems to be big enough and therefore I did not make the foot as shown in the plan. If I see that it would be better it will be quick to add one.

For those interested my SketchUp plan is available here

Ok, I’ll ask the stupid question….it won’t work right…its upside down? Ie. it won’t read correctly…you’ll have to do a calculation after every adjustment to blade height?

BTW, I’m sure I’ve got it wrong somehow. And outside of getting the height read, it looks good to me …simple is almost always better.

Thanks!

The digital vernier has a zero function. I take the vernier jaw down to the table saw top or router table top and then zero it. When you raise the blade it gives a negative reading but that is about al you have to do is ignore the negative sign. Otherwise the reading is straight forward without calculations. With a normal non digital vernier you would have to do calculations though.

It works and gets the job done. How easily does it tip over?

The feet are 20mm x 20 mm (3/4 inch). It stands on it’s own. I think it will be steady enough, but time will tell. If need be, I will make the feet a bit larger, 1 inch (25 mm) sqr. by screwing a square to the bottom of the feet.
