The 5 cut method is very accurate but kind of a pita.. using a square and a dial indicator can get about the same results and is much easier IMHO.. Here is a example video showing the method:

I’m a fan of the dial indicator method as well. It’s worth a visit to Garageworks to see his other dial indicator set-up videos.

Hey thanks for the feedback guys. And I appreciate you all spreading the word.

I have a more recent video that compares the two methods:

I also use a dial indicator as shown by Garage Woodworks. Quick and simple.

There are many ways to “skin a cat”!
I prefer a laser interferometer with an accuracy 0.006 nanometers.

Nice to have different options that utilize the tools you have on hand.

I don’t have a caliper or a dial indicator, but I picked up this interferometer off CL for a song….

Thanks for sharing, I am thinking of replacing my sled and this gave me a few tips that I can use.

I watched the comparison video. Did it take any time to setup the dial indicator? That part wasn’t timed.

Charles, it takes about 5 minutes to build the “mount for the dial indicator approach and about 30 seconds to calibrate it. One of the Garageworks videos shows it being built. I use mine on my table saw for squaring the blade to the table, on my band saw for the same, and on my jointer for squaring the fence to the bed.

Another vote for the dial indicator method. Either works, bu the DI is quicker after some set up.

2 questions however….. because I don’t have a dial indicator, nor do I have a GOOD square….

Where would be a good place to go to get a decent dial indicator, and to get a square that is, square??

Thanks :o)
