Should I Try For Better?

Today, for an up coming shop project, I tuned up my Dubby cross cut sled. After using "Three cut method" to square up fence, I got it within 0.001 over a 12" cut. Measurements were taken using a 12" dial caliper. FYI, the "three cut method " is actually two cuts. For more info on three cut method, watch Epic Woodworking's video. So much simpler than the five cut method, and a lot less math. You do have to be able to divide by two, though. That's where my error came into play, as original cuts were off by 0.0025. Using feeler gauges, I had to choose between using either 0.0012, or 0.0013

If you can't see it, it's not there.

Within the wobble of a blade, so I would say you nailed it. Trying to do better you might screw up.

Just amazed at how simple it was using three cut method to get it right on first try

What? Do you really think you can get away with that kind of tolerance?

I agree the two cut method is easier and less confusing. Here is that video of the method I use. It is for a sliding table saw but the method would apply to other setups.

Here is link to the three cut method that Bruce (@junquecol) mentioned from Epic Woodworking (Tom McLaughlin) in his post:

He is maiking a crosscut sled, but if you just want to see the "square-up" forward to 1:14:30
