Greetings all...

I have been constructing a new crosscut sled, and the thought came to me,
how close does this need to be to make nice joints...

Instead of using a square I cut the sides off an 8" square of birch
plywood, I then ripped a strip off the first side and measured the
difference with a dial caliper, and over 8" there is less than 1/128
difference, but that would be compounded over 4 cuts right?

So would you guys try to get it closer of just leave it as is?
