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?


I might try to get it closer but some times measurements can deceive or may
not be done accurately. Sawing technique can often render measurements
useless.

Use some scrap wood, make a frame and ask yourself, is that good enough?

Keep in mind that opposite parallel sides must be exactly the same length
also or even perfect 45's will not close properly. Use a stop to insure
same length "opposite" sides.
