Hi. Are there any tricks to adjusting a table saw so it is perfectly square? We have an overhead table saw (the blade is not in the table) that isn't quite square, and my father said years ago he even had someone out to try and make it cut true to 90 degrees, but it is still just a tiny bit off. The saw was bought in the 70's but is still in top shape. I think it is made by Rockwell.
Also I bought a cheapo mitre saw at Lowes (I think it is a Makita) with the laser sight. I have the same problem with it. I loosen the nuts on the fence and try to adjust it, but the fence just seems to keep sliding back to the same position, and I'm left with slightly crooked cuts. Funny enough, the problem is about the same on the table saw and the mitre saw.
Is there a "right" way to adjust these things so they are true, or is it more trial and error?
thanks, dwhite
