Jeff and Kiefer, both excellent advice. I especially like the idea of aligning to the kerf.

Now I need a new combination square. I found out yesterday that the mitre side of body is not machined flat. When I laid it on the saw table without the rule, it wobbled! The square side seemed to be very flat. I’ve compared the squareness to other squares and it seems fine but I never scrutinized the mitre accuracy of it before yesterday. Are there any options between the $10 empire and the $110 starett?
