re: Rules aren't made to be broken- they're made to measure stuff.

All true and good info Stumpy. I rarely use a measuring tape in my shop. I just don’t trust them. I mainly use my steel rules. I actually do all the things you suggest, but I had to first take a masters degree in measuring mistakes. That education took me a lot longer than 4 years, and I still get it wrong more often than want to say! Now about that jig saw/saber saw controversy…………………..
