Troubles taking a 360 .060?

Go to eBay and buy your own Sonic tester for a hundred or $125. They're going to charge us 60 to 80 bucks at least to do it at a shop. Use your own tester then you can do all the blocks you want to.

Well that's a pretty good thought. I have not done one since college. I think I recall a minimum spec being .200" Does that sound accurate to you?
