I'm curious as to what a good set of tools for checking clearances in a motor will cost me, as well as what brands are the best, what brands are good enough, and where to get them. Thanks.

 

More then what it would be worth to you most likely, some of the presision tools we have at work are a couple grand each.

 

Good measuring tools are expensive. My father-in-law is an electrical engineer and used to work at the Starrett Tool company as a machinist. He has a set of their precision measuring tools that he uses in his work. The tool box and contents are worth maybe $10,000.

Since I really like good tools, and I can get Starrett through him, I bought a basic set of Starrett measuring tools designed for automotive use. Sounds impressive, but what you get is: 2 - 6" Outside Micrometer with Interchangeable Anvils and Standards, 2 1/2 - 6" Cylinder Gage, Disc Brake Micrometer with a range of .300" - 1.300", 22 Leaf Thickness Gage. This retails for close to $700 . I also got their basic "Toolmaker's Set" that consists of a 1" Ouside Micrometer with carbide faces, 6"/150 mm Dial Caliper, Spring Tempered Precision Rule, Lastword Dial Test Indicator with Universal Shank and protective case. Also ~$700 retail. Between the two, you have the basic measuring tools needed for most mechanical work.

You do not need tools of this quality, but you did ask about the best! The Craftsman line at Sears is perfectly usable and less expensive. I looked on the Web and found a 4-pc set of Craftsman micrometers for $100, about the price of one of Starrett's.

I thought you guys got lost in his question at first. Craftsman will do just fine for the do-it-yourselfer. Micrometers, Calipers, and a dial indicator will get you pretty far. Anything needed beyond that I'd leave up to a machine shop.
