measuring tools
From previous work, my micrometers are not metric. What's the general consensus on measuring my 911 parts for re-build? Get metric micrometers, or deal with the conversions? Thank you! Jon

That's entirely up to you. The machine shop I use does the measurments in inches. Obviously it would be easier to buy metric tools but more expensive. Many of the books have the numbers in both systems anyway. For the measurements I do at home I find I only need feeler guages and calipers and have them in inches.

Hey, Thanks Andy! I'm not sure I want to go through all the conversions at home, and so far, all of my books have the info spec's in mm. Appreciate the reply. Aloha, Jon

I took Excell and made a spreadsheet with all the specs in it for my particular application. I then converted them all from mm to inches. It is so convienent to have them all in one place rather than flipping pages in a book or finding a particular spec sheet.
Now I can write down the measured spec next to the published spec and compare them at a later time. You can also add columns for multiple measurements. These would include before and after or triplicates for accuracy.

Depends on your reference for specs. My bentley manual has all the factory tolerances in both metric and standard.

Gentlemen,
Harbor Freight offers digital calipers that read in inches or mm. At the push of a selector button you can read either way. Perfect for conversions.
