Message: [QUOTE="WoodsRider, post: 348547, member: 16545"] Personally, for the piston, I would buy a micrometer. Calipers are not that accurate when it comes to measuring diameters with such a tight tolerance. For the cylinder, a bore gage is best, but many people do not know how to set-up a bore gage properly. Using a known standard (setting ring) is the most accurate method, but you can use a micrometer if you're careful. I've been involved with metrology, inspection, gage selection and gage r&r for a long time. I've seen good parts get scrapped and scrap parts get used due to inaccurate measurement techniques.
