I need to bore some holes on a Bridgeport, 4.9152-4.9148 diameter. I have a Sunnen dial bore gauge, reads .0001 and the micrometer setting fixture so hitting the diameter should not be a big deal. The problem is I have to move the table to measure the diameter because of the length of the bore gauge. My DRO only reads .0005 so I worry about getting the table back in exactly the correct spot. I was thinking about making a good solid hard stop with a .0001 indicator on it. I'll leave Y locked and only move X. The next bit of fun is I need to flip the part and do the same diameter on the other side as well. Thinking about making a piece to bolt on the table, OD same as my bore diameter. Indicate it true to the spindle, set the part on it after boring the first side, it should be lined up with the spindle. Am I missing anything?
