While watching them perform the test (With a contraption I am not familiar with), it became apparent to me that there were some suspect accuracy issues because of unsteady hands. I asked for another person to perform the test and WALLA! I was at 83MM? Or whatever was the exact spec. The previous readings taken when I was at the drivers meeting were 85 and 86 (With some decimals
Mike, Sean, Jim and others made reference to this or another sort of through the spark plug hole cylinder bore measuring tool.
Can we improve on a given tool or concept a better tool. First we need to ask ourselves, what are we going to do with the measurement taken with this tool? I would suspect, it's a red or green flag tool. Red flag, the head comes off, green flag your good to go.
Within this address https://www.hyperrac...?product=80-700 you'll find a through the spark plug hole cylinder bore measuring tool. This tool maximum capability is 70 mm or 2 3/4 inch diameter approx. We need a 3 1/4 inch diameter tool which may be out there that I haven't found. As you can see the tool has a cost. Also found a similar tool with longer stems, don't know the diameter capacity. This tool is $100.00 more than the first tool.
Mike Collins, you seem to have had experience using a similar tool. Care to elaborate, manufacture name, good, bad,???
Tool use?
Improvements?
