I could only find the micrometer set that goes up to 3" in the small brown toolbox, looking for something better than calipers to calibrate cylinder bore gauge to measure cylinder bore (which is nominally 89 mm / 3.50394 inches).
Nope, sorry. …
When do you want to use it? I can grab one from work for you to borrow to check.
Next Thursday 7:30 is when we will be working on engine next and removing crankshaft
I have a very unusual measuring tool that I’ll donate to the machine shop. It is a precision Periphery Tape Rule. Think of it as a flexible metal measuring rule that is made out of 1096 clock-spring steel. It is used for measuring diameters from 0.750 inches to 7.000 inches. You wrap the rule around the surface to me measured and read it just like the way you read a micrometer with an accuracy down to 1/1000 of an inch. You can use it to measure crankshaft journals or any cylindrical shape. Compare your results with a micrometer, if the two answers do not agree, then the surface is out of round. It folds up into a small round metal can that is similar in size of a can of shoe polish. Sorry, it won’t help you measure your cylinder bore, but it has many other uses around a machine or engine shop. I’ll be at the Makerspace on Saturday around 11 AM in the Science area for a meeting.

Thank you! I would suggest leaving in the 2nd drawer from yhe top of the Kennedy chest.
We always referred to these as “Pi Tapes” as they measure the circumference and read out the diameter.

I just put the new measuring tool in the Kennedy tool box this morning. The metal container is inside a small plastic bag with the instruction sheet. Enjoy using it.
