I gathered some junk lawnmower parts to build a go-kart for my kids. The engine needed new rings, but was the cylinder worn in an egg-shaped pattern, or did it simply need slightly over-sized rings? I did not have a micrometer for measuring inside the cylinder walls. I improvised.
(I do not have an engine to show in this Instructable, and have decided to use a holesaw to represent an engine cylinder. The bottom of the holesaw represents the top of the piston.)
Step 1Measure the cyclinder's diameter

My substitute micrometer uses a wood block 3/4 x 3/4 inch cut in length to the diameter of the cylinder.
. I don't think using the hole saw is a problem. If one has need of your gadget, one should be able to get the idea with ease.
BTW, I've been meaning to let you know how awesome I think your submissions are. I may not have a use for many of them, or I might have done things differently, but I learn something from every one of them.
Exactly! I could go on but you summed it up perfectly.
Thank you.

lol... good answer ! This site isn't about..." i needed to measure cylinder wear so I ran to (store of choice) and bought a tool" I mean come on.. there are "ibles" about "how to walk up stairs" and "chopping an onion"(mine) to how to build a computer submerged in oil and building your own led taillights to a computer mouse that runs away when you reach for it.
This "ible" filled a need of the poster and may come in handy for another shade tree mechanic with out access to a toolbox/shop full of machinest tools and while it may not be up to the tolerances needed for a racing engine its more than adequate for the application it was desined for
Almost all yours works are very interesting, Phil.
