Tool I.D. Please

[TIKI II]

My Great Uncle gave me these many years ago. He was a heavy equipment mechanic and I am guessing they are from the 30’s to the 50’s I’m sure at the time he told me what they were and what they were used for but I don’t remember. The pin in the holder is actually a drill bit that measures .0155 in diameter. Any ideas ? Thanks

Pretty sure it is a diesel measuring tool to measure the cylinder bore stroke/wrist pin wear. Could be wrong though. They would go in through the glow plug or injector holes. I would allow you to tell if there is excessive play in the crank bearings or wrist pins.

Like I said though I could be wrong.

The thing with the drill bit in it is a pin vise. It doesn't belong to the rest of the set as far as I can tell. Does the dial indicator attach to anything?

Possibly a depth gauge set.

Looks like an inside dial indicator set.

I was thinking inside mic as well. Can't see how this would work as a dial bore gauge though.

Wow thanks for the link, any ideas on the on the blue thing? The top and bottom edges are ground I was thinking some type of a scraper?

Once again like I said I believe he used it for checking cylinder stroke. That plate would be used to create a surface over a large hole so it gets supported on two sides aka bridging the gap/hole and you put the dial arm through the hole so you can actually measure depth. The thickness is on the plate so you can remove it from the overall length and give you an accurate depth measurement.

It appears to be similar to the starrett bore gage linked, which measures distance between two points within a range of measurement. The rods are extensions that allow measurement of larger sizes. So it could be used to measure cylinder bore, bearing bores etc in an engine.

The plate and pin vise do not belong. Used with the gage, perhaps but that is anyone's guess.
