Thread: whats this?

Don't quote me, but it looks like the measurement indicators that are mounted on the feed axis of lathes/mills etc.
Apologies for the artwork quality

Screw jack?? For accurate height adjustment on machine tables.
Especially if there isn't a hole thru the core piece for screw.
just a thought off the cuff...!

its probably what it was advertised as?

lol he didn't know what it was either.
Like AndrewOC I thought it was some sort of screw jack, but it just spins, now change in height. The range on each dial is 3mm and .100". I should mention that the black part is mounted on a spring and has about 1mm of movement up and down.
Durdge39 They look just like the dials off a lathe but they are geared to each other. Although there is enough "slop" that they can be disengaged and turns independently.
It just occurred to me that I didn't give any scale
The Dia of the bottom piece is 52mm, the black piece 41mm, the total height 36mm.

and neither do I...and I guess niether do you...but what intrigues me most is!....
why did you buy it?


I have plenty of stuff around around here that I must be able to sell to you (stuff that that should have been taken to the dump long ago) .....I must photograph,stick it on ebay and await your bid...lol

Well I thought I knew what it was. I was wrong.
I'm starting to wonder if its a tech school project, but the level of finish is pretty high.

It looks like graduated wheels for a lathe or similar. The gears are for transposing, to indicate both metric and imperial. There are 2 scales, which would support this guess.
