What tool is this?
Hi Guys,
I bought a set of bike tools, and this is the one tool that I don't know the usage of.
It is a cylinder, about 2 inches long, one side has a diameter about 3/4 inches, and the other side is about 3/8", It has internal threads on both ends, all right hand threads though.
What is this and what can I use if for?
Thanks!

Can't tell for sure, but it sounds like it might be a part from a dropout alignment tool. There are various versions of this from Park, Unior, Stein, Var, Campagnolo, maybe more. What you describe isn't from the common Park tool or, as far as I can tell, Unior or Stein. But, look at this photo of a VAR, might be what you describe. I can't tell if the small end is a stud or threaded.
Thanks!
I have posted 3 pictures.

You show NOTHING to give a sense of scale.
A coin or ruler would do much.
What are the thread sizes?

Regarding the thread size, the smaller one is M8 I think, I can screw a square taper crank bolt into it. For the bigger size, I think it is 15mm.
Thanks,

I guess Canadians can tell how big-
8x1.0mm seems pretty crank specific. 8mmx1.25mm is the "more generic" version of 8mm.

Do you have a caliper that you can measure the outside diameter at each of the step points?
I'm wondering if it would be designed to set, or remove races or bearings.

That's my most recent guess. Also, some reamers, HT and BB, have similarly shaped parts to hold cutters on shafts but I can't find one that matches and all I do see seem to have some sort of wrench flats to tighten (I assume) the cutter into place. Campagnolo headset reamers and presses had a similar, but not identical, part though I can't find an exploded view which would show the threading. Would be nice to have some diameter estimates to see if anything leaps out.
