Topic tags/keywords: question

Hello all, I am new to the site and have found some interesting topics on here that have helped me get started turning.

I am in search for a bottle stopper mandrel for my Central Machinery Lathe i purchased but didn’t come with a owners manual.

Attached is a picture of the spindle threads.

Is there any other information I can get you to help me I would.

Thanks for the help!

I am assuming the spindle does not have an MT.
That looks like a 3/4” to me. You will need to count the threads on the spindle. Although you are counting the valleys it is easier with my sight to line up the ruler at a peak and count to 1” then subtract one.
I think3/4 X 10 or 16 tip are fairly common.

Yes I believe it is a 3/4×10 tpi. Im trying to get to a 3/8×16 male and cant seem to find one. Does anyone know if this is available.
