I have one of the Harbor Freight 7 x 10 lathes.
I have a bicycle seat post that I want to reduce the diameter by 0.025".
The spindle head is to small to accept the post, the bed is to short

Any clever ideas how I could use this lathe to do the job. The post
is aluminum.
I took it to a machine shop, he laughed and said, "I've already spent
more time on this than the part is worth."

If you have a press available you could turn up some sizing dies and
push the seat post through those to reduce the diameter.

Hmm, it's internally threaded, so maybe not a good idea.

Thanks, Mikek
