Using a bushing die as a seating die ?

It would be nice to have a lathe !
I don't.

Some of the smaller bench top style are not all that pricey.

There are so many things you can do with even a smaller say 8 inch x 24 inch.

For smaller shaft style items you can often limp with a floor mounted drill press.
Rig up a bearing on the table to hold the off end of water you are trying to turn.
