I'm a beginer with my lathe. I have been practicing facing, turning
and boring with good results.

My question is, how do you create a cure on a work piece. I want to
make dies for an air planishing hammer. The radius would be cut on the
face side. That is, instead of creating a flat face, which I can now
do, how do I create a small dome on the end. I want to create domes
that are almost flat to moderately curved.

Any tips and advice are greatly appreciated.

thanks,
Ed

It's known as "spherical turning," although, you're more
interested in radius turning. The two basic approaches are to
generate the radius with some type of pivoting toolholder or to trace
an existing radius with some type of sliding toolholder. Here are
some methods:

Another way to do this without special tooling is to
work the carriage handwheel together with the
cross-feed using a rounded tool. With a little
practice you can cut a reasonably smooth radius.
Finish with a file.
