Mike,
To use the lathe module in LazyCam you will need a pro license and that would give you Gcode for the finished profile.
Lazy Turn, in current state, will not do a finish pass yet. You can however get the code for a rough / finish pass, and with some hand work have a smooth surface.
Can you provide a dimensioned sketch of the handle and post it?
Then maybe someone wil quickly draw it in CAD and generate the Gcode for you.
Just a heads up on the LT and LC software.
I know folks in here are using free / shareware CAD programs, I don't use them, so surely you will get a recomendation.
Have fun during the learning curve,
RICH
