Hi All,
I was having a bit of a talk with Steve (Cedge) via PM's about graving.
No, it's nothing to do with digging a grave or raising the dead, but the way I make all the fancy 'doo dah's' for my engines.
Have you used a file for deburring a bit in the lathe, well that is graving in it's very basic form.
I have managed to find a u-tube vid that explains it in its basic form, but it does show the type of tool required.

Using this tool will allow you to make all sorts of shapes, cones, balls, tapers etc. Let your imagination run wild.
Rather than having a purpose made rest as in the vid, I put a round bar in my toolpost, it does take a lot longer to manoeuvre into position but it does the job. I also use my collet chuck because it is a lot safer than a normal chuck, but if you are very careful you won't get any grazed knuckles.
For really big bits I tend to rough out the basic shape first using normal cutting then finish off using this technique.
He also has a very good tip for drilling small centre holes on a lathe
