Turning Eccentric

[Imadgets]

OK I admit I've always been eccentric.
But I would like some advice on turning eccentric. (On the mini Lathe)

I am turning the outside of an off centered brass cylinder such that only half of the revolution is making a cut. This is for my beginner elmers wobbler engine project.
I am getting heaps of chatter.

I have adjusted the cross slide nut to remove pretty much all backlash.
Any advice?
Fast or slow speed?
Face or turn the bulk of the cut?
Cutting depth?
etc

Thanks alot

Slow speed
Turn, dont face
Try .010 per pass.

Sharp tool! No lube

And Patience!

There's nothing worse than roughing out an eccentric quickly to find it's moved and you have to
start all over again.
