Since then, I ve been persevering and things have been getting better. I ve discovered:
Life seems easier with HSS than carbide - its also cheaper too
I ve tried to be more religious with using the dead centre to hold the other end of the stock still which I think reduces chatter
I ve tried to keep the tool closer to the toolpost so that less is sticking out, again, aiming to reduce chatter.
I try and use the autofeed all the time as it gives a smoother pass over the surface
one odd thing I still can t track down is that facing cuts are way smoother thatn normal turning operations. I get that lovely crisp sound, no vibes through the machine and a nice clean trace of swarf. It could be that I m not very good with sharpening HSS yet and somehow whatever point I m acheiving is better for a facing cut than a regular turning operation.
