started turning acrylics with negative rake tools and everything was going good. Now as I'm cutting, I get to about the middle of the blank and it starts chattering and gets worse as I move toward the tailstock. Any suggestions please?
Thank you. Ill definitely give it a tryAre you sure that the tool is level or tipped up in the back some? If you have the tool so the handle is down lower that the head, you have lost the negative rake aspect.....just a thought...
It improves and totally goes away the closer I get to the headstock. Bought a new mandrel and tried but same problemWelcome to the forum.
Depending upon your set up it maybe flexing of the mandrel or slightly too loose. Does it 8mprove if the cut the other way towards the headstock?
Mandrel with knurled nutWhat type of mandrel are you using?

Had the same experience - getting closer to the tailstock increased the chatter. The live centre in the tailstock wasn't too tight against the end of the mandrel BUT .... I forgot to tighten the set screw onto the quill. After tightening the chatter went away immediately - hope this works for you.started turning acrylics with negative rake tools and everything was going good.
