Any tips on turning brittle wood. The ends of my carbonized bamboo take exception to being turned. Are the carbide tools I’m using helping or hurting?
I managed to remove a lot of material with a rasp but at some point will have to turn the ends that chunk off. thought about applying ca glue to stabilize the ends.
Is faster RPM’s better or worst?

Right or wrong, I’d try higher speed. And for sure I’d have the sharpest tools possible. Carbide might not be the best way to go.

Yea, put the carbide away. It’s great for lasting forever but it just doesn’t take an edge like HSS. Use HSS tools, keep them sharp and crank the speed up.

Stabilize with hardener or ca glue.

Yes use the ca and a skew to get a clean cut

I finally completed the carbonized wood but hit a snag on the fossilized wood. It had to be sanded to shape with progressive sanding. That project is on hold for now. CA glue is a great tool in the shop.

I was going to suggest sanding. If you have an oscillating multi-tool or even a small angle grinder you can prop it against the tool rest and turn the work at low speed and sand down the high spots fairly quickly.
