I use a blade to final trim phenolics
But phenolic is so hard, the blade wouldn't give way? You're talking about pen knife kind of blade or a special blade that is meant for it?![]()
Not sure what kind of set-up you have, but if it's just a simple homemade shaft spinner, your options are probably limited. A mill file and sand paper might get it done though.
The olfa knife with a black blade
Same as I use in all my tip jobs.
I use the lathe tools to get it trimmed close first
Leave it to someone who has a real lathe.
A HSS parting tool then a blade ought to do it.
I use a Taig radius cutting jig and an HSS cutter, works just fine.

No, I can't imagine hand-holding a sharp blade and cutting/shaping phenolic - I have a lathe and the jig mounts on the cross-slide.

Hmm okay. Wondering whether I'm able to DIY it.
Do correct me if I'm wrong, seems to me your tool is just a gauge for the shape?
Yes. I was addressing your blade stability issues you brought up.
I do have a auto tip shaper also, but I prefer the blade and rest.
