I'll expand on Chuck's question and ask the experienced turners here - "What turning tools should a turner have?"
I'm an occasional turner who turns mostly for furniture (spindle turning) and a few bowls and boxes (not hollow forms).
I have the following:
1" roughing gouge
1" round nose scraper
5/8" bowl gouge
1/2" spindle gouge
I manage to get everything done that I want to do but are there any other tools I would find useful?
Go into the world and do well. But more importantly, go into the world and do good.
