Ace, I am like you, the spray finishes I use, I spray them off the lathe. Most of the finishes I do on the lathe are friction finish.
Hey Ace...........you have raised a question I have never given a thought. When I had my lathe, the finish was all friction applied. I hope others really chime in here on their favorites ways to apply finish........and even the finish preferences.
I am getting closer and closer to the purchase of a lathe.
Waterlox. You can wipe it on while still on the lathe.
Other finishes you might be able to use the slowest speed and not throw off the finish.
Just wondering...any of you guys use spray cans of Shellac or Lacquer and spray on the lathe???????
