Scroll engagement half or more of the teeth engaged, on an 8" chuck that is 3-4 teeth.
On a 1236 lathe with an 8" chuck, you may be more limited also due to limited swing of the lathe. As an everyday chuck on this size lathe I would be happier using a 6" scroll, switching to a 4J independent for larger diameter or irregular work.
Extending the outer jaws past the edge of the chuck - how far before unsafe?
I have a 6" four jaw chuck for my G0752/G0602. Just bought an 8" diameter disc 0.8" thick of 6061 to make a fixture plate for a recently purchased rotary table. How many threads of engagement should I have in each jaw? The jaws look far enough out that I'm wondering how safe it is. Obviously...
