I recently upgraded to a beall chuck and have a few questions.
First here is my basic equipment:
Jet 1220
60* live center
Beall Chuck
1/4 and 5/16 collets
8" "A" and "B" mandrel rods from Joe C
Now to my questions:
1. Should I be using the spanner wrench to tighten the collets to the mandrel rods? The reason for this question is that when I loosen the nut on the chuck after turning the pen the mandrel rod "Pops" to the right after the nut is loose. Is this normal or am I in some way over tightening it?
2. I have just recently purchased some kits that require me to use the "B" rods and I am experiencing some wobble when I turn the lathe on. I know that wobble is not a technical term, however I am not set up to accurately measure run out. To further define what "wobble" means I would describe what I am experiencing - after installing the 5/16 collet and a brand new mandrel rod, I tighten the chuck nut using the spanner wrench. When I turn the lathe on, 1800 rpm, I notice a slight wobble are the end of the mandrel rod. In order to eliminate possible causes I placed another new mandrel rod and check it again with the same results. I then reinstalled the 1/4" collet and "A" rod and the problem disappeared.
Does anyone have any suggestions or comments on either question.
