A while back I purchased a SuperNova2 chuck and a fairly complete set of jaws. A problem I ran into is that the coverage of tenon sizes is not continuous (definition: tenon to me is the stub of wood that the chuck contracts onto to hold the piece).
For example, if you make the tenon 4", the 100mm jaws are too small at max extension (max size about 3.89"), and the 130mm jaws will not contract down to 4" (min size is about 4.25"). The same thing seems to be true for a tenon of about 3".
Now, I guess I could keep a table of the max and min sizes in the shop and only make tenons that are supported, but that seems like a very poor design of the chuck. I should be able to make a tenon of any size from the smallest supported by the smallest jaws, to the max size supported by the largest jaws - the support should be continuous across the jaws.
I'm PO'ed enough that I'm going to sell the SuperNova2 but I don't want to buy another brand that has the same problem. Any recommendations?
Or am I missing something?
