do know the jaws are numbered and they only go in a
certain slot. The jaws have discernible numbers, but the
slots in the chuck only show where number 1 jaw goes. The
other two are at best, vague. When installing the jaws
sequentially into the scroll thread does # 1 go first
followed by #2, etc. or do they start at the same time?
With all jaws out, crank the pinions until the outer scroll
tooth approaches slot one.? Back off a bit.? Insert jaw #1,
hold against the scroll and advance the pinion until it
grabs jaw 1.? Advance pinion until scroll tooth approaches
next slot, that is #2. Insert jaw # 2, repeat for next slot
and jaw # 3.? Really, there is no need to have slots 2 and 3
numbered, they just follow after slot #1.? And, the only
reason to have slot 1 marked is to make sure you have the
jaws in the same slots they were in when the initial jaw
grinding was done.
