Michael,
I have a Grizzly 8688 (7x12). My first chuck
upgrade was an LMS 5"- 4 jaw, holy smokers! I switched to a 4"- 3 jaw, seldom
ever comes off the lathe. Foe me the 4' has worked out lots better. Kept the 5"
though, just in case....hmmmmm.

jaw independent chuck - 1st look
Well
I finally got around to mounting the LMS 5 inch 4 jaw independent chuck on the
Micromark 7x16.
?
Here
are a couple of pictures:

My
first thoughts now that I have it are that maybe the 5 inch is a bit much for
a 7x lathe. While the Micromark motor has no problem spinning it up, the added
mass of the 5 inch takes a while to spin down?to a stop.
?
The
5 inch weighs in around 14 pounds with the required?adapter
plate.
The
standard 3 inch weighs in at 3.25 pounds.
?
IT
IS POSSIBLE to extend the jaws out far enough so that they will hit the bed. A
little care will need to be taken so this does not happen. I opened it up so
it could hold a piece around 2.75 inch in diameter and the jaws had a
comfortable clearance over the bed. This was with the jaws in the position as
in the photos, I haven't turned the jaws around yet to take any measurements
in that configuration.
?
I'm
wondering now if maybe a 4 inch chuck would have been better.
