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.
