Thanks for this! I actually read this thread and saw the counting jig at the end but plum missed the pin design...

further refinement to index spring index pin

john Lucas

What I really need is a way to use the index that comes with my Vicmarc chucks. I modified Don Bunce's idea some more. The pin can be rotated 90 degrees so it fits in the back or the side indexing. When I turn natural edge bowls and few other items that need to be sanded with the lathe off, it has always been a pain finding a way to lock the lathe spindle in various positions to be able to sand efficiently. This solves that problem and is very quick to reposition.

I used a 3/16 piece of steel. ground the end to a point and then ground off the point until the end fit into the holes in the back of the chuck very snug. then i found it also works in the side as well. unfortunately the holes are different sizes in my off brand vicmarc copies so I would have to make another rod to fit those but it only takes a few minutes to make one.

This very cool. I spent some time on Vermec's website today. They have an indexing arm that works with Vicmarc and Nova chucks. Your innovation is a lot less expensive (but it doesn't give as many index options).

Vermec's is almost twice as expensive as the Alisa
