5C collet stop for square and hex block

Another way to hold 1/2 x 3/8 part would be to buy 5c emergency soft collet and bore it to depth you want on the mill. If you bored it to .300 deep you would have a collet with a built in stop. And you can buy the collet on eBay for about 7 bucks shipped and have it in a few days. Then if you want you can keep the collet as is or rebore it to another size for a latter part. That is cheaper then buying a collet stop.

In the same vein, you could make a "top hat" split bushing to fit in a 3/4 collet. No need to buy anything.

One thing that hasn't been mentioned in all this is that if the OD of the parts has some variability, so will the length. It may not be an issue in this situation, but worth noting.

PT Doc, is that avatar a "Steal your Porsche"?

I picked up some shop made collet stop parts for almost no cost, seller did not know what they were. They are nice, fit very well, good work. Looking at them, they are quite simple to make.
