Modifying screw ends
« on: March 29, 2013, 06:33:25 PM »
Here's how I go about modifying the ends of small screws...



A brass 'collet' is made for each size of screw by tapping a short slug of brass with the required thread and then milling a small flat on the slug. The screw is then threaded through the collet and secured in place with a lock nut. The collet is then inserted into a steel tube and locked in place with a set screw.

The whole assembly is then stuck in a 5C collet on the lathe and the required work performed. (The picture shows a dog point put onto a 2-56 screw.)

The brass "collets" are easy to make and, over time, you'll acquire a collection of them to fit the screw sizes you use most frequently.  They're a handy use for the uselessly short bits left over from stock rods.

Well By God, that's nifty. You can swap that there thing end fer end and work on either end. 2 extra credit points there Marv.
