Pin vise: two versions

[morsa]

Back in 2013 (photos keep track of date) I made this pin vise with a small drill chuck.





In 2007, I made another pin vise with a Mini drill chuck









and with a set of drill Chuck collet bits





In addition to being used as a pin vise, the mini drill chuck can function as a rotary tool

Adding a handle to the type shown in your first picture can improve its versatility. Especially so if you use the tool to grind points on rods using a bench mounted grinder.

Improvements to a pin vise

Thanks, mklotz. Such a handle could be helpful in some tasks, although for grinding points on cylindrical rods, I prefer to mount them on the cordless drill, and for grinding or polishing irregular pieces I like to use hand vises.



By de way, I forgot to mention another pin vise similar to the first one.





These pin vises are very useful because in addition to a basic set of bits, a special tool can be made at any time and it is not necessary to have a handle for each tool.
