After much searching and many purchases I have found a suitable replacement for the Chouinard Sewing Kit Collet Chuck. I discovered that they were called Pin Vices.
In the below picture you see the four Pin Vices I ordered for comparisons with ruler and coins for sizing. 3rd from the left is the Mini Hex Chuck, 4th is the Micro Drill Chuck. The drill bit is 3/32". Clicking on the items will take you to the Amazon web page where they were ordered.
I decided on the 2nd from the left for several reasons.
I also chose to include the larger collet with my
emergency sewing kit as it can be tightened pretty small.
I tried to cut the bar. But after it was cut the remaining piece just pulled out; resulting in the two pieces to the left and below the quarter.
Collet ends have 4 prongs. It would have been better to have three prongs like drills. They could all be tightened until the prongs touch.
Here is the packaging for the one I choose. The long bar had already been removed..
I hollowed the center to allow for long needles with a 3/32" drill bit. Because there was already a hole 1/4" deep from the removal of the bar, it was a lot easier to drill out by hand. The pre-existing side hole is also 3/32".
Here are the 3 pieces I will include in my emergency sewing kit. With the rounded blunt top (at the bottom by the 2 5/8" mark) one could use a rock to pound an awl needle thru hard material like thick leather.
