Hi guys, here's another project that I wanted to share. This is a pic heavy post but wanted to share each process and op involved. The design came from the [mod edit for link] MakeItFromMetal website. I started out with a 1.5" x 2.5" x 6" piece of 1018 steel. The main block was then milled down flat and square to a finished size of 1.438"H x 2.438"W x 4.5" L.

Then the front and sides were face-milled at 45 degrees.

The rear slot was milled .250" x .750" deep. The front slot was milled at 45 degrees to .500" x 1.3265" deep, and the rear center slot was milled .625" x .625" deep.

The brass leadscrew was turned to an OAL of 1.838" x .375" with 3/8-16 2A threads on one end and 1/4-20 2B threads on the other end.

The knob was turned to 1.375" OD x .375" and then set up in the dividing head for (24) .040" grooves. This worked out to one groove per 15 degrees.

The brass jaw was milled down to .620"W x .620"H x 1.875"L and the 45 degree faces were milled top and bottom. Then the back was threaded 3/8-16 2B.

All parts were then degreased, cleaned with alcohol and the main block was blued with Van's Instant Gun Blue.
Contact parts were then lightly lubed and assembled.

Thanks for looking everybody. Stay safe.
