Today I made a new tool...and then promptly used it.

It's a mount to hold the dremel in the tool post of the lathe. I used a bandsaw to cut it out of 3/8" aluminum. I then mounted it in the 4-jaw chuck and bored the hole for the dremel. Next, I cut a slit and then drilled and tapped it for a allen head bolt so as to provide a means to clamp the dremel.
I am using it here to to form the radius around the lever shaft area. I put a rod into the chuck to allow me to pivot the part (The lathe is not running during this operation) I used a 1/8" carbide bur in the dremel.
I suspect I will be using this attachment for other purposes before this project is over. I intend to turn my own barrel plugs (as described in Howe's "The Modern Gunsmith"). I will use this arrangement to put an accurate ground finish on the plugs.
Next, I will be making the lever/shaft for the "stock stainless" . After this I will be setting this part aside for a while. I can't legally create the stock lug until I install the 16" barrel to the gun.
