Tail support and mill stop combination

[Milt Able]

In making a tail support for my new 12 sided R8 collet block, I decided it might just as well double for a mill stop. I machined a 1.5" x 1" x 3" rectangular piece of mysterium steel to have a 60 degree conical tip to support extended work. I added a rod perpendicular through the back so that I could turn the assembly sideways and use the rod as a mill stop in other operations. The nuts on top and bottom of the "dead center" are to lock it into position. I cut 3/4" 16tpi so that one turn would give me 1/16 of an inch adjustments. The castle nut on top isn't for style points (though it did add a nice touch). It was the only other nut I could find in my pile that could be drilled and retapped to 16tpi.

Is the dead center also threaded or is it a slip fit?

It is threaded.

Is the base a plumbing flange?

I thought it was from a garage door, but unless it was attached to the spring, I am not sure. It was in my pile o' scraps.
