But, as usual, I was incorrect. My swivel base went when I traded my round column up for my Monster Mill (Induma), but if I ever get another swivel vice...
That vise is pretty massive and absorbs most of the energy from the hammer taps. It is possible to damage an indicator by tapping on it so you need to keep that in mind when using a hammer around one. Try to tap the part so it moves away from the indicator.
They are good, but I prefer an Indicol holder for the knee mill. It can do everything a holder mounted to the head can do, plus swing the indicator to center a hole or tram the head.

I have one.... in the drawer someplace. Index Milling Machine, so the quill is something like 4" diameter. Keep meaning to make a new quill clamp. :)
EDIT: 3.125" Quill (need to remember that to make an Indicol)

Index, now there's a name from the past. One of the shops I worked at had an Index and the Indicol from the Bridgeports wouldn't fit. It also had an issue where it wouldn't hold end mills tightly in the R8 collets. They would creep out on heavy cuts and ruin your day. I believe the table had a few tracks in it as well. Hopefully yours has a more substantial drawbar.

I was watching some u-tube videos the other day and ran across an idea that I am considering doing as well. Noga sells their holders sans the magnetic base if you desire to have the arms only. Someone drilled and tapped their Indicol clamp to accept the short Noga arms, instead of using the traditional Indicol rods and clamps. That sounds like having the best of both worlds to me.

It's a Index 555, built in 1966. It has a reground spindle, so R8.
I had some chatter with heavy cuts, once the quill was adjusted it is fine. No issue with pulling mills out of the collets. That would ruin my day!
Quill adjustment is a little unusual, as you have to loose on lock screw, adjust quill screw, then tighten lock screw. At least on the Y axis. On the X Axis it took a while to realize there is only one opening, but both a lock and tighten screw.
