I didn't look at the flyer before. I have a Palmgren milling attachment, and your easiest option for vertical mounting would be to clamp the rotary table onto the table
of your mill the same way it attaches to a toolpost, using a?T-nut, 3/8" bolt and a bar from the usual clamping kit.? This would hold it as sturdily as it was intended to be
on a lathe. (Which is not very).
But I suspect you'll mostly use it horizontally. For that I would remove the Palmgren mount and its lead screw and fasten the rotary table to a plate large enough to
clamp onto the milling machine table with the standard clamping kit.?
For this you'll have to make four threaded holes in the back of the rotary table for screws. I'd probably use socket head cap screws and either recess them or arrange
for them to fall where they? don't hit the rails of the milling machine table. You should make these easily removable because you'll have to put the Palmgren attachment
back on to use it vertically again.
But if I were doing this, I would still mount it vertically on an angle plate, using the same four screws. I disagree that angle plates are too big. Cheap Chinese ones
are made of cast iron and come in different sizes, and if necessary you can saw one down so it isn't any bigger than the? rotary table.? This would be massively more rigid
than that Palmgren attachment.?

As the flier in the add shows it was made to mount on the toolpost of a lathe.
I could mount it vertically with a couple of 123 blocks but not very steady.
If I put it on a large angle plate I would not have enough room between it
and the mill spindle.
I agree that this is not going to be a super rigid mount.
The only "true" surface on the back is the dovetail.
I'll have to take it apart to see how thick the unmachined part of the back is.
If I had not gotten it so cheap it would not worth all this fiddle'n.
