I bought a couple of packs of machined PCB turrets but haven't found the right tool or technique to support them when setting the tail. The turrets collapse when I try to set the rivet.
I was expecting the outside diameter of the wire supports to be smaller than the base OD to allow a sleeve tool to transfer the reaction force to the base, but these ones have an equal OD.
For scale, the stem at the bottom is 2mm long.
Does anyone know of the correct tool for this type of turret?

Thanks George.
I was expecting to be able to use a tool like this:
But they need to fit over the turret to the base like these:
Thinking maybe I need to buy more turrets..

The world is full of things which look like turrets, but aren't. Even if you overcome that dysfunctional design, will solder stick to it? I recall one of the very major tube-parts supply stores was shipping "turrets" which did not take solder. Dirty metal? Embedded lubricant? Bad alloy?
Hoffman Amplifiers is notorious for his solidly-built amplifiers and the parts store he grew out of that business. He's winding down the store, but he still gets these turrets custom for him, and has customers who will rattle his door if they can't solder.
EDIT- I didn't notice you are 10K+ miles away from Hoffman. And we know from another discussion that book-mail US to AUS is really terrible this year. Not to mention tax upheavals.

You are not fully showing the stem end, is it hollow? (so expected to expand like a hollow rivet) or solid? (pressure fit in a slightly undersized board hole)
If you expect to expand a solid stem, such pressure will certainly crush the full turret.
+1 on checking it´s solderable.
Almost impossible if stainless steel and quite hard on some nickel plating types.
YMMV

The bottom of the stem is solid. The turret is hollow.
Definitely a good idea to check solderability.
They are brass, so I thought they would set like a solid rivet.
Can I ask what turrets you use?

Just thinking aloud:
1) the hollow is not designed to expand, but to take a component leg (or naked solid wire) in, as an alternative to wrapping it around the turret, meaning it´s not a mounting feature.
2) the stem pressure fits in a slightly undersized hole, use a tool similar to the one in post #6, not pushing a shoulder you don´t have, but turret top.
3) I hate turrets and much prefer hollow rivets "Fender style"
