Floating reamer holders ?

Make one. Here is what I made, a rookie project, a child's play for you guys.
A few months ago I made a reamer pusher, but I did not like the idea of holding the reamer with one hand while cranking the tail stock, so Iade a coupled pusher, more like a floating reamer holder. The reamer holder will float at least 0.030 in all directions except fore and aft, it moves more, but no ill effect. Inside the pocket of the pusher is a 1/2 inch ball bearing that floats in the 0.530 hole and it is sandwiched between 2 flat surfaces, the floating .4375 stem from the holder and the stationary pusher stem.
Except for the solid pusher stem that is clamped in the collet, and the 7/16 reamer holder stem, both of which I turned down from a solid steel rod, the material used was a short .224 barrel stub. I made use of every bit of the material. I had to think through on what all machining I need to do on each set up so I don't waste any material and still have enough material left to chuck up on the next step.
I have no idea how well it will work long term, I've only chambered 8 barrels with it. As far as strength and durability there was no effort done to take that into consideration, I was just trying to see if I could do it and whether the concept is feasible. I learned a lot, my first internal threading job ever, I am quite pleased that I was able to screw the two sections together.
If this one holds up well, I may sell my JGS floating reamer holder. Though the JGS is a massive piece, my observation it does not float enough.
The pictures tell the tale.

I have a mt2 bald eagle reamer holder but its a real bald eagle (gebhardt). Get a #3 set and get a 2mt thread adapter and put the full radius on the end to match the #3. All its gotta do is push
