I used a Yaesu Thrust bearing to do what you described. I fitted it upside
down and used the four bolts that hold the bearing shells together to fit a
small plate by which to connect the "inverted V's" to.
It worked for years okay and was cheap and easy. Only changed the system
when I got a 70 foot tower and had no need.
See link above for bearing.

Subject: [TowerTalk] Inverted vee mounted above HF Yagi
Hi Guys
I have a standard 60ft Versatower with a Yaesu G-1000 and bearing mounted at
the top, and just above this I have a Cushcraft A3WS (pic on QRZ). I want to
extend the stub mast about 20ft above the A3WS to support the centre of a
160/80/40 trapped inverted vee. I'm looking for some type of mount that will
allow me to mount the centre of the inverted vee at the top of the stub mast
and remain fixed whilst the stub mast rotates. Ideas/advice would be great.
73, Jack G8DX
