Hi Mike 

I did my rotatable slip rings on the cheap they lasted 9 
Years before the high winds dealt to my pole.. 
It depend on how much money you want to spend . this is how I did my 50 MM 
water pipe but mine was a 6.5 mtr length on top of a 6 mtr 
wind mill tower.. On top of that was a Hornet TB 750 Tri-bander !!! 
I cut 1 mtr of the length and threaded both then used a socket to rejoin 
them I the got a 50mm flange end took to it with a lathe 
so that it fitted over the 50mm pipe the socket 1 mtr down stopped it 
sliding down the pipe . 
I did a similar thing at 3 mtrs up but I didn't cut the pipe I lathed out a 
second flange and portioned this at 3 mtrs and then welded it there 
in place as a stop , I then used ( I think a 70mm socket that I welded 3 
eyes to it for the 1/4 wire rope ) slid that down on top of the welded 
flange and this was my second bearing ,, 
I think the whole lot cost me about 30 NZ dollars back then for the Sockets 
and Flanges . 
Hope this helps 
73 Phillip

I am looking for a couple of guy rings that we can use to guy a couple 
of sticks of 20ft water pipe in J6 and still be able to rotate them by 
hand. Our host is still securing the pipe I asked for 1.5 inch to 2 
inch do pipe. 
I have seen the slip rings for the fiberglass poles and that might work 
with some sort of support underneath. 
Ideas and sources would be appreciated.
