As promised, here's the first picture's of my new block. Once it's entirely done the shiney aluminum portion will be shiney Black Aluminum!
Following a tradition of using state of the art, exotic materials in my projects,this thing comes in as a "10".
The body is fully machined (from billet) 6061T-6 with a 3/4-16 stainless helicoil supporting the main shaft. That main shaft is Inconel 625 hollowed somewhat to provide an internal oil reserve. The hanger is inconel as well.The wheel is Aluminum Bronze with an oilite center bearing. 6/12 Nylon thrust washers support both sides of the wheel and of course o-rings seal everything on both ends too. The block is 9 inches long overall and the wheel is 3 1/2 inch O.D. I think it safe to say this thing would rate in the 1800lb range which is way more than I'll ever need pulling them 4 pots!
I will build these for anyone who is interested and will only charge time and material. uh, I guess that's the cavieat, as time and material for this baby = $1150.00
