Spike,
Well I was planning on building the Karebill style generator first , but unfortunately my domestic duties did not allow for any time this weekend.
On another note, it's back to the drawing board on the manifold design. As I feared the tolerances were too tight for machining and it failed miserably. I did like the way you used the PVC tee's to make your manifold and think I will be pursuing the same route.
I will keep you updated.
