Yes I did have a look over your site and some of the comments were very
interesting. I have three copies of his patents (1,730,336; 1,730,337;
1,941,593) plus a copy of an article from an "unknown" publication.
The thing I wanted to get sorted before I start assembling was the types of
parts needed (was talking to a neighbour with some engineering experience
and made some queries and suggestions)....I will explain.
First off, the foot valve is no problem for it's a simple foot valve, nor is
the pipe a problem. The short-stoke piston, however was the first question.
On your site someone mentioned using a piezoelectric hammer, any updates on
this would be great.
Second part (going by the picture) is the outlet valve which my neighbour
rightly commented could be replaced by a simple valve to just let the water
out when it pulsed upwards. Just checking, however, just incase there was
something else it was doing.
Thanks,
Matthew Redmond
