Well the brass or bronze is the relatively spendy stuff but then again a machine shop will have some shorts lying around for a good price. Maybe 5 - 10 bucks for that. The stainless would be a couple of bucks.

>> Alistair, this is an elegant and seemingly very good redesign. However, most of us lack machine shops, and even fewer of us have your talents. I realize that some folks with lots of time and effort can develop talents, but remember, I'm the guy who once twisted off the bolt that held the waterpump housing onto the engine of a 1966 Ford Falcon.
