Re: Re: Re: Modifying Diamond Pacific Genie water system

Hi again Judy,

The primary reason I set the valves back behind the wheel centers was to help insure clearance should I decide to mount 8" wheels on the machine, which are a close fit under the existing cowl.

I also had the idea that setting the valves back might help better distribute the water over the wheel surface before it rotates around to the work position and help reduce spray. But my general impression is that apart from interference considerations, the valve position is not critical and the wheels are going to get wet (and spray) regardless.

I normally open just one valve at a time as I move from wheel to wheel, but the system depicted in the article can deliver more than enough flow to simultaneously get all six wheels slinging wet.

I like to run my wheels very wet to transport away heat and swarf, wetter than I was ever able to get them using an air driven "spitter". The wetter you run your wheels, the more spray they are going to sling. So if you like your wheels as wet as I do, you'll also need to do some engineering on spray catchers. I haven't written up the spray catchers yet, but you can see a picture showing my solution to the spray issue at the end of the article. The green spray arrestor flaps are cut from scrub pads, which are positioned to leave about an 1/8" gap between the inside lower edge of the flap and the wheel surface.

During extended cabbing sessions I wear a nice shop apron my wife sewed up from duck cloth to catch what residual spray does escape and keep my shirt completely dry. I've been using the set-up depicted in the article for over a year now and am a happy cabber with it. The one luxury embellishment I have yet to engineer and add is a water heater in the sump, so the water is not so cold on my pinkies...
