I am working on REV 3.0 right now. have the peice in the machine and should be done by the time i am half way through typing this.
This time I am using 1/8" thick C110 copper for the base and modifing the Pyrmid Pin array I had in REV 2.0. The pins are taller and the channels go deeper.
I am also making a Nozzel for this one today. This is my attemp to go after the White Water. Look for a thread called REV 3.0 This weekend.
Only thing I should have to do when I get home is thread the barb holes and seal it up.
