Welp... worked on this a while tonight... here's what I have done so far...
Cut off a 3 inch piece from my 2 inch x ½ inch copper bar. Then I surfaced one side and the ends to get them trued up.
I printed out my drawing at work for a guide and cut it out. I then sprayed some 3M spray adheasive on the unmachined side (it was almost flat to begin with) and then put the paper guide on that side and pressed it down with another block of Acrylic. (blurry pic)
Then I drilled out my Jet Holes first... left approximately 1/32 of an inch of copper plate at the bottom.
Then I machined out the return water area.
Lastly, using my rotary table and a 1/16 inch ball nose endmill, I machined the groove for the o-ring or other seal.
Now I just have to drill and tap the holes for the bolts and do the acrylic parts.
I will add to this post when I get more...
