Welp... got the other 18 jets cut and smoothed out... flared and installed.
Did a test run in the sink from my filtered water faucet... only 12 Gallons a minute flow...
As you can see (sorta blurry) the center jets are indeed getting the most pressure... BUT, this is without the "cups".
Other views... Jets installed...
Inlet and Outlets installed and the two acrylic sections glued together.
Finally... top section sitting on the baseplate with silicon II tub and tile sealant drying. I filled in that 1/16" channel with it and am just letting the weight of the top spread it. When it's cured 12 hours, I will put the screws in to clamp it down and seal it.
That's all for tonight... and BTW... I don't wanna risk my P4 by prying off the IHS... but, yeah, I know it can be done.
Again, this is just a test block anyway.
