Ok, here is a better picture of the pressure drop test. I did drill and tap the barbs in, that was interesting...I had to clamp it to the side of my drill press table because the block is so long..



Still lots to do, I need to drill and tap all the holes for the second block, and that's four bit changes per hole, because I like perfect countersinks. I end up drilling and tapping a hole on each corner after clamping right through the block. Then I have to drill once clear through both pieces for the tap size, the change the bit to the bolt OD just through the delrin, then I cange again to a 3/16" endmill for the countersink. Then I move on to the next hole.

When I'm all done with that, I get to start tapping just the copper base in each one again in the drill press. Very time consuming...

After that's done I need to drill and tap the barbs for the second block, then I need to cut all the bolts to length, then I can start finishing the tops of the blocks, then take the blocks all apart and bead blast them, finally seal and assemble them, drill the bolt holes for mounting the two blocks together, and finally finishing the base.

Still a ways to go..
