And this afternoon started in on the next batch of parts for the check valves - these will become the inlets/outlets on the outer cap plates, connecting the check valves to the horizontal pipes. The pipes will have Tees (normal plumbing ones, using household copper tube) with flat plates soldered to the T to bolt to these pieces. These pieces will be bored down the center, not all the way through though, with an opening on the side to interface with the T.

Very nice pile of parts there, Chris!  Looking forward to seeing them all come together! :)   :popcorn: :popcorn:

When the pressurised side of a simple water system leaks,  we can tap  :killcomputer: the check valve ball into it's seat........to get a seal  :ThumbsUp:
 
When a complex water system with multiple check valves leaks, and each valve with multiple check elements  :Doh:  :facepalm:  :shrug:  :lolb:

Good luck  :ROFL:

Very true. On the original machines there were over a thousand valves to get the volume, if a few stuck they would not lise that much. On my model there are four per section, 48 total. Much more chance for failure than ony Weir pump with two. At least in this case if one somehow sticks it will still pump some, good enough for demos, till I can bribe a shop elf to go in there with a little hammer.

Thanks Roger!    Been toiling away on drilling/tapping the holes in the inlet/outlet blocks, doing a couple blocks at a time then going off to do other things. Not quite as bad as doing crawler tracks!

Hoo boy, could be a wild time in the old town tonight! I'd get the shop elves on the compressor / air needle scalers tomorrow, to clean up silver solder flux or something. It's an effective hangover cure....... :Lol:

Remember, deaf shop elves don't hear beer delivery trucks!  :o

Pump parts progress looks great Chris!  :ThumbsUp: :ThumbsUp: :ThumbsUp: :popcorn: :popcorn: :popcorn:

Woke the shop elves early today and sent them into the shop to finish dilling/boring/tapping out all the pieces for the inlets/outlets on the check valve arrays...

The pile o parts, blocks ready for silver soldering the side tabs to:

After soldering, the tabs and blocks will be drilled through the side for the water and mounting screws. The blocks will be screwed to the round caps/plates with some thin rubber gasket for a seal.

Yesterday saw the side tabes silver soldered onto the connector blocks for the check valves. Today I bored the holes in the sides, and skimmed the face where they will meet the flanges on the pipes.

Bore, skim, repeat...

Then, on todays episode of Confuse-An-Elf, they are trying to figure out why the local bees sent them a stack of their poker chips!

These are the blanks for the flanges that will be soldered to the plumbing Tee's - did not have any flat stock the right width, so I took a length of hex bar that has been sitting on the rack a few years waiting for a use, and cut some chips off the end. They will be bored to fit on the tees, soldered on, then the top/bottom edges will be milled off to form the flanges.

You must grow some BIG bees in that area if those are their poker chips.
