I replaced the Conshelf first stage with another after fooling around too long with the creepy one. The "new" one holds IP, so I set IP to 80 just for the first pressure test and gave it the gas! It works!
Now I need to turn a new second stage cap that will also be the body to can retainer, then drill some jets that go in the right direction. A new lever needs to be made as well, and then it gets a diaphragm and cover on it to see how it breathes!

I made a new second stage cap and found a lever that works fine for now, slapped a diaphragm in it and covered it with a 50 Fathom can for the test. It breathes pretty great, even at 80 psig IP. I'll bump that up to 130 or so when I trust the LP pipe fittings! All's it needs now is a new lever, new better can gaskets, and to be prettified a bit! I don't think it looks too kludged together, given what it is....

OK, got a new idea to eliminate the tube, plus add LP ports. Heh. And it'll look better. And, it'll be way less kludgier. Maybe even so less it might look like it came out of a factory. And I won't be afraid it'll explode.
Will do some machining...

Soooo, I did some machining today. I ended up ruining a nice part that I tried to mod for my tube eliminator/LP port multiplier, by not realizing exactly what needs to stay intact in order for it to work. But, all was not in vain. I learned a coupla things and got a coupla new ideas. Besides, it isn't a rare or expensive part, so whatevs. I went to school on the thing after its demise and did some experimental cuts on it just to see what happens, so's not to wreck the next one. I'm being purposefully vague here, 'cause I'm not revealing what I'm doing until the.... well, reveal. If it works, in other words. Which I'm not entirely certain of. More parts are at risk, as more machining is required! CJ is prolly wondering what Vance is going to end up with at the culmination of this experimental mash-up of single and double hose parts, mods to irreplaceable vintage parts, accessories being adapted to uses never intended, ruined parts and materials in the slag heap, and other crazy-a** ideas no one even cares about. And, then, what he'll do with it when it's finished.... So wonders Vance. Never stopped me before.

Thanks, Mark!
Still got some details to work out, but it WILL work!

Here's some progress. Still not the lever that will be used:

That's pretty slick. I assume a couple of orings to keep it sealed and allow for bolt rotation.

Yes, it's regular 3 way splitter with a custom length through-bolt and a custom hard seat carrier. I was hoping to make this with slightly modified off the shelf parts, but wasn't able to due to my first use of the tube for LP supply.
Since I had not begun with the splitter, the second stage body hole in the can is too far away to use the stock through-bolt. I also made the second stage body because it was easier to get the dimensions perfect than by modding the Sportsways body. Now that I have a sample, I may mod a SW body for it so there is an adjustable hard seat.
Next time I take it apart I'll take pics of all the parts.

Pay close attention to the tolerances and oring durometer on that part otherwise oring extrusion could be an issue.

I just ran into this very interesting regulator, the Mares Air King S, on Adair's CG45 site. It has the tube LP feed system, but used a tilt valve. It also has a very interesting exhaust system that I find fascinating. If you are interested in checking it out on CG45's site, here's the URL: www.cg-45.com/regulators/Mares/01/index.shtml
