I remember seeing some of Jim's CG-45's and thinking to myself, "Dang, those air horns look tiny..." How are the mallard du fromage (duckbills ) attached? I'm thinking not like on a Mistral... JB

No, the bec de canard is like the USD 2 part bottom boxes. It doesn't go on the outside of the horn.

JB The original duckbill attachment is easier to access and service than on later regs. A light coat of simple rubber cement (like found in office supplies)can be applied and then just tied on with multiple wraps of synthetic thread. Not cotton. I'm not sure the cement is actually needed, but makes me feel safer since it seems all those exhaust horns I have seen lack a retaining ridge.

I finally got around to turning a punch for the pucks today. At the same time, while parting the punch off the rod, the tool seized and stalled the lathe. Apparently, this blew the controller board, and I have to send it off for repair. @#$%! How will I get by without my lathe for a week? Anyway, the puck is about 8.5mm, which is larger than a standard puck. I hacksawed the punch off the rod and punched out one from a bit of neoprene James sent me. It fit and does the job. I finished rebuilding two of the regs today. I had to replace the broken and brutalized exhaust horn screws with some brass screws I bought to make reproduction Broxton horn screws out of. Oddly, they are 10-32 tpi. You'd think they'd be metric, but these regulator bottom boxes seem to be copies of CG-45s, down to the threads! I'm pleased with the results of the two (pictured above somewhere). One is VG, the other VG/G. I'm looking forward to trying them out. I need to pick out a first stage to use (probably a Nemrod), make a first-to-second stage hose for them, and see if I can salvage a harness from the disgusting and reeking pile of 3 original back mount harnesses that came with the regs.

I think a bit of RTV will hold it on w/o having to resort to thread tying. Tying thread around these requires clever little monkey fingers, which I def do not possess! Maybe I could train my 1 year old grand-daughter?

Maybe I could train my 1 year old grand-daughter? The trick is to slide the thread under the duckbill, bring the loose end up with a lot of leader, and tie a figure-8 slip knot in it. Then go around the opposite direction and pull it tight a few times, and do a half-hitch or two around the leader. John

Huh. Maybe she could do that...

Have you thought to try a small micro zip tie ? With 2 pairs of needle nose pliers you can get them pretty tight.

I did try a small zip tie and didn't like it for some reason. I'll have to revisit that.

If you are looking for a more vintage move, you could use stainless wire and do a bread tie move. Copper wire would be easier to use but may corrode. SS wire can be picked up at any craft store in the flower arrangement/ jewelry making section. They also make a coated copper for flower arrangement that may work. I like the tie method better that using glue and adhesives. I have picked up regs to rebuild and seems the previous person used half a tube on them.

I've used a small amount of RTV to attach DAAM/RAM duckbills to the box so they can't get sucked back in or flop around. It holds so well you need to slice it away to remove the duckbill. I've no worry a DB glued on with RTV will come loose.
I know what you mean about "generous" application.

Looks like James is now in the Narghile owners club. I can't wait to see the innovations he comes up with for non-returns in these metal mps.

Are you going to print those labels?

Yes. But, I have to find a print shop to do them. I've used the on-line printers in the past for vinyl labels, but most don't do foil. I also have the Scuba Deluxe labels to get done in foil. I'll need to spend some time looking for a local shop or an on-line service.

I contacted an on-line print shop today, hoping to find someone who will print a few labels. I got someone I thought might work out, but she shied away from making labels for scuba regulators. Poop.
