Nice work! I have a couple new ones coming if a few months. One is almost complete, the other is more in my head than anything but it looks promising. If all goes well, I will show the first one off after some sea trials on Bonaire in Feb.

When would you like to try it? I'm going to test it in the pool first, along with my Dacor conversion and a couple others. Jim Steele's invited me to his class so I can use the deep pool. Hopefully it will be soon.

Got the DBE installed and the regulator is ready to test. Working on a label.

Did the pool test with the Titan II in Mistral cans. I have dived this regulator in FX cans before, in Monterey, and it worked well. During the pool test, after working well for a few minutes, then suffered an IP creep problem that took the IP up to 200 psi and blew the second stage wide open. Luckily, it was in the pool and not at 60fow in the ocean. The HP seat is a NOS original, and it failed in under a couple hours of use.
I ordered some new blue MR12 seats and Conshelf pins to replace the OEM parts. I'm tossing out any spare OEM seats I have and replacing all the installed ones...

PY, I remember someone not too long ago telling me that I was being "overly dramatic" when I said that these seat can literally blow themselves apart The material used on these does not age at all well: I think we can say that they defiantly have a half-life: en.wikipedia.org/wiki/Half-lifeI'm glad you're safe JB

Several people have mentioned this problem to me, saying they've had the soft material in OEM seats crumble away. My HP seat sure did. After inspecting it, I'm surprised it held the IP to 200 psi with the amount of surface that was missing.

Got a couple new seats, installed one and IP is holding fine. The Titan III is back in bi'niss.

Got some parts coming from Rob and Bill T to get all my Titan IIs and Conshelfs working. I think I'm all caught up?
I've got a couple orphan Mistral top cans, so I'm thinking about making a second Conshelf DH mod with the second stage hole in the right place for the Dacor splitter.
Another thing coming up is the long awaited and much ruminated-on (by me) Dacor Oly with a self-contained, screw-in Sportsways type second stage, featuring an adjustable seat. It's gonna be close, as the tolerances are very small. I really want to make this work.....

Titan II is fixed with a new seat, holding beautifully at 135 IP. I've reworked the levers in recent months, making them shorter and centered, with the legit curl bend on the tips. This is a bit over-kill but it looks right. I'd do the double bend on the stage body end, but that's just getting ridiculous. Vs this. And the ultimate pita:

I'm working on a better way (at least better than the way I did it last time) to make that dratted double bend at the poppet end of my levers. Voit designers did it for a reason, maybe to raise the lever up higher to keep things from interfering with each other or to gain a bit of poppet movement. Not sure, but they didn't do it for fun.
I have a new one in the works, but it was just too hot today to spend much time at the machinery. I used my new drillpress setup and a hole saw to cut the IP adjuster clearance out of a piece of scrap stainless, filed, ground, and hacksawed the new lever shape partially, then gave up.
Ugh. Back to 90 degrees outside and way more in the garage. I didn't even go for my daily hike in the woods.

Did a bit more work on the lever blank and new second stage. It's even hotter today so I didn't last long. Soldering the second stage did me in. I think I've got the double bend figured out. it needs some refinement, but it worked: I'll do a lot of cleanup on both parts and post the results when it's done.

PY, we had 106-F here today! So, I'm thinking what if you put a 90 bend in the ends, then, use a flat bar to hold the levers down butted up against the 90, then, butt a metal rod up against that and form your ends over the rod. Anyway, that's how I'd do it JB
