That was the original project were I designed a second stage to be used with the Voit Titan. Later on I modified that second stage into what eventually became the HPR. The Pegasus in some ways provided the original test prototypes for the HPR, but there are several difference.
The thread pitch for the Voit and US Divers are different. If you were able to thread an HPR into a Voit Titan, you have damaged the threads (probably on both mating parts).
Herman did most of the machining for this project and he may be able to fix the thread damage.
The US Divers (Conshelf type) first stage balancing chamber can be adapted for the Titan and other Voit regulators, but it does require some modifications. I wrote how to do it somewhere under one of the single hose discussions. I will try to find the thread later and post a link.
Hey Luis,
I already assumed that the HPR might not pitch in right as I attempted to mate an HPR with my Trieste about 2 months ago. That said and as an engineer your aren't going to like this, I was willing to sacrifice an HPR body to the Voit Scuba Gods and using a lot of silicon grease,
gently BRUT FORCED the HPR body into the Titan body. The endstate came out on my side
this time. The interior pitch on the Titan body, due to its mass and possibly temper was able to retain its original pitch and the HPR body was "adjusted" to its new matrix by way of it not having the mass and possibly the temper of the main reg body. This was verified simply by re-inserting the original Titan "over-pressure" seat/valve casing back into the reg body. No change or binding was noticed. Thus, even though the HPR is now adjusted/re-pitched and only usable for either a Titan or Trieste, the endstate was achieved. The HPR body will fully seat into the main reg body and functionality is perfect. As said previously, my main issue is in the 1st stage and Antique D gave me some things to recheck. I'll let you know how this turns out. I will check out the "Pegasus Project" as well. Thanks for all the information guys.
As a side-bar, does anyone else notice that many of the projects and regs we get in to revolve around the myths of Ulysses, Jason or Perseus and Andromeda with regards to regulator names (Kraken, Pegasus, Titan, Poseidon, Calypso, Argonaut?????)
Thanks, Russ
