Hi Pete,
BTW, considering that with the installation of the HPR and the Phoenix you only have 6 original parts (7 if you include the original label), IMO it is kind of a stretch to still call it a DA.
In any case, the moment you install the Phoenix it became a Royal (a balanced regulator).
I have found that if you push the washer tight against the second stage body and then tighten the screw, it holds the body good enough. There is a little bit of play since the washer is round, but that should not be an issue.
If the second stage ever rotated a bit, the back of the lever should be high enough that it should not interfere with the first stage adjustment screw. With the prototypes I was using plastic rivets with a long back that I had to cut, but the production plastic buttons have a very short back piece.
Macado, if a single washer is not tall enough, you can use two washers under the head of the screw. But, I am thinking that you may have unscrewed the second stage more than 180 degrees to line up the venturi nozzle.
Bryan and I have been talking about a new square washer to hold the second stage tight and avoid any play. The hole in the washer will have the same clearance that the existing hole so that you can push the washer tight against the second stage body, but the square washer will have a flat long edge to firmly hold the second stage.
The washer will be thick enough to provide a good contact surface even if the second stage body is back out a full turn or more.
As I mentioned, I didn’t find the little side to side play (of the second stage body) to be an issue and it should never cause any problems, but I can understand the concern.
Bryan should have the new square washers available soon.
Notice the picture below of an early prototype. In that prototype I could not screw the body all the way in and I ended up using two washers.
