HP Lovecraft,
That about sums it up with what needs to be done. I saw a double trouble once 12 years ago when I was a an airsmith at a field and I have a good memory, plus I did a 10 page detailed sketch (minus accurate measurements) of how it works, the parts, and how to assemble one in one of my airsmith notebooks. My hypothesis that one of the double troubles can be duplicated is from these sketches. I would need a double trouble in my hands to be sure and get duplicates made.
I did talk to Chris, and I understand how a double trouble modification is not that great, but I would like a chance to try and improve the trigger pull if possible.
Moreover, if a double trouble is not ideal, I am playing around with a better idea of a pneumatic reactive trigger system for a VM-68, but for it to work really well, the setup would need a tippmann cyclone feed system. I know, I know! I need to finish the dissertation instead of thinking about this stuff. ...But I know this would work!
Litessa,
You're getting married? My heart is broken. The only decent lady (who happens to be the only female on the planet who loves the vm-68) is not taken.
My soulmate is gone.
But alas, Congrats on getting married
.
As for the double trouble, I understand your concern about losing the double trouble. Would it be easier if you could get some test duplicates made on your end? I'm willing to help with the $ costs.

Like you said, everything is pretty much the same, though with the Double-Trouble, they also made the trigger pull itself much longer. The reason was the return spring was made EXTREMELY heavy. Basically, heavy enough to release the primary sear on spring-power alone.
That means when you pull the trigger, you have to push against that sear, doubling the force required to pull the trigger. To minimize that, they increase the trigger pull, increasing leverage, and decreasing the effort required.
The obvious question is, if you are going to modify the stock trigger, is there room in there to add a 3rd sear, plus linkage, and a much beefier return spring?
Looking at the stock trigger, there seems to definetly be room, if you trim the primary sear a bit to make room for the 3rd sear. Perhaps right next to the 2nd sear. There is already a notch. You could just enlarge it enough to hold the 3rd sear. Connect the 3rd sear to the opposite pivot point so that it goes up, while the 2nd is going down, etc.
