Nice job. You only need a check valve on it you're planning on integrating into another air and want to use the same point. With the Marvelous Salvo integrated into the SM1500, you'll have problems firing one first then the other. If you fire the Marvelous Salvo first, then all the air in the SM1500 air tank will leak out through the first BS barrel. Depending on how lucky you are with the SMDTG trigger, if you fire the SM1500 first, then it may cause too much back pressure and fire one or more of the BS chambers. Sometimes, though, you get lucky and the SMDTG trigger seems to not allow enough back pressure to cause this problem, but that's very rare. By the way, the SM1500 is the second I used to integrate on a Marvelous Salvo...so to sum it up, if you put it on there and use the same pump, you'll probably need a check valve.
I'm keeping they two systems separate. I don't fancy ANOTHER trip to Home Depot or wait for McMasterCarr. It's not a intergration, as much as slapping a MS on the SM1.5
Nice job, now I have something to do with my 2 BS pumps. The only problem I see is the pump is close to the SMDTG trigger, so your going to have to put the pump near it. Which may make it harder to integrate it to something. Also, I'd suggest using plumbers goop to not only make it hold better but create an air tight seal.
It's not to bad, I extended the trigger a little, making the det' a little longer, but my intergration is going well.
Zap-a-gap already made a air tight seal, I might put goop on it over night just for reinforcement and another layer of protection, but it's working great as-is.
*Edit* Ok here's my abomination. The faint of heart should not look.
Yeah... Here's a close up of how I did the trigger. BTW I'm right handed.
