Most of the tech here was simply copied from existing patterns. The gun build is based on the 36P22 synthesis available on the wiki. I found some rakes with a large enough period and simply copied them. One glider turning reaction was taken from a different rake. I found the other one myself, but it's based on the same reaction (only using a different sparker) and probably already known.
There's definitely room for improvement here. In particular, the bounding box is larger than it really needs to be. I'm sure gains could be made by moving various rakes closer together. I made my puffers such that I could reuse them for both the edges and middle of the guns, so some of them are wider than they need to be. Additionally, they where build with generous vertical clearance, so even the ones building the middle could be tightened up. Finally, the ones at the front don't need to clear the whole gun, so they could be smaller.
Also, to fit them behind each other, I simply advanced to the next multiple of 120 that would allow them to fit without conflicting. This could be improved by using the minimum space required.
More ambitious improvements could be made with improved puffers and rakes. Smaller rakes (if available) could reduce the size of the pattern quite a bit. One obvious improvement would be to use the forward rake based block puffer to build more of the blocks. (I built it later, to avoid a collision, and didn't replace the others.) Changing the construction order could probably give improvements as well. It's quite possible to build various bits of the gun simultaneously (or nearly so), and so "get going" faster. It may also be possible to place the rakes closer together with a different build order. Finally, it may be possible to replace some of the rake based puffers with traditional puffers. (Which might shrink it quite a bit, although, there's not a lot of room to work in, other than at the front.)
Finally, it should be possible to shrink the period by a small amount. I used 120 simply because I found (relatively) small forward and backward rakes of that period. However, the gains would be modest, because the guns cannot get much closer together than they are now. (At least not in this orientation.)
Ironically, the hard part of this wasn't actually building it. Rather, I spent a lot of time trying to build a decent glider synthesis of the gun. While the existing 36P22 synthesis should have made that easy, as a newbie, I kept running into timing issues and got frustrated. After messing about with it for a while, it finally dawned on me that not only did I not need it, but that it wouldn't really help. (The tight glider salvos that it would've required would have been a pain). Once I realized that I should just build the guns piecemeal, it became a lot easier.
I would like to thank Jason Summers for his 36P22 synthesis, which provided the inspiration for this project and was instrumental in it's completion. I would also like to thank him for his extensive pattern collection, which provided the p120 rakes and the glider turning reaction that allowed me to create the salvos needed to start the 36P22s.
I especially would like to thank David Eppstein for discovering the p22 gun, which is the heart of this project and (for some reason) my favorite glider gun.
P.S. I still intend to make a proper p22 gun synthesis, now that I got this working.
