Alright, it works.
It didn't work because I installed the solenoid on the air compressor backwards. Whoops.
Let me first say this is not by any means a do it yourselfer. Don't even attempt if you've never dealt with gears before.
Easily the hardest thing I've ever done.
Start with who worked on the project: Me, My Dad, and my neighbor (mechanic).
Phone calls I made today installing the air locker:
3 calls to Marlin Crawler
1 call to Yukon Gear
1 call to yotamasters in Corona, CA <--- super nice guys! I would recommend them to anyone!
And you'll probably ban me for saying this next thing but,
my camera broke.
It works now though, and that's all that matters. Tomorrow I will take pictures of the air line routing and such.
I have school tomorrow too...
