So I was just trying piddle with a geek breach cannon build and for the life of me I can't seem to figure out how to get the tubing restriction ring around the tubing. So what is my sleep deprived, child addled brain missing?
If you cut the ring very narrow, and warm it up, it helps. Using a lubricant (saliva works) also helps. Cursing like a sailor is also good.
Take geek breech. Throw geek breech in trash. Replace with Foster breech. ... Profit! Been there, done that, won't be doing that again.
