One of my cannons on my Bismarck is not firing properly. When I do fire the cannon sometime in it is not allowing the maximum amount of air through so I dont get much power. Also, when it recoils to load another BB it is very slow. I know that the cannon is the problem. Any ideas?
More down angle where the "T" is fed from the magazine might solve the slow reload problem. You can also place a magnet on the far side of the "T" to hold the next bb in place. Check your hoses for crimps for the weak firing.
In addition, check the cannon's fittings to make sure they are tight and sealed. Any air lost out of a loose fitting or even the interruptor end cap will lower the air pressure and cause weak or hang fires.
also, if homemade, check the inlet tubes, they can get plugged or partly plugged with solder durring assembly
