From what i have seen it is a fairly simple task to join two belts together to form a 50-dart belt with a blank in the center joining them, but what of belts longer than this? Written instructions are rather vague on the specifics of joining a belt onto this 50-er, spouting things like "repeat this process for longer belts" , despite having no blank to work with on it.
B = Blank
D = Dart Holder
Normal Belt of 25 > BDDDDDDDDDDDDDDDDDDDDDDDDD
Modded Belt of 50 > DDDDDDDDDDDDDDDDDDDDDDDDDBDDDDDDDDDDDDDDDDDDDDDDDDD
This method also presents the problem of the first dart not being fired, as the vulcan feeds the belt in before firing (if fired properly. I'm sure somebody will wrestle the belt into the popped out AR to prove me wrong).
Ideal Belt of 75+ > BDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD...
So put simply, is there a way to join non-blank ends of belts together? Or are belts of more than 50 darts a myth?
