Time fuse selection

How does one select time fuse for the correct length and diameter for a specific diameter of shell.

 

For instance, what length of time fuse X of diameter Y goes into a shell diameter of 3"

Tyrone, are you asking if one uses different diameter time fuse for differnt shells? If so then no, 1/4" dia. is the standart, there ARE some other types that are bigger or smaller but 1/4" is the standart. As far as how long of a piece of TF to use, it all depends on how fast it burns. For example a 3" shell wants 3 seconds of delay, Skylighter has some tables for this, but in the end its up to trial and error.

 

Edit; Sorry, I seem to be hogging the forum, though there aren't much folks around and I'm boring my a$$ off at work...glare.gif

Is this what you were looking for?
