TYRONEEZEKIEL Posted July 6, 2010 Posted July 6, 2010 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"
Ventsi Posted July 6, 2010 Posted July 6, 2010 (edited) 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... Edited July 6, 2010 by Ventsi
