wizard7611 Posted July 19, 2015 Posted July 19, 2015 (edited) I've been seeing quite a few large cylinder shells lately, but was wondering what you use to absorb the shock from the lift charge. Another question I have is how would you absorb the shock from the lift charge on a triple or quadruple break ball shell? Edited July 19, 2015 by wizard7611
Arthur Posted July 19, 2015 Posted July 19, 2015 The shell has to be strong and firm enough to take the shock from the lift, while still functioning correctly. However sometimes there are two board discs with a roll of newspaper between them, located between the lift and the shell. on being hit by the lift force the paper absorbs some shock and passes the lift force evenly to the shell bottom, it also spreads outwards making a better than usual gas seal between the shell and the tube, so more lift comes from less (or less good) powder -used especially on Maltese shells where the shell (Salami) sticks out of the top of the mortar (there might be 2ft in the tube but another two feet above (yes Maltese Salamis are very long certainly as tall as a person.))
nater Posted July 19, 2015 Posted July 19, 2015 I usually use an extra disc or two on the bottom of the bottom break.
