Hi All! 
I have been looking at how scale torpedoes are fired on Frank Ricucci website under “Operating Instructions for Torpedo System.doc†at http://www.modelbrass.com/torpedoes/torpedoes.htm. I am a bit lost as to how the system is constructed since it lists using 2 tubes. “1. Outer tube is brass tubing with ID two sizes larger than torpedo diameter. 2. Inner tube is brass tubing with ID one size larger than torpedo diameter.†One tube and the breach at the end make sense. Why would a second tube be necessary? That is, isn’t just the outer tube required for holding the torpedo? Thanks, Ed
