    Mortar/Cannon Rules

    Please tell me where I can download the O'fiishul NSSA Artillery competition rules. Those which pertain to time and safety on the line and scoring.
    Thanks hanksfx@huughes.net

  3. Part of N-SSA cannon construction rule section 10.2 states, "The liner must be closed at the breech end with a steel plug, sweat-fitted into the liner and welded." The term "sweat-fitted" is not known in the machinist circles I frequent, so could you explain precisely what this means?

    Thank you.

    sweat fitted

    GGaskill,
    I am surprised your machinist(s) do not know what a sweat fitted plug means.

    The liner tube is heated to expand the tube and the plug is inserted. After the tube has cooled, the plug is welded to the tube.

    Take care and be safe

  5. That process is known as shrink fitting amongst the people I know; it was brought up as a guess but no one had ever heard "sweat fitting" before. The only sweat process anyone mentioned using that term was sweat soldering (tinning both parts separately, then assembling and heating above the melting point of the solder.)

    If this is the official definition, it will clear up the thoughts of a number of people I know.

    Thanks.
