Construction and Assembly Plan

 

            We will be constructing and assembling this water balloon launcher at Chessie Marine Sales and at Dale Watson’s home in Elkton, MD.  Dale works for Chessie Marine Sales and will be getting us good deals on our supplies.  Since all of us live in a dorm room at UD, Dale has offered us to let us use the store and his home for the construction and assembly of the water balloon launcher.  That way we will have access to tools and other needed assembly conveniences.

KTPPA Revisions

 

 

            The design changes done to the crossbow as a result of the KTTPA are.  We decided to sand the surfaces of the launch ramp area to reduce the possibility of splinters busting the balloons on launch. We also decided to do more research on the trigger to make sure It will work Properly and is toughly lubricated to reduce the possibility of sticking. Since there are several variables that cannot be determined until testing is completed like the strength of the bungee and the functioning of the trigger we decided to revaluate during and after testing.
