I started by cutting off the original cannon, which had already been modified into a Vanquisher by the previous owner. Onto this I attached a short collar made of 7/16th inch tube styrene from Evergreen Scale Models. I can slip alternate cannons into/onto this collar changing the Leman Russ for whatever threat awaits it.

To make the Demolisher Cannon I used three different diameter tubes. The outermost is 1/2" in diameter and 7/16" long. Inside that is a 7/16" diameter tube cut just a couple of millimeters shorter than the outer tube. Inside that is another tube 3/8" in diameter and 7/16" long. Once glued together (one inside the other) you get a short little barrel that has a 7/16" groove which the slip collar slides right into.

To make the Battle Cannon I used a length of 3/8" tube with a small length of 7/16" tube for the muzzle brake. The vents in the muzzle brake were cut out using a razor saw, hobby knife, and my miter box.
