I used a variety of wooden pieces purchased from Michael's. I used a 3'' wood screw up through the platform and into the wood. Then I used mending brackets and corner brackets to hold everything together at the joints, then I covered the brackets with more wood pieces. Then I painted and weathered it and installed the cannon using the swivel mount for a lamp (similar to a desk lamp). Then I installed the blue LED inside. Minus the LED, the mounting, construction, and painting took a few hours, total. One thing that must be kept in mind when mounting the cannon is its proximity to your body's midline, i.e., if you mount it directly in line with the platform, it's usually too close to your head, meaning you bump it when you put on your helmet. That's why I made mine come out a few inches... to give it more clearance. This might not be an issue if you use a desk lamp. Hope this helps.
