Direct Link: HERE I apologize, I'm not a videographer. I do what I can to try to help the hobby. I have 50~ cannons being chinese sweatshop assembled in my garage for a dozen or so boats that are being built by me for me, by me for newbies, or by newbies being taught by me, so I figured I had the on-hand supplies to make a quick video. DO THIS AT YOUR OWN RISK. I have no liability if you somehow hurt yourself. Wear eye protection when playing with boat cannons. Wear eye protection when using power tools. Etc etc. Stuff used in this video is linked here: Gun Barrel Material: https://www.mcmaster.com/89785K824/ Gun Barrel Breech Sleeve Material: https://www.mcmaster.com/89895K728/ Gun Pistons: https://www.mcmaster.com/51055K78/ Gun Breech O-Rings DASH 008: https://www.mcmaster.com/9452K16/ 5/16 4 Flute Center Cutting End Mill: HERE 1/4 Compression Elbow: HERE 1/4 Compression Tee: HERE 1/4 Compression Union: HERE 1/4 Compression Caps: HERE 1/8 barb -> 10/32 male thread -> 1/8 barb Tee: https://www.clippard.com/part/TT0-404-PKG 1/8 barb -> 10/32 male thread elbow: https://www.clippard.com/part/CT0-4-PKG Pipe Soldering Flux: https://www.homedepot.com/p/Oatey-H...er-Soluble-Solder-Flux-Paste-301302/100177185 Things not listed above, ask and I can find out or explain.
