Getting the boom extension finished up. I saw this sheet metal tip on a YouTube channel I think it was mrpete222. He was cutting sheet metal with a hammer and chisel. I saw it and thought it looked pretty crude and completely nuts. But, I got bored and had to try it! I can't believe how GOOD it actually works, so I made a quick video with some pictures and video of the last section of boom extension.
