2020-04-11 (F) Weekly Summary

I was comfortable enough with the knife design to start building my portion of the tools for the annual gathering. A few days ago, I ordered the necessary parts, like more stun guns and rubber training knives. Just getting the materials ready for assembly was a day's worth of work.

I thought about the design for the switch adapter, which was glued to the pipe, and trapped the nut. This design was not serviceable, so I took a day to add bolt holes so we could swap out switches if the pipe or adapter broke in a fight.

The printer ran continuously to make three adapters and spares. When it came time to assemble the knives, the procedure ran smoothly. The most challenging part was adding standoffs to the rubber knife blades since I made their sockets snug.

Finally, I had three working combat tools, but I had to show the rest of the group how to make them. I couldn't expect them to read through my whole procedure and pick out the necessary steps, so I revived the Hackaday.io page I started months ago. Of course, anyone who wants to see how we're working is welcome to view.

I tried to write a safety warning that would be fun to read, and still convey the importance of safety. It didn't have the conviction, and it wasn't necessary, so I toned it down. Then, I kept working on step-by-step instructions, starting with the bill of materials, and the plastic switch-pipe adapter.
