I am now working on some simple pole weapon prototypes. Spearheads and other pointy ends are mounted in an axial groove, fixed with two screws. It gives an advantage, if we need to be able to change configuration. Other than that, we may need a permanent fixture.
My idea is to use non-protruding rods and to fill gaps with some kind od resin / glue.
It needs to be elastic enough to wthstad vibrations and hits, while rigid enough to transfer force to the shaft.

> I want to make a hole in the bottom/side of the bucket so clothes won't get stuck on the wire. The wire cannot be detached from the spinny machine. So i have to cut a hole (in the bucket) big enough for a USB to fit through, then make the bucket water proof again. **I'm not sure how to make it waterproof again.**
By now, the process of creating custom lithium-ion battery packs is well-known enough to be within the reach of most makers. But it’s not a path without hazard, and mistakes with battery protection and management can be costly. Happily for those who are apprehensive on the battery front there’s a solution courtesy of a group of engineering students from the University of Pittsburgh. [Their project was to convert a pedal bicycle to electric assisted power](https://hackaday.io/project/180098-diy-ebike-battery-system), and in doing so they didn’t make their own pack but instead used off-the-shelf 40V Ryobi power tool packs.
The bike conversion is relatively conventional with the crank replaced by a crank and motor assembly, and a pair of the Ryobi packs in 3D-printed holders on the frame. The value in this is in its reminder that these packs have evolved to the point at which they make a viable alternative to a much more expensive bike-specific pack, and that their inclusion of all the balancing and protection circuitry make them also a much safer option than building your own pack. The benefits of this are immense as they bring a good-quality conversion within reach of many more bicycle owners, with all parts being only a simple online order away. Take a look at the video below the break for more details.
Those Ryobi cells [certainly seem to have carved themselves a niche](https://hackaday.com/2020/02/20/diy-power-station-puts-ryobi-batteries-to-work/) in our community!
