5lb
mid cutter design (12lb if I use a 3lb lighter blade with more
bite/geared for higher speed) , that should be water jeted in time for
Motorama next year, along with NRL nationals.

They are a good bit large, but allow for you to put more magnets on the bottom, and I assume for this weight class are near indestructible

I've already said this to you, but I feel I should stress... You should make it Asymmetrical.

Will do that, I intend to when I finally get the frame cut, at first get the frame cut, everything but the weapon assembled. Then after that weigh the robot, and design the weapon to use rest of weight.

The ball apparatus under the blade... What is that? Could it be replaced with UHMW? It would allot for the same purpose, with possibly less weight, and with its coefficient of friction between 0.18, and 0.25, It would certainly do the job if its properly mounted.

The ball is actually the weapon shaft , just rounded (will use a metal radius lathe tool).
