So any project presents the dilemma, buy or make... Well I look at making as kinda the fun part and really labor costs are the worst in any project and relative to the rest of the world, my labor is cheap.
So now there is a real prototype wheel for the as yet unnamed robot. Several hours slaving over a benchtop lathe and voila. The specifics so far are as such. Extruded billet started around 9 ounces. The mid point was down to 7.5 and the final form, speed holes and all, was a scant 2.71 ounces. Could always be lighter but this is pretty good. With the Traxxas tire the unit weight is 3.96 ounces which will make the full set right at a pound.
The next model might have something better but this will work for now. Keep it light keep it simple right?
