Rion,

In a discussion such as this, most likely everyone has a point that is correct; this does not validate rude comments or the "I told you so!" attitude, especially when directed to some of the most respected (for good reason) mentors in FIRST.

My post was certainly immature, but I have a hard time letting things like that slide.



Yes, radii such as those are good, we do them on our wheels; they can be machined easily with a ball end mill. They certainly help make the part stronger and reduce failure at that joint. However, you can see in the picture's Jon linked that they had a radius, and thin spokes can still fail.

Raul was making a valid point, analyze what kinds of forces are on your wheels before you lighten the heck out of them. No one can say "1/4" thick spokes are strong enough" without knowing the floor surface, wheel tread, drive type, etc.
