Re: WCD vs Standard

Also, can you weld the AM Flanged bearings to standard aluminum wall? (6061 I think).
I am pretty sure that those bearings are steel not aluminum, so welding them to aluminum isn't really possible (As far as I know). but anyways, there are far easier ways to mount bearings than welding them, as Mark already said they can be pressed in or super-glued. On our robots we usually hold the bearings in with a screw and washer that covers part of the flange.

The smaller wheels allow for smaller gear ratios and sometimes fewer reductions in the gearbox, this usually results in a more lightweight gearbox. I do not know about keeping the wheels as far out as possible as a motivation for smaller wheels, I would usually try to do that anyways regardless of wheel size (just my preference no real reasoning on my part behind it).
