Assembling some wheels eh? We need six, my cordless drill is working overtime drilling every hole ready for tapping thread. It's all M4 so just my trusty 3.2mm drill and me.

This is an inner hub, the big center hole fits a ball bearing. 

Some wheels; we're printing them on low quality, this saves time. Doesn't have to be pretty!

Inside each wheel is one of these:

Servo, bracket (it just snaps on), axle with bearing and whisbone. Notice how the wire feeds through the bearing.

Wheels, assemble!

So this took quite some time and patience. I cheated a bit and also assembled the steering servos to two of the wishbones, can you spot them?
