	The SimpleBot has two ~~wheels~~, and each ~~wheel~~ is made up of a sandwich of two pieces of ~~CorFlute~~. ~~The wheels are held on via fine wire, we~~'re using "wire wrap" wire designed for electronics.		The SimpleBot has two wheel assemblies, and each assembly is made up of a sandwich of two pieces of Corflute, a cross-shaped servo horn, and short pieces of wire. We're using "wire wrap" wire designed for electronics.

	[[File:SimpleBot wheel ~~pieces~~.jpg\|400px]]		[[File:SimpleBot-wheel-1-parts.jpg\|400px]]

	~~Cut~~ two ~~medium length~~ pieces ~~of wire~~, ~~and run~~ each ~~through opposite holes~~.		Place two of the Corflute wheel pieces together, aligned so that the ribs on the wheels are at right angles to each other for maximum strength. Sit the servo horn on top, with the thick mounting lug facing up:

	[[File:SimpleBot wheel ~~with wire pieces~~.jpg\|400px]]		[[File:SimpleBot-wheel-2-horn.jpg\|400px]]

	~~Each wheel is made up of two identical~~ pieces of ~~CorFlute.~~		Cut 4 short pieces of wire (about 7 or 8cm each is plenty), bend them in half, and insert them through the servo horn and the holes in the Corflute:

	~~On top of each~~ wheel~~, run the wires through the "servo horns" that mount on the servos:~~		[[File:SimpleBot-wheel-3-horn.jpg\|400px]]

	~~[[File:SimpleBot servo~~ horn wires~~.jpg\|400px]]~~		The central mounting hole on the horn should line up with the hole in the centre of the wheel, with the wires poking through:

	~~The central mounting hole on the horn should line up with the hole in the centre of the~~ wheel:		[[File:SimpleBot-wheel-4-ties.jpg\|400px]]

	~~[[File~~:~~SimpleBot servo horn wires from back.jpg\|400px]]~~		Once everything is lined up, twist the wire ends together tightly to hold the horn in place:

	~~Once everything is lined up, tie the wire ends down and cut them off.~~		[[SimpleBot-wheel-5-ties.jpg\|400px]]

	[[~~File:~~SimpleBot ~~servo horn wires cut off~~.jpg\|400px]]

	'''NOT SHOWN: For the "cross" type servo horn, repeat the process on the other two corners to make a stronger binding between the horn and the wheel. On the "straight" type horn that is shown, you probably also want to run some wire across the horn through the opposte corners, to bind it as tightly as possible to the wheel.'''
