I like the design!
Same question, why 5 shafts? If you lose chain you could be unable to drive any of the wheels, whereas if you direct drive a wheel you are guaranteed at least one wheel under power.
Second, Are you using the w pattern traction wheels?

Third, Why go with exactly 112" perimeter? This may sound dumb, but why go as close as you can, because a tape measure may be short or you could bend your frame making it bigger... (my team usually goes at 111" to be on the safe side)
Fourth, I have not worked with sheet metal before, but is it strong enough to support the wheel bearings without versa blocks or something to that extent? i have seen it done with thicker metal, but not sheet metal.
As goes with all of my advice on CD, try it yourself and make up your own mind. I'm just suggesting things based on experience. See what works for your team. Follow my suggestions to the letter, mix and match them, or even throw them completely out the window. It's all about you and your team. - DampRobot [more]
