Also the cross-members can be replaced by a good belly-pan. Just make sure you support you transmissions and this looks like a great WCD.
Just a few questions...How are you going to tension the chains? and why did you choose the Toughbox Mini's?

Chain Tensioners: I will have to add that to my list of To Do`s

Toughbox mini`s: Inexpensive and gave the gear ratio i needed for a fast robot with 4in wheels.

By slotting the front and rear bearing block cutouts your can use the axle as a chain tensioner.

have you considered sliding bearing blocks for tensioning? Of all the systems ive seen that seems to be one of the most elegant and simple.
I just have to say that it looks awesome....team 772 has always been a team to look up to! Hope to see you guys at GTR and...i have too....
7 - 7 who? 772!!!
Its so catchy!! after u guys chant it in the stands its stuck in my head for months!

LOL! This was the best post I have ever read :')

Thanks for this, it made my night (Canada juniors are ruining it).

I will most likely use a sliding bearing block now. I usually would put a slot for a tensioner in the middle of the chain (for sheet metal chassis) but seems like more people are doing a sliding bearing block for WCD.

A mid-chain tensioner would add weight and inefficiency to the system as a whole. The reason for switching to WCD (mainly) is to remove weight and increase efficiency. Also since you have individual bearing blocks already, its simpler to just pocket out the aluminum box extrusion and allow them to slide.

that russian team! beating us on our own turf ruining all our nights!
