I won't be able to open it up like you see in the photo. The layer that goes above it will cover less in the center of the bike, so I need to leave enough room to make sure it isn't exposed.Will you be able to remove the panel that covers the chain?
I'm also curious as to your use of ABS for guides, those are some harsh angles to subject the ABS to. I doubt if the guides on the bikes that use these are subjected to such angles.
I see plenty of room for a couple of jockey wheels in the front, if you change a couple of angles on the chain you would only need two in the front.

The channel will actually be fully open though. Guides for the top chain will be along the wood and guides for the bottom chain being between both chains, but not down the entire length of the bike. I ended up going with HDPE plastic, its low friction and has high abrasion resistance. I'll have photos of this solution soon.
