Are you using 25 or 35 chain?
Also, what is the material for the gearbox sideplates?
254 typically uses Delrin, as it is much lighter than aluminum and strong enough for this application
Finally, when looking at your picture, there are grooves cut out in the front of the side tubing.
Am i correct in thinking that you will be putting another black crossbar in the front?

The sprockets are for #25 chain. The reason that they are so large is because I was originally planning on using cross braces that are as tall as the sides and the sprockets would need the chain to clear them. I simply haven't been motivated to change them.
The side plates are currently aluminum but theres no reason they need to stay that way. The grooves in the front to so that the sides are identical and can be switched without needing to have one of each. The actual would probably use another to mount bumpers.
