Re: pic: FRC294 Prototype base almost done
How heavy is it? How about each component?
It seems such a shame to hide such nice wheels behind a big ol' plate, but the design seems sound. I think that if you're diligent about checking your chain tension, since it appears the tensioning idlers aren't spring-loaded, you won't have to worry too much about the chain wrap on the center sprocket. If the chain gets slack, though, the excess is going to gather up at the bottom and come off that sprocket.
Almost purely for aesthetic reasons, I'd try to lower the idlers along the top and bring the chain down inside the panels.
Why are you starting with 3/8" plate and pulling so much material out of it instead of say, using 1/4" -- so they're still thick enough for bearings -- and saving yourself some machining time?
