Leong i was thinking about that. I might try making another version that is a tighter fit to the sides. I actually filed down the sides a bit to allow for clearance of the screws that are used to hold the idler to the hull. the downside is that right off the bat i can't see a way to make the piece any bigger without running into fit issues. I might also try to reverse the position and have the L on the bottom instead of top. Just an idea at the moment though. part of the problem with the idlers is that where they attach to the front glacis is only slotted and not a complete circle. This can cause the bow out problem Tanker 10. I'm sure it was done for a good reason but it makes for the front to easily bow out.
I'm still working on it and I haven't given it a proper run since Danville. Hopefully I'll figure something out. Of course RustyTrax has been running his just fine without any kind of brace in the front and with metal tracks as well.
