Looking for a buggy project

[BrianG]

Unfortunately, ~13mm is a bit too tall. The batteries have to be mounted at an angle so they fit lengthwise, but then that brings them close to the edge of the body where there isn't much room height-wise. So, I have to keep the tray as close to (but not touch) the dirt guards so save as much height for the batteries as possible.

That's a good idea though - I'll have to keep that in mind if I see something that is small enough to work. I was planning on drilling some ~10mm holes in the bar to help cut down on the weight, but you have the right idea. How would I secure the bar to the chassis and batt tray - locknuts? As you can see in my crude drawing, I'm using the thickess for the "meat" for the threads.

If only the actual chassis was wider with smaller dirt guards! I know it's for weight considerations, but still aggravating!
