Seeing them axle gussets reminds me of something when I was 16.
Im not sure if your familiar with race 4wheelers, but I got a new handlebar from TAG. Its the kind without the crossbar in the middle and the big square headpad covering the mounts.
The rep from TAG says to me "If you bend these, I assure you you wont be riding for awhile"... Well needless to say, I didnt ride for 6mo and still really dont anymore after I bent them.... and they were bent less than a 1/2in down on one side..........
Them axles give me the same impression. Really enjoy the build, and love the new buggy. Hope it comes together soon.
