SPI Wheel coupling cracking like crazy!

Coach on team #481, NASA Ames / De Anza High School, from De Anza High School and It could be you!.



We are using the wheel couplings from Small Parts. We have been following our robot around (No, it is not done, thanks for asking) for about two weeks, picking up nuts from the coupling as they fall off. Yesterday we put lock-tite on them, tightened them hand-tight with a cheap little screwdriver. Today the couplings are completely falling apart. The plastic is cracking and pieces are falling off. Anybody else had this experience? Is there some kind of reaction with the lock-tite, or are the couplings just really cheap?

Very Frustrated,

Eric
Team 481
