Poor man's spline

The engineers here at Alamo CNC needed an inexpensive and detachable way to connect a steering shaft to our custom steering rack (seen previously). So, in lieu of buying a $75 manufactured spline assembly, we came up with an $8 homemade alternative! The hard part about making a custom spline is the female connection; a special tool called a broach is needed to cut away the inside of a shaft. In our case, we just bought a standard 12 point socket for $6 

Enjoy!
