RC Car Wheels

You may recall my post about the Ferrari F50 wheel model I made in 2004. Well, it seems the time has come to make the darn thing!

Vertical axis mount of the 3 jaw chuck for concentric work holding.

Magic unfolds!

Sadly, I have been unable to finish the wheel. Without a highspeed lathe style cutting operation on the rim tub, I cannot give it a "turned" finish look. Second, it takes hours for the mill to do what would take a lathe seconds to finish. There's a way, but for now i'm moving on to newer ventures.

More to come!

P.S. I tried making a video of the endless wheel machining footage, but alas it was awfully boring to watch. Maybe next time!

Driveshaft spacer

Adding a lift kit and big tires on your truck can wreak havoc on certain drivetrain components. The one under consideration today is the loss of driveshaft engagement from the axle being in greater droop from it's original position. The easiest solution for me was fabricate a metal spacer that pushed the two co-linear driveshaft pieces back together. 

A small ring of material was left on one side in order to keep the spacer concentric and well balanced, and a similar ring removed from the other side. It fit very nicely.

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!
