This was an incredibly difficult project to fixture. The goal was to shorten the king pin bosses while maintaining perpendicularly to the pin centerline. By holding the king pin a 3-jaw lathe chuck clamped to the table the pin was perpendicular to the mill table. The king pin boss fit tightly and was clamped down with a bridge clamp on a bolt tightened in the set screw hole. The axle was supported with a screw jack and captured to prevent rotation. Once held properly, all that was required was simple CNC program to circumscribe the king pin. It worked fabulously!

This project entails engraving a logo onto the knock offs prior to chrome plating to put the finishing touch on an awesome custom hot rod.
The plan is to ball mill the vintage Ford V8 logo on the center. To ensure an accurate engraving the convex surface needs to be modeled correctly.
The easiest way to hold them with out damage is by the threads.
To prevent damage, hold concentricity and location we used custom soft jaws on a 3 jaw lathe chuck.
It’s important to clock the rotation prior to machining for appearance consistency.
We made several adjustments until we got the right width and depth for the paint inlay.
The line widths are consistent; looks like we modeled the convex surface spot on!
Another challenging project executed perfectly.
