Custom identical metal forming mandrels turned for a local performance engine header manufacturer.
This swimming pool filter clamp is no longer available. Instead of spending a small fortune and retrofitting a new filtration system the customer brought me the broken part to make one. With the cost of making the CAD model and the CNC programming was rolled into the first part the customer liked the reduced cost of a second part and elected to have us make him a spare.

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!
