Below is a portfolio of recent and past work
Bearcat 1101 Feed Mixer/Grinder - salvage repair/rebuild of pin clutch on tractor PTO input shaft. The original part fractured through the keyway and threaded fastener hole. Upon failure the key sheared and damage was compounded, fracturing the rest of the casting superstructure
Salvage repair was performed by removing the damaged superstructure, milling flat; crack testing the remaining material. A repair sleeve was made and brazed in from above and below.


Custom twist drill solution - adapting a stub drill bit to act as a pilot for a counterbore. The stub bit started out with a 1/4" hex shank, and was ground down precisely to 3/16" for the pilot bore of the counterbore, with a flat for the retaining set screw.
This allows the customer to perform concentric operations in one setup, while preserving benefits of batch production
