Countershaft Wear - So How Bad Is This ?

Taper pins usually are made by drilling the hole (undersize) with two different sized drill bits. Drill the shaft thru and thru with the smaller diameter bit. Then turn shaftmover and drill the top half of the hole with the larger bit. Then run your tapered reamer down the hole to create a smooth taper for the pin. Hole always must be smaller than largest diameter of the pin. That way the pin wedges nice and tight in the Hole. When it gets worn, ream a little more- fresh diameter, and wedge the pin again at the larger diameter. Neat stuff!
