Fot those who might be making lower drive shaft seals (for Early Kiekhaefer K Models)
Use 3/8" center and 7/8" outer punches
The 1/2" drive shaft and 3/4" bore are tight fit for seal so
saturate seal with leather oil and it will install easier.
Pressure of spring forms the seal into cup shape.
The key is the washer that locates the large punch so the outer diameter concentric
to the center hole..
The brass washer just happened to be right size and on hand.
I doubt this simple idea is original.
