I have a few electric motors in commercial dryers with warn keyways on
the shaft end that holds the fan any suggestions on how to repair.
Keyways are 1/8 in. Thanks Martin

Use a roll pin in place of a square key. *Prepare new keyway by
mounting the fan without the key, and drill down the keyways with a
smaller drill -- say a number 13 (.185") for a 3/16 (.1875) roll pin.
Use a BFH to seat your new key.

How would I get the drill bit that close to the shaft to drill
parallel to the shaft
