Heat Pump Custom screws

Two screws holding the fan speed control module to the fan motor on a heat pump rusted through and broke off causing the fan to wobble and knock.  One of the original screws was used as a model to make new ones.  The stock was turned down to the major diameter for an 8-32 screw.  The lathe was stopped and with the stock still in the chuck, a hand held die for an 8-32 thread was used to cut the threads.
