Forge Blower - 550 motor

This is a forge blower i made to work with a 550 sized motor that i scavenged from an old power drill.

The motor had a 9 tooth gear on the end of it so i decided to use that as the coupler to the fan.

The housing is designed to take different tube end adapters the one currently in the files is for a 2 inch Sch10 or sch40 pipe. I may make other adapters later.

I found a PWM 420w motor driver on Amazon (will find link later) and and using that to control the fan speed.
