Hey, dcb (hey those are my initials, too), that's the exact same motor/switch that I bought surplus some time ago for converting a push mower, so it should be the same power range as what you are looking for. The only difference is mine came with a yoke to attach a blade.
Be sure to weld in a cross brace behind the motor and attach supports for that third mounting hole to it. It won't hold long just attached to the handle like that. Otherwise, it's looking good! |

did you weigh it before and now after?
Looking at the pics it looks like you lightened it up a bit. |

Minor progress, found a belt at grainger, a 3l390 , hopefully it is strong enough.
still need to weld pully together and beef up motor mounting. Actually ran it for a tiny bit though (till the pulley unbolted itself) Will need some alignment tweaks too: |

They say the snow is coming so I dusted off the welder and sorted out the pully/motor arrangements.
The pulley was two pieces so I welded it at the seam, sort of, from the inside. First welding in many years. Then I held the pulley on the motor with a bolt and adjusted the runout and knocked it straight within a few tries and deposited much welding wire Tricky welding, gotta focus on the shaft since it is so thick. It should be mostly braces and alignment from here. |

Ok, it is together enough for me to want to try it
This is your basic piece of threaded rod and a few angle brackets and a piece of metal strapping approach. It sounds faster than the original at top speed, starts up like an amusement ride. I'm a little nervous around it , so will probably add a shield or just cobble the covers back on, but gotta try it. |

Looks all ready to go. I hope it holds together. I wonder if it'll work better with the higher speed?

Alllrightee
Had a couple inches this morning, first test was quite manageable. I blew one circuit breaker and had to move to another circuit. But it is a lot quieter and smoother. It also has noticeably less torque , so maybe a smaller motor pulley would be in order, you have to use a fair bit of finesse to keep the rpms up, but I can live with it. |

Followup,
The snow got a lot wetter towards the end. I was really overtaxing the motor, was packing snowballs on it to get it to quit smoking so much while trying to finish up. This rig is overheating with 2 inches of wet snow. The blade speed is about right so it probably needs more motor. I managed to finish but had to let the motor rest a few times. plow stick would have been about as effective. Ah well, a $30 experiment Now I know, get more motor. |
