Topic tags/keywords: question

I’m hoping to get some great ideas to put an electric motor I have to good use. It’s a 1/3 HP, 3 speed, 1050 rpm motor. I know it’s not a lot of power but there have got to be some uses I’m not thinking of… And lets rule out an air filter right off the bat, I have another motor with a squirrel cage fan already to be used for that purpose. Looking forward to seeing some the ideas from the great minds here.

What are the mounting options? I have an old motor with an accessory arbor on it on which I have stacked three wire brushes. Great for de-rusting and cleaning bolt threads and that sort of li’l stuff.

Kindly,

Lee

A psa disc based grinding/sharpening unit, that’s exactly what I’m holding out for a 1/3-1/2 HP motor for and yours sounds ideal as it is lower rpm and I assume the “3 speed” gives you two other speeds below 1050rpm? If you can get access to it there was a good shopnotes article on a unit that sat on a drill press table and used an axle from the chuck to spin the discs, but you can do a standalone unit with a motor, pulleys and v-belts.
Check out the lapsharp sharpener foir thge general idea.

Other than that, a benchtop disc sander for light duty sanding tasks, or a conveyer belt to serve up sushi to workshop visitors?

A disc sander would be my suggestion. I’ve seen some nice ones here on Lumberjocks.

I thought about a sander but wasn’t sure that it would have enough power to do any real sanding( ie a drum sander). I like the idea of the grinder but other than occasionally touching up chisels I don’t know that it would get much use. It has about a 3” shaft so I could mount a pulley to that and it has 3 brackets attached to it’s face for mounting the motor itself. I think making margaritas in the shop would get me in too much trouble and I’m not a fan of sushi but thanks for the ideas so far. If I were to mount a larger diameter pulley to the motor and a small one to a sanding drum connected by a belt, it would spin the drum faster than the 1050rpm, but would 1/3 hp have enough “torque” to make it work as a drum sander? If anyone has any experience with this.

At the slow speed the motor runs at, it might make a good power
center for a buffing/grinding mandrel. Before affordable home shop
grinders came out, guys used to hook up a washing machine motor
under or behind a buffing mandrel. Mount a friable (white) wheel
on one side and a linen buff on the other and you have a slow-speed
grinder for your edge tools and you can put a razor polish on your
chisels and plane irons with the buff charged with jeweler’s rouge.

Yet another vote for grinder, buffer, wire wheel. all together at one work station. Maybe removable top so said work station has multiple functions.

Let us know what you decide

Well I dont think a potters wheel would get much use and while I like the idea of a sharpening station, I don’t want to take up the limited space I have for something that will get minimal use. This project will be put on hold while I put a new motor in the truck, but thanks for the input everyone.
