Reliable Motor

[waznyf]

Hey everyone,

I have been looking around for sanding/buffing motors and to be honest, I'm struggling to find one that doesn't seem to be "cheap".
Could anyone direct me to well made motors? Can't seem to find any on my local Craigslist either.

I greatly appreciate it guys!

Regards,
Frank

Don't be afraid of "old" motors. If you buy a decent new one, save yourself some pain and buy from grizzly.com. I would not get anything less than a 3/4 hp. One of that size can be had for $110 from grizzly.
Sometimes you can find old power tools to harvest motors from, but you can pretty easily end up with a lemon.

A 3/4 HP baldor that reaches 1750 rpm should be just fine I would hope?

That would be more than enough. My beat up old motor is 1/3 hp, and it does great. I have to throw a lot of weight on it to slow it down, and if you're using a coarse grit (36-ish) you won't need to do that.

I'm looking at a baldor buffing motor on Craigslist right now. It seems to be in great condition but I'm worried about the shaft size and speed.
The shaft is 3/4 and I know that the arbors sold by Tim West are 1/2 and 5/8.
I'm concerned about the speed as well. The motor is single speed and the guy says it reaches 3600 rpm. Seems like a lot! I remember reading in a previous thread that a speed of that sort will damage the briar.
Am I just over concerned?

Regards,
Frank

You can use 3000rpm if you want but it takes practice and confidence to use it well. Personally I use 3000rpm with a 40grit disc for shaping, most will find this too fast however and the recommended 1400-1700 is perfectly fine.

I'm like Chris, I do roughshaping with 36grit at 3000rpm, then move to 60 grit etc at 1700rpm. You're going to loose a bit of skin and/or nail, though!

Now what about shaft size? The motor I'm looking at does not have a shaft size that corresponds with an arbor from Time West or the Pipe Makers Emporium as far as I know.

Tim West makes arbors in any size you need Just mail him! I got myself a 19mm one from him last year

You might not even need one, my 2 motors I bought earlier this year are 24mm shafts, but as all motors they also have a threaded hole in the shaft, which is the exact size of the screw I put through my sanding disk. So I just screw my sanding pad straight onto my motor's shaft, works great!
You might be able to pull off the same trick with a jacobs chuck and mount it with a screw (some jacobs chuck are ment to be mounted that way).

Great to hear

Guess I'm all set than!
