Metal Sanders

So After my Millermatic 211 Purchase, the next thing I bought was a 1HP 10" grinder. I'm thinking I would like to get a belt/disk sander combo as well, or at least make one or the other.
I have a pretty good source for surplus electric motors locally for pretty cheap, and its got me thinking about making some tools. Has anyone made something like that before?

I also picked up a 1/2 HP 1750 RPM motor last week for $20 and i'm trying to figure out what to make with one that small.
I was thinking about using that one for a disk sander, but not sure if it has enough power.

Check out this idea, you could probably make something like this up in a day or two.... http://www.mickleyknives.com/html/no_weld_grinder.html

Iíve been thinking of a bench mount drum sander for cleaning up the inside radius of gussets, tubing, etc. Basically a small flat table with a drum sticking up through the center.

I think it would be a good compliment to a disc sander, which I seem to need every time I use my POS cold saw.
What do you think about the Auto-Set feature on your 211? I was skeptical at first with my 180, but now itís all I seem to use.

I love the autoset, but sometimes I'll bypass it and crank the wire feed up a notch. I don't need to really, but I just like the feel of it better with a bit more wire speed than it gives me.

Building your own belt sander has been discussed on here a few times. Just do a search for 'belt sander'

Here are a couple that I found....

I have the dxf file that Zancat sent me for the one shown in this thread. If you would like me to send you a copy let me know.

I have a kalamazoo 2"x48" belt sander in my shop. It's probably the most used tool in my shop. It uses a 1/2 hp 3450rpm motor. I would be happy if it were just a bit slower. At 1750rpm it would just as usefull.

Here is the one I have. http://www.use-enco.com/CGI/INSRIT?P...PARTPG=INLMK32

They also sell a version so you can power it yourself. http://www.penntoolco.com/catalog/pr...ategoryID=4992

Then there is the build your own version shown in Captianfab's links.

I know people aren't always fond of the Harbor Freight stuff, but they are selling their combo belt and disc sander for $75 right now. I've been thinking about it, and just get metal sanding belts and a disc for it. They use a 4" x 36" belt and 6" disc.

I used to have the harbor freight 6"x48" belt / 9" disc version of that combination sander. The disc was unusable, it had (no lie) 1/8" of runout. The belt portion was decent, but way underpowered.

thanks for the links and info guys... I kind of had a handle on the belt sander part, but the disk part was what has me stumped without using some sort of dual shaft motor. I know that when I worked at CBI offroad, I used the disk part more than the belt part.

I guess I could do it with a jackshaft or something. I want to get my hands on a couple styles and see just how they are put together to help get the creative juices going better.

run your motor to a jack shaft thats got the lower belt roller on it and sticks out enough to run a disc on the end.

A belt grinder for metalwork is usually about 5000 fpm on the belt. You calculate this the same way you would the blade speed for a band saw.

I hear a dedicated metal belt grinder can remove material (and skin) at an amazing rate. That's one of my next projects.

You might want to check into Coote belt grinders. He offers a 2"x48" and a 2"x72" model, with an optional 9" disc. He just provides the grinder, you are responsible for the motor and the stand. I have a 3450 RPM 3/4 HP motor I got at an auction that I'm saving for a grinder.

Thats what i use,the company i worked for at the time was going to throw it in the dumpster because the drum was cracked.I called delta and got a new one and have been using it for more than ten years.The nice thing about the 6" belt is you can grind stuff flat.

I would search CL until a old delta poped up.i just saw a beauty here in Jersey for $300,6 by 48 with disc!

I love the bling of JMR's, and we all know that Baileigh is nothing but top notch as well.
Me, I finally got working again, but i'm still playing catch-up on finances and will be doing that for a while to come yet. So, the more stuff I can make myself and save some money, the happier I am.
Plus, the satisfaction of making something myself is half of the fun of it.

try bidspotter.com too

I've snatched up a few deals on there, alot of large manufacturing plants closing

I agree, the JMR is super bling... just needs some candy powder coat over that shiney aluminum (shamless plug)
