I saw this done on one of the youtube channels
I follow. Does anyone have experience using an attachment like this? What would I need to do to attach the disc to the drive wheel

I'm sure there are good reasons to do this attachment method,
but here's another take on this

In this youtube example, the user has an existing VFD.
For $100 you can buy a 3 phase motor and wire your VFD to run a separate disc grinder with a dedicated motor
And you can place it wherever you want

Of course that's what I did and that's why I'm a proponent of it :-)
I'm a fan of dedicated equipment

I guess my initial reason is the cost of another motor. Ive been searching craigslist for months for a three phase motor with a 56 frame. Nothing within about 120 miles. Especially for $100. Eventually i could take the disc off and put it on another motor. I still have to buy a vfd as well so i was hoping this could work for a while.

I just don't know what I need to do this...a longer shaft for the drive wheel?
 
Somewhere in Cincinnati there's a shop that redoes electric motors (or 5) that has pallets of 3ph motors just waiting for a home. I'd be surprised if you couldn't pick one up for fifty bucks or maybe much less.
As far as the particular frame, all you need is the right shaft to fit your disk, the motor has mounting bolts- you can bolt it to a piece of plate (or plywood, for that matter) and get right down to business.
 
I personally would not do that to my kmg. I'm also with elementfe here, I don't use a 56 frame motor to power my grinder. In the case of a disc grinder you do have to make sure the frame you get has the correct shaft size as mentioned. There are many motor guides out there that will tell you which frame has the correct shaft size for the disc you want.

I'll probably go this route at some point. I'm not that good with electrical stuff so I'll probably just need to sit down and dig online for some easy to follow instructions about how to wire the VFD for two motors.

Some good threads were brought up here, just last week.


I had this in my photobucket

You can do like Salem showed and just keep daisy chaining them on and on
 
I have an Esteem, a GIB and a 9" disc on the same KBAC VFD.
I added a switch to the VFD to divert power to a female plug. The disc and Esteem run off the plug. Since I don't own my house/shop, the plugs allow all three machines to be separated and moved wo re-wiring.

Sorry for the sideways photo. It is straight on my computer but it turns when I post it.

This is what I did. I use it just like another tooling bar. I didn't go with a stand alone disc grinder to conserve bench space.
Works well in both vertical and horizontal positions. Having the ability to raise and lower the grinder gives me the option of standing or sitting while working
I placed an arbor adaptor on the shaft opposite the disc and use it for handle finishing tools like a sanding mop or ball.
Here's a better shot of how it's put together

The attachments won't open, can you try them again?
Thanks for the reply
 
Jonathans: You did good..... I just might have to use that idea myself. That allows an easy variable speed disk for VERY low cost.

The pedestal is from a dilapidated barber's chair. It operates with a hydraulic foot pedal.
