KMG clone question - why not put the motor under the tool arm? (wrong forum?)

Turns out I have enough scrap in my box to build one of these fine creatures.

I do not likewise have much bench space to put it on!

Every KMG I've ever seen has the motor to the left of the grinder.

Why not flip it 180 degrees to put the main body of the motor under the tool arm?

This would decrease the width required by almost half.

Assuming a TEFC motor, I can't see any reason that would be a problem. The belt path might have to change a bit, but again, not a big deal.

Am I missing something here?

Some have done it & I agree it can be usefull.

Rob set it up on the left & clone makers just copy that
 
Seriously? Someone must have done it the way I'm thinking of.

I'm also looking for examples where people welded it together, or used square pipe etc.

The original design seems unnecessarily complicated with everything bolted together etc.

I suppose that the bolts were easier for a full CNC solution?

I wonder if he tapped the holes on CNC too? I bet that you can do that if you have the right tooling and programming.

Another solution for lack of bench space is to mount the motor under the bench, with the belt coming up through a slot.

I once visited an elderly woodworker who had one large motor at the end of his long work table. There was a line shaft running on pillow blocks under the bench. Each tool was connected to the shaft by a belt. He popped the belts on and off the pulleys to hook up whichever machine he wanted to.
 
Well, I know the motors that I use would not fit to the right, nor under anything, unless I made a special table so that I could have the motor vertically under the grinder. To the left just makes it easier IMO. Yes, it takes a little more room, but you dont need a special table just to hold your grinder.

If you search NWG you can see a version made with tubing & Tracy Mickley sells plans for that.
it is called No Weld Grinder - so it uses tabs to bolt together, but welding is neater and better.

No reason not to. You will of course have to make the support legs longer and be careful of which way the motor turns.
 
Erik, I always love seeing pics of your grinder. Great creativity and execution!! Never gets old.
 
Thanks, Jon.

I love it. Tracy did an amazing job with the design and there is so much room for modification. I don't think I would trade mine, but I would like a VFD set up some day for this, the disc, and a horizontal.
 
OP: Because the motor and cord would get in the way of changing the belt? Although, Erik's setup does seem to work with a belt drive setup. Direct drive wouldn't work that way.
