Yes, 3 phase motors are easily reversible.

On the platen, I don't have a large enough piece of steel angle on hand.

If you're going to glass it right away, I do have a piece of aluminum angle that would work.

Your call, let me know.
What do you mean I can't do that?

Grinder is all finished, less the platen for the double roller rig. Decisions need to be made before that can be done.

Here it is, set up with the interchangeable small roller arm and vertically adjustable work table installed.

8" contact wheel with the work table centered.

Image

8" wheel with the work table underslung for hollow grinding.

Double roller platen arm installed (Platen to be built after decisions made)

Disassembled for shipping, showing the various components.

Frame
Work table arm
Work table extension
Work table
Platen arm
8" wheel arm
Small wheel arm
Tension/Tracking arm

Having a separate arm for each attachment means you loosen one set-bolt, pull out the old arm/tool, insert the new arm/tool and you're ready for the next operation.

Once the motor is fixed in place, there are two adjustments for belt tension. Loop the belt around the wheels, pull the tool arm out to approximate length and tighten the set-bolt and jam nut, then pull the tension arm up for final tension and tighten the set-bolt and jam nut on it. Once final motor position is determined, you may want to find a spring of the appropriate length and strength and pop it in the frame under the tension arm so you have a constant spring tension on the belt. I haven't found it necessary on mine, but I can see where it would be handy.

Okey-dokey. I'll get that done tomorrow morning and it should get dropped off at the UPS place tomorrow.

I spent part of the evening planning the packaging, I think it'll be pretty secure.

I'll email you with the financial details after I ship it.
