Holding a motor in vertical position

[ashwinearl]

Any ideas for straightforward approach to holding a motor in a vertical position for disc sander? I seem to be overthinking this.
I've seen the plates or frames from past posts, searches. I'm not interested or capable of any serious fabrication.

I'm wondering if some thick MDF would work for a plate that overhangs the bench.

I would think with some bracing that would work fine.

What type of mount does the motor have? For a face mount, the thickness of the MDF might not leave enough of the shaft protruding to fasten the disc. I would suggest 1/4" piece of steel plate to make something like in your last picture. It only requires drilling a few holes and a bit of grinding if you want to round the front. The holes do not have to be terribly accurate if you're not using flat head screws.

Use a 56C face motor.

I use the Beaumont style plate like your last photo. It is 1/2" aluminum. You have to mount it solidly on the edge of the bench or on a base.

If I built one again, I would make it portable, I would make it from a 12X12" plate of 3/8" aluminum or 1/4" steel and put the mounting hole in the center. You could mount the plate on a box of 2X12"lumber, aluminum side plates, or the legs setup in your first photo. You could also permanently install it in the workbench top by cutting out a hole for the motor to hang through. A 12X12" frame of 2X4 lumber would raise it up a bit to make use easy.

I love the looks of those setups in the top pic.


Here is mine I recently made, and posted earlier in another disk grinder thread......









I'm kinda surprised how Fun these are to use.

It is 56c , from a polar bear forge grinder . I thought about tilting the polar bear frame on its side, but the 9" disc would hit the frame.

When I downsized my woodworking I made this to use as a router table that could be put anywhere.

Someone a while back posted a photo of a disc sander on a stand with a hinge on it, for vertical or horizontal position. I just bought a disc sander not to long ago and put it on its own stand, I may just incorporate a hinge into the mounting plate like that.

I lucked into a bunch of heavy T-slot bar in several sizes a while back. Using these versatile bars to temporarily or permanently mount machines is really great. It is quick to mount and unmount things by sliding them in the slots and twisting of a couple lock screws.
You will soon start to see all sorts of uses for holding jigs and such. Catch pans and spark funnels stay in place and can be slid from grinder to grinder.
The possibilities are endless - removable worktables, hand sanding stations, sharpening stations, mounting work lights, small accessory/parts holders or pans for bits and small tools, etc. Many of these can be made to just slide in and out.

Just an FYI, but on Craig's setup I would have skipped the thick top plate/back plate assembly and just mounted a simple plate on the feet. Four holes drilled in the plate would match to the T-slot bar. If using a 3"X3" double T-slot bar you could mount the disc sander horizontal or vertical.

What's ironic/funny is that I have a side mount on my motor...... I didn't Need to make anything...haha. I'm holding it with my left hand in the one pic.

*But I machined my bolt hole pattern and large bored plate before I salvaged the motor and drive.

I think AMK's disc sander frame has a hinge to go from horizontal to vertical.

If motor frame/housing have mounting legs fix motor on side of work bench , can t be simple then that ?And if you make two plate , one on motor one plate on bench you can make it to rotate horizontal/vertical with just one bolt .

This is a face mount only motor, it doesn't have any legs.

I'm going to try face mounting it to and 1/2" MDF benchtop and see how that goes.

MDF doesn't hold screws well. I'd try and through bolt. It also tends to warp easily under constant pressure. Not to mention what happens when you get water on it.
My grinding table has a piece of 3/4" MDF on it and has warped significantly just from dunking blades while grinding.
When I set my new shop up I'm pulling the MDF and replacing with plywood.
