Okay, so this is sort of off-topic, but I figured someone here might
have a suggestion. I just bought a lightly used GE 3/4 HP motor off
eBay to power my JSP MaltMill. Unfortunately, I didn't realize that the
motor didn't come with a mounting bracket. At this point, I'm at a bit
of a loss as to how I can securely attach the motor to the board that I
want it to sit on. :)
Any suggestions on alternate mounting strategies or places where I can
find the appropriate motor mounting bracket would be greatly
appreciated!
Thanks!

Many motors have several threaded holes in the output end.

Post a link to a picture of the motor faceplate and the rear of the
motor and I might have some suggestions.

We use small motors all the time for testing and are always rigging up
quick test units. You have a few options:
First, if you mean it has no mounting feet, I have used steel/stainless
banding, bolted one end down, wrapped all the way under-over then under
again (imagine loop-the loop), then bolted down the tail end. Do this
on a 1'x1' or so piece of 1/2" to 3/4" ply, and wrap both ends. If
there are vent holes be sure not to cover them. Then put the motor
under load, and make sure it doesn't get too hot. If that works great,
if not you can put a spacer, aluminum preferably, between the motor and
wood to act as a heat sink. If there are mounting holes, just bolt the
motor to said peice of wood.
Once mounted you can use a pulley set to give you the right operating
speed for say a mill. Then mount hinges on one side of the the board
so it hangs down. Then you can either use a bungee arrangement, or
some good sized springs to act as a tensioner.
Hope this was helpful, and not too convoluted.

Sean,
I will try to explain w/o pictures.
So you have your motor mounted on a 1'x1' piece of ply. Mount 2 hinges
on either side of the board tht is parallel to the side of the motor.
Then you can take the board and hinges and mount them on a board or
countertop that your mill sits on. Mount the board so the hinges fold
flat on themselves, and the motor looks like it is just sitting on the
table on a board.
It should be set now so if you lift the board with the motor on it, it
lifts up toward the mill, and should be oriented so the pulleys mounted
on their respective shafts are inline with each other. When lifting
the hinged motor board, the distance between the center of the mill and
motor shaft should decrease.
Now, find a belt that is sized so the hinged motor board sits at a
60-75 degree angle to the table top when the belt is installed. So
lastly you will drill a hole in the motor mounting board near the edge
that is opposite the hinges. Insert the hook of a bungee cord in the
hole and stretch the bungee cord down to a cross member, or another
point on the table you are using, to put good tension on the bungee
cord. This will give you a tensioner for the drive belt that allows
for movement/wobble, and can be adjusted by lossening or tightening the
bungee cord.
I hope that is a little more clear.
Mitch

If you are worried about the curve of the motor body making the
assembly unstable if you just drill 4 holes through the plywood to bolt
it on, they make mounting spacers, little aluminum cylinders that you
can get to make the mounting more stable.
These guys are pretty expensive, but were quick to find. I bet you can
find some at a local hardware/elecric supply store

I will take a couple snapshots when I get home this evening and post
them later tonight.
Thanks.

Thanks. That makes perfect sense. I hadn't thought of steel banding, so
that's a good idea. And easy enough to try out. :)

The motor body does have four holes that appear to be for mounting a
steel motor mount. But, since the body of motor is curved, I'm not
certain it will work to try to run bolts through those holes into the
plywood. I guess I can just try it out.
When I get home this evening, I will try to post a few pictures in
response to Mike Dixon's request. That may make things easier to
understand. :)

Now this part really interested me. I have the pulleys and v-belt all
purchased, but I'm little confused about your idea with the hinges and
the bungee or springs. Could you explain a little more?
Thanks.

Heh. What can I say, I got a good deal on it... *laugh*
It's not a gear motor, but I am planning on using pulleys and a v-belt
to reduce the RPMs. Is that what you mean? Or were you referring to the
amount of torque?

Yes, reducing the speed. You might consider setting it up with a
semi-loose belt so it can slip if it hits a rock, because that motor
isn't going to stop.

Two blocks of wood attached to the plywood so that the curvature of the
motor snuggles between them, not quite toughing the plywood, will form
a good base. Then use a strap or wire around the motor to hold it in place.
3/4 HP is a lot of motor. My table saw works fine with 3/4 HP. Is it
a gearmotor, or do you have a plan to gear it down?
