Can anyone help?

I have a 1/4 hp ac motor that I am looking to make into a drum sander

ex. http://www.pixelpuddle.com/sanders/

so the motor that I have has eight wires. The diagram is as shows

Purple ------------------ ung'd line
|
|
brown -------\ |
\ |
red ---------+-------- |
/ |---------low voltage line (110 side)
orange -------/ | 110/220
|
|
yellow -------\ |
\ |
black ---------+--------------
/
white-------/

green with stripe ------ ground

It says on the label this is for cw direction and if switch the black
and the red wire I get ccw direction. (or vice versa I forget which)

I bought a Double Pole Double Throw three position toggle switch
(on-off-on) but I just cannot figure out the proper wiring. I want it
so that I have cw on one side of the toggle - center being off and ccw
on the other side of the toggle. Can this be done? - If so - cna
someone tell me how to wire it. If not - is it the switch or is it that
I cannot do what I want with this motor. I guess I can always just use
one direction but it would be nice if I can reverse it.

Crossover Switch:

former Black ----+---------o on 1A
| \
| off o o------- New Black
| 1C
Former Red --- | ---+----o on 1B
| |
| |
| ----o on 2A
| \
| off o o------- New Red
| 2C
---------o on 2B

Cheers!

Hi Rich,

Thanks for the info. I still do not get it though

There are six posts on the switch

3 wires on the cord (i know green goes to ground)

That leaves 7 wires to be attached to the switch. Where do I put those.

I realize that I probably have to keep

brown and orange together

yellow and white together

do I use the purple ungrounded wire at all?

If I were to look at the posts

1----2 on cw
| |
| |
3 4 off
| |
| |
5----6 on ccw

what gets attached where.

Thanks again -

Jeff

If the diagram that you gave in your first post is accurate, and the
motor runs (in one direction) then leave them the way they are. According
to your original post, only the black and red needed to be swapped to
reverse the motor.
If I were to look at the posts

1----2 on cw
| |
| |
3 4 off
| |
| |
5----6 on ccw
I've replaced my designators with your numbers:

I've done the switch diagram in the way a standard schematic
is done. For each switch, there are three positions:

On Off On
o 1,2 o 1,2 o 1,2
\
o o 3,4 o---o 3,4 o o 3,4
/
o 5,6 o 5,6 o 5,6

Interpose this between wherever the red and black are coming
from, and the point where they attach. Connect the black wire
to 1 and 6, and connect 3 to the terminal block on the motor.
Connect the red wire to 2 and 5, and connect 4 to the terminal
block on the motor.

But this is all assuming that the rest of the wires don't
need to be changed _at all_ - if that's not the case, then

Good Luck!
Rich
