I never thought of that. Drill a hole in the wrong place and all you
have to do is run the motor backward to fill it back in?
... sorry I couldn't resist
In reference to your motor, a reversable motor has 2 identical
windings wound out of phase about 90 degrees. The L1 goes to the
common point between them and you either hook the capacitor or line 2
to the other ends of the windings (one each) The winding that is L1/L2
is the run winding and the one that runs through the capacitor is the
start. There is usually a switch in there to disconnect the capacitor
when the motor gets up to speed.
There are lots of kinds of motors so you need to know what you have
before you start swapping stuff around.

Use left-handed drill bits.
People should always say why they are asking a question.

oh .. I dont know .. it was a pretty simple question. I am a shop nut
working on my shop more than on projects. There are potentionally lots
of hacks to my equipment that could benifit from this knowledge.
I guess if you dont know the answer, you can always be funny.
or not

Not sure I understand. Are you saying there are a lot of people who
could benefit from knowing how to reverse a motor? I'm sure there
are.
But people should always say why they are asking a question (unless
there is a good reason not to ;-) ), because there may be more than
one path to a solution, like here.

The joke's on you. I wasn't trying to be funny. Apparently you don't
know about left-handed drill bits. I guess if you don't know enough
to understand the answer, you can always be sarcastic.
Instead of asking me or someone if LH drill bits exist.
I'd email you in case you're stopped reading this thread or this ng by
now, but you don't give your email addrss.

Actually LH drill bits wouldn't work. My mistake.
But I think the rest of my last post was still on target, since I
think your reply was based on your idea that they don't exist.
