I have a 12 v Dc golf buggy motor.
I have fitted the motor to my milling machine as a table feed .
I am going to fit a rotary switch to the motor , being a 3 position switch to change the polarity from forward and reverse
Ie + And - to off then - to + changing direction . I will also install a variable pot give feed control.
Is there any thing I should any thing I should be a wear of that I am doing wrong. What size pot should I use
You wouldn't normally control a motor as powerful as a golf buggy one by simply putting a variable resistance in series with it, if that was your intention. PWM would be the normal method.
What is the current rating of the motor?
There are many PWM based controllers on ebay cheap, if needed
You will need a beefy 12v supply however.
Most use a ex T.M. motor as there are plenty of mains fed drives available for these.
Max.
Make yourself a little chip guard if you think they might get into the motor.
+ be aware that the motor may not be continuously rated, so might not like making a 20 minute cut, but thats going to be unlikely.
Did you connect the motor with a flexible coupling?
This is the motor and information .
There is no flex coupling as I have made it direct drive from the reduction boxI have supplied a photo of the power supply v 240 ac to 12v Dc The motor maybe 180 w
If spanners etc stick to the motor its permanent magnet.
Coupling looks acceptable.
You need some kind of pwm speed controller, maybe this:

Whatever you go for massivly overate it, stuff these days is under rated.
