Mark V electrical cord replacement

[woodmeister]

I have to replace the electrical cord on my Mark V. Don't see where shop smith carries them. Where is a good place to look for one adequate for the job? I see there are two wires from motor going to switch and two wires from the cord going to the switch. One (ground I suspect) has been cut off from cord to switch region. This is a 3 prong plug how and where is it grounded? Any suggestions?
Thanks,
Tom

Buy a 14 ga or heavier 3 wire extension cord and cut off the female end. Ground wire goes to metal case of motor.

If you are replacing the wire using something other than the SS replacement go to 12 gauge wire. On my machine 12 gauge made a day night difference in startup and run power. I can start my SS at full speed with no problem. And I can cut at full depth of cut with a full kerf blade into 4x6 hard pine with not problem, blade buried in wood and the machine happily cranking on.

I got s 12 gauge extension cord 50 ft cut it at about 20 feet used 20 ft end with the plug end as a new power cord or my SS. Put a new plug on the rest making a very handy 30 ft extension.

Believe 12 gauge does make a difference!

Also the extension cost me less than $30 at one of the big box stores.

What's the easiest way to replace the cord, do you have to remove the lower part of the headstock and isn't the motor attached to it???? Can't see working though the access hole on the side.
Thanks

on the wire insulation there should be some letters as well as the w:ire size ,,, those describe the properties of the insulation,,ie: oil resistant,, direct burial ,uv resistance ,, etc ,etc,,, you dont have to use the same type but it,,,, IMO ,,,,would be advised.

Yes, dropping the motor pan will be necessary. If you remove the belt cover and raise the left end of the way tubes about a foot (adding a support piece of wood at that left end), I typically remove the screws holding the motor pan, and then fish the belt off of the motor. Add more wood / cardboard to protect bench tubes when you lower the motor pan with motor still in it.

You'll need to get access to the end of the motor on the operator's right side to remove and re-attach ground wire. Other two wires connect to the switch, and I've found it easier to remove the switch for connecting wires to it ... my hands aren't all that large, but still they barely fit thru the access hole, and then you're working by feel alone unless you remove the switch.

If you use non-Shopsmith cord for replacement (which I think includes rubber stopper-type strain relief), then you'll need some other type of combination grommet/strain relief.

Attached are pictures of a couple of types of strain reliefs, and a few shots of my relocated power cord ... never liked it coming out of the bottom as it interferred with my sliding storage shelf.

You will need to 'drop' the motor/pan to access the original cord/strain relief. As for connections, the power cord will only attach to the switch(and the ground wire elsewhere) or black wire to the switch, and the white wire attached to a motor wire(with slip on connectors).

A good way to 'drop' the motor pan/motor is to raise to vertical, pull the table out of the carriage, put the table back in the carriage, but from 'below'. This will provide a shelf for the motor pan/motor to 'drop' onto and support them while working on it.

As for the cord itself, an extension cord works well.(#14 or #12) Cut the receptacle off and strip/crimp terminals. You may need to replace the strain relief(covered above).

Thanks for the reply and help. My ground pin pulled out of the power cord which is my reason to replace it. I got it back end, BUT...... need to fix it.

Just replace the plug!
