How do you make a Power Cord Spring?

I posted this in another group and was asked to move it here... The
saw is a Sears Craftsman Computerized Radial Arm Saw model: 118198610

I am replacing the power cord on a Radial Arm Saw and unfortuately, the

manufacturer does not just supply the cord but you have to buy the cord

with the motor. The power cord is coiled (like a spring) so as the saw

moves across the arm, the cord is stretched and as it moves back, the
cord contracts into a tight spring and stays out of the way. I plan on

getting an extension cord to replace the bad one, but the question is:
How do you make a straight cord to contain a permanent coil?

Any help is greatly appreciated.

You can order one from Whitney Blake.

That was the first one I found after googling for coiled power cord.

Thank you everyone for helping out with your comments. I ended up
going to the site Gerald mentioned above. They were pleasant on the
phone to deal with and will ship out today. The only thing is that I
will have to splice the wire because I wasn't going to pay for a
special run of a single cord ($100 setup fee).

Again, thanks for all the help.

1 out of 4 Americans are mentally unstable. Look at your three closest
friends and if they seem normal then it is you.

You don't. That cord was manufactured that way. You can try to coil it
around a pipe to shape the coils and they will exhibit some small amount of
recoil, but it won't be like you are used to. You can afix (tape) a spring
to the cord near where it secures to the motor and back somewhere near where
the motor normally sits and that should work.

I don't know how they make it, but I've seen this type of cord used in
various industrial and commercial applications; Electrically operated
overhead doors with safety bumper shut off switches on the bottom edge
come to mind. Without checking, I'd be willing to bet it's available
from the usual suspects, Grainger, MSC, etc.

You don't.

Try a search for "koil cord".

The cord is a commercial item.

I know you already found one, but just for the sake of speculation, I
wonder if a guy could pull braided wire through a coiled air hose to
get a similar effect. It's almost certainly not up to a standard
electrical code, but it might do in a pinch...

I must be sane then. I don't have 3 close friends.

You buy one. These things are available (in the UK anyway) as coiled
kettle leads.

Or else you take a normal piece of extra-flexible powertool flex, coil
it loosely by hand, and run it over a tensioned wire or length of
elastic to hold it in place.
