Is the switch being used to turn the motor on and off or is it a speed control? A speed control on an AC motor is something you will need more info on. They and the motor have to be compatible. Are you doing the line cord switching at the foot switch or at the motor J box. Does the switch have a cord to connect to the motor if it inputs the the line cord at that point? Is there a strain relief connector for the line cord? A switch turning something on/off always breaks the black wire using common and NC contact. If you use the NO contact the motor will run when plugged in and the switch will turn it off. Those answers will pin down what we need to know to help you. Pictures tell a big story also.

Same thing, just do the splicing in the J box. Line cord to box, switch cord to the box, cord from motor to the box. Black line to the switch NO, black motor to the switch Comm, splice the white line and green to to motor to motor white and green.

You are saying two different things in your two last posts. Ignore the green and white in the switch unless it is a metal case. then you need to splice in the green in the J box. Remember, line cord black wire is to the Common switch wire or terminal, Switch Normally Open wire or terminal goes to the receptacle black terminal. White and green line wires go straight to the receptacle terminals. If you cannot get it to work that way you need hands on help. Are you sure the switch is not a speed control? If it is that is your problem.
Send pictures, models#s and complete descriptions. Have you search the internet for info on the switch? This is really a simple thing to do with minimal electrical knowledge. This is how electricians make their living.

You need a few items,
OLD CORD< Heavy duty PC power cord would work or old Electrical Appliance cord that has 3 conductors.)
Cord should be White, (on neutral post, larger of the two flat terminals in Molded Plug)
Green should be (Round Ground Post)
Black will be to the (smaller of the two flat plug terminals.)
===
Take a small section of the cord cut it off and wire it into a BOX with a standard 3 prong outlet. Black to HOT, White to Neutral and Green to the box outlet ground.
Take that Foot Switch, and use the BLACK wire from the end of the PC/HD molded 3 wire plug. Wire that to the :Normally Open: terminal on the Foot Switch.
Take the free end of the OTHER cut off drop cord that is in the Plug/Outlet Box. Wire the Black to the :Common: of the Foot Switch.
Take the White and Green wires inside the Foot Switch and wire them together, there MAY BE a Green Ground inside the Foot Switch (case ground) that you need to wire a small section of green wire into the case and tie them all (greens) together.
The there should be 2 whites tied together with a taped over wire nut.
Be sure to test the switch and verify it works prior to buttoning it all up. put a Meter on OHMS and test between the small flat post to the small flat in the outlet, when switch is made the meter should confirm it.
TAPE up the switch contacts inside the foot switch in case water is spilled or coolant on it to slow electrical issues...

From the way you have described the switch, this may help with the understanding of the switch.
The "common" terminal is shared by the other two terminals.
The "Normally Open" (NO) terminal should NOT show a connection to the "common" terminal when the switch is not pressed.
The "Normally Closed" (NC) terminal SHOULD show a connection to the "common" terminal when the switch is not pressed.
When the switch is pressed, the NO terminal should have connection and the NC should NOT have connection.
In other words, the NO terminal is OFF and the NC terminal is ON when the switch is NOT pressed. The NO is ON and the NC is OFF when the switch IS pressed.
The white and the green do NOT go to or through the switch. Only the black is connected to the switch.
The black from the "live" (power) side of the switch should be connected to the "common" terminal.
If you want the drill press to turn ON when you press the switch, connect the black going to the drill press to the NO terminal. If you want the drill press to run and the switch to turn it off when you press the switch, connect to the NC terminal.

The BLACK from the WALL that when plugged in is HOT should NOT go to the COMMON of the switch because anytime the foot switch is OFF there is power to the N.C. side of the switch which could lead to a greater chance of shorting out. That is for this type of application, other applications would.could be different.
Tie the constantly HOT line to the Normally Open (N.O.) side of the switch so that when the foot switch is pressed the power flows thru the switch to the common (C) and into the new outlet box you wire in & plug the drill press into.
The Switch on the drill press would then be left ON so when the foot switch is stepped on the machine runs.
