Vintage pedal service?
I have the pedal apart but was wondering if there is a special tool to
Turn the cup to tighten? I don't think a socket will fit but I was able
to loosen it with just a screwdriver it wqasn't on very tight. The pedal
had a nout with a slotted washer and then the cup

Are you thinking all pedals are designed like the others and that each is serviced exactly the same way?
How 'bout a pic or a model number?

I just rebuilt a pair of vintage SR pedals for the first time a couple of weeks ago. I found it easiest to just hold the side of the cone with a slotted screwdriver and adjust tightness by turning the spindle until you're ready to lock it down with the retaining nut.

Thinking on a Leotard pedal Park made an old tool like the CCW-2 but smaller. I use a thin walled 7/16th socket from an old ChiCom DXed socket set...

My go tools are a flat bladed screw driver jammed along the side of the cone and a socket or wrench on the lock nut. I have a few model specific pedal bearing tools (including the Shimano one mentioned) and they work well, for their specific pedals. Andy

I've done this a handful of times because many other hobbyists would rather toss them than rebuild.
My approach is just like other adjustable bearings. I'll find a socket that works for the cone, and screw the core down finger tight, then back off enough to leave a small amount of play. Next, slide the slotted washer onto the keyway and start tightening the lock nut. If the pedal spins freely and there's no play with the lock nut tightened, the job is done. If the bearing is too tight or still has play, adjust the cone looser or tighter, and repeat.
The key to this (a pun!) is the keyed washer. Without one, you'll want the flat screwdriver to try to keep the cone from tightening along with the lock nut.

I wanted to add that pedals use an absurd amount of balls in the bearings. You'll usually need 44 1/8" balls to rebuild a set (11 per bearing, 2 bearings per pedal). IIRC, the set of Lyotard Berthet pedals I rebuilt used 5/32" instead.
Notes will help. Try to track how many balls came out when you open each side, because it might not be the same. Measure the balls to be sure you have the right size to replace what you take out (some shimano pedals use the smaller 3/32" balls).

I find that if, after tightening the lock nut, the bearing is too tight, backing out the cone with the larger of the two sockets will generally give the correct play. The anti-rotation washer only helps so much to prevent the lock nut from changing the cone's position.

No, there's a lock nut that holds it in place. Just use a socket wrench on it. In your other hand, use a pedal wrench on the inside flat to hold the axle still.
Just like your vintage bb's, vintage pedals (that are serviceable) are pretty much serviced all in the same way. Though you may need to use a different socket (typically 10-12mm) on the lock nut between sets.

I use a socket to set bearing preload with my fingers. Then I use a socket on a ratchet to tighten the locknut. I'll echo your tip to use an open end wrench on the flats to keep the spindle from moving. I'm usually using the vise, myself.
