Hi Mark,
I have a tip for you. It's a bit easier, but it would take some time. One of my Hispanic friends helped me with the tool clamp. I promise that if you use Wilton and Park, one of the two outcomes will happen that are stated below. I have seen one frame bend. 1) I take a spindle and slip it through the face of the cup. 2) Put the D side cup tool on the cup, sharp edge down. 3) Pile a bunch of flat washers on top to hold the cup remover down firmly with torque. (Remember not to torque too much or the cup can't back out) 4) Place the cup remover tool into the Wilton vise and tighten on the cup removing tools edges, flat side facing up with vise jaws contacting most short edges. 5) Tighten until the tool cries. 6) Walk the frame around with one or two people.
Shazam!!! The workbench is a pipe work bench that weighs 450 lbs. that is built from 1/4" plate and 3 inch schedule 80 pipe that I built when working in the oilfield.
Either the cup breaks loose or the frame curls under. Promise!
Best Regards, John Proch La Grange, Texas

John, I presume you mean the drive side cup? I have yet to fail in any cup removal attempt when using one simple tool ... a 5-6 foot long piece of schedule 40 PVC tubing as a monster cheater bar. It's lighter than steel and easier to heft into place, yet it gives great control with light effort, especially if you can get a helper to hold the tool firmly on the cup flats, while the other person inserts it over the tool and gently applies careful, even pressure. Just be sure to get a tubing large enough for the other end of the tool to fit into, and it's POP! ... loose cup ... every time!

Hey Vintage Bike Enthusiasts,
Please let me know how you removed the stubborn S side bottom bracket cup because I have a stubborn cup on a 48 Bartali (on topic) on the D side that was painted over because the previous owner could not remove it. Anybody have any idea what might have been stock for the Cambio Corsa frameset?
Thanks everybody,
