I have several Shimano 3 speed "F" Hubs that need to be disassembled cleaned and lubed. I purchased the Shimano Ball cup tool. Both Glenn's and Sutherland's make it sound like you just screw off the right hand ball cup. I have the hub clamped in a block of hardwood with a hose clamp to stop it from rotating. It still slips in the block. These are hubs with out the rim so I do not have the rim to pull on, but the force I am using seem way more than any spoke would with stand.
How do I get the ball cup to unscrew? Any recommendations will be appreciated.

Drop in a few spokes and hold the hubshell in a vise by clamping those spokes tightly. Use a wood block to keep the flange from getting marked on the top of the vise jaw. You should be able to get it free. There are small notches on the outside of that cup. Once it's positioned and you have some wrench pressure on that cup tool, have an assistant knock the cup counterclockwise with a punch.
It's trivially quick when the hub is in a wheel. -- Andrew Muzi <www.yellowjersey.org/> Open every day since 1 April, 1971 ** Posted from http://www.teranews.com **

I have a hub so badly stuct that with 4 screws instead of spokes into a 1/4" plate of steel I still cannot get it loose. So I do not think it is triviall.

You're right. As I noted, in a wheel it's no trouble at all.
Use a punch and hammer, strike a purposeful, firm blow. It will move. You want impact more then torque. In a poor setup (anything not in a built wheel), the ball race tool won't break a rusty race from the rusty hubshell. A nice massive 11-inch punch driven by a 14 or 16 oz hammer will. -- Andrew Muzi <www.yellowjersey.org/> Open every day since 1 April, 1971 ** Posted from http://www.teranews.com **
