Have this stuck lockring on a formula hub. thing is on there really tight. spanner just kinda seems to eat away at the lockring since i have to put so much force onto it. (yes, i am turning it clockwise. jeez.)
Any good tips before i go at with my freakin teeth?

take a few shots before you go at it with your teeth. it will hurt less

get a better tool (hozan pliers et al)

spray some penetrating oil on it.

A good shop will get it off in less than five minutes, but not if you've stripped the notches by then.

took the words out of my mouth before i even opened the thread.

PB Blaster is what I always used to use on Jeeps when I used to wheel, it would get the biggest, knarliest most rusted to all heck bolts loose.

What tool are you using?

It probably won't help the notch stripping problem, but I almost always have to take a mallet to the other end of the spanner to get lockrings off.

Don't use vice-grips or locking pliers. If it doesn't work, it will tear it up and you will be in worse shape than you were before. Lockring pliers are the tool to do it.

You can make some ghetto lockring pliers by getting a cheap set of channel-lock pliers and filing the jaws down so that they have a prong on the end of each jaw.

A pipe wrench might actually work. Don't try and grab the notches though, it's designed to grab the smooth round sections.

Use a cold chisel and a hammer. That worked for me after the lockring spanner tore the notches apart, rendering the lockring spanner totally useless.

BTW, since the lockring was buggered anyway I didn't care if it was damaged in the process. If it's an aluminium lockring the cold chisel may damage it. But then again, lockrings are a lot cheaper than hubs.

hellz yes.

Yup. This is the best stuff on earth. PB Blaster or Liquid Wrench. After you spray it on, let it sit for about an hour, and spray it on again. Wait a few hours, and then give it a shot. MAKE SURE YOU LET IT WORK FIRST!

Probably what happened is that you tightened the cog against the lockring. Usually if you turn the cog the opposite direction with your chainwhip, you'll take enough force off the threads on the lockring to remove it. Caveat: you could possibly strip your hub doing this.

The same mechanical principle applies with the cones in your loose-ball hub, but you're not torquing on the cone, usually.

Has anyone used a Hook Spanner Wrench to remove your cog? Not the bike specific ones, but one's made by Snap-On, Mac tools, etc? Just asking to see if that would work as well.
