I can't get my cog off.
I'm trying to fix my spoke and I can't get my cog off for some odd reason. I greased it up when I put it on, so I don't know why it won't come off. I've tried some tools that I have like a chainwhip, some screws that I used as leverage to get it off, and some other basic leverage tools... but it wont come off.
Any ideas what is going on?

If you have access to a vise use a couple blocks of wood and put the cog in the vise.

I actually have not but I read an email from Sheldon explaining how to do it.
Edit. I went back to orig email and remembered he used old chain. Look below.
"My usual technique for seriously recalcitrant sprockets is to wrap a
length of old chain around 'em, then clamp the two loose ends
together in a bench vise." Sheldon

Oh alright. That makes sense. I'm basically putting a lot of pressure and leverage on it right?
Sounds pretty reasonable. I'll see if it works tomorrow.

Just remember, when using the vice method to remove a stuck cog, which direction you need to turn the wheel ('steer the bus'). Its easy to get it wrong.

use rotafix method.
when facing the bike on the chainring side, you will be turning the wheel clockwise to un-screw the cog.
make sure that you have removed the lockring first.

Be careful using reverse rotafix. You can actually bend your chain stays and screw up your allignment. I am assuming you have a steel frame.

Sounds like a personal problem.
When I can't get my cog off, I usually just try to relax... maybe use a little extra lube...

How much of a danger will the reverse rotafix method be to my bottom bracket shell?

I'll go down to my LBS and have him help me so that I feel better about doing it.

use the vice.. but wrap the cog in motorcycle chain instead of the wood blocks.. you can clamp hard on the chain.. oh .. and when steering the bus.. turn left!
