How to remove a stuck BB?
 
I am replacing the cranks and BB on my Windsor Hour, and noticed that the drive side of my BB is stuck to the frame. I already removed the non drive side, but cant seem to budge the drive side. I read somewhere that they sometimes loctite it to the frame, is this true? I am turning it clockwise to loosen, correct? Its just the stock BB that came on my bike..

What kind of bottom bracket?

There are generally two problems.

The first is getting your BB remover to stay in contact with the bottom bracket. If it's a cartridge bottom bracket you can usually find a bolt to hold your BB remover in place. Also, a genuine Shimano BB tool, which sets closer to the centerline of the bike frame, works much better than the Park equivlent.

The second is getting enough torque on the BB. I've had good luck chucking my BB remover vertically in a sturdy vice and using a helper to thread the bike onto it. Take a minute to determine which way you need to go and use the whole bike frame as a lever. This has never failed me and I've never damaged a frame.

+1...this is correct. Just make sure you know exactly which BB you have and which way to turn the bike!

This worked perfectly. Was able to generate enough force by clamping it in a vice. Thng was a ***** to get off though. Thanks for the info

If that fails, a little penetrating oil and let sit for 24 hours.

If the penetrating oil fails...just light it on fire.
