    seized bottom brackets.

    bottom bracket is iiiiin there good. I've already made a device to hold the tool on the cup. I've sprayed some liquid wrench where the cups meet the frame. and tomorrom im going to take it to the in laws where i can use a vice. are there any tricks im forgetting? any ways of getting more liquid wrench onto the threads?

    Are you turning them the correct way?

    To loosen the BB, you have to turn the non-drive side counter clockwise, and the drive side clockwise. Also loose then non-drive side first before trying the drive side

    I'm gonna assume that its an internal type BB (square taper, ISIS, etc.)

    You are probably going to need a few more items.

    1. Someone to stabilize the bike.
    2. Your BB tool and wratchet
    3. an extension of some sort - floor jack handle works well.

    One of the few BB replacements I did required 3 people. 1 to hold the bike, and 2 to yank on the BB lockring.

    i believe your assumption is wrong. this image resembles it quite well

    with the tool fixed in place on the cup, i was going to put the hex end of the tool in a vice then use the frame for leverage

    I had a feeling I would be wrong in my assumption.

    what is the frame?

    i just had this problem on my mountain bike. it came out but only after:
    - over night soaking liquid wrench
    - trip to bike shop where it took 3 guys, a propane torch (steel frame) and a lot of muscle and that only got one cup out and the axle (square taper cartridge bb)
    - other cup i was able to get out by using a hack saw blade and carefully cutting the cup without damaging the frame or threads

    not fun

    Have you tried applying heat to the BB shell? Don't use a heat gun, use a hair dryer set on high.

    the frame is an 08 jamis parker. weird thing is the cups in my few year old hardtail came out with eaze. I did get the cups out earlier today, my pops in law had a 30in or so wrench that did the trick.

    Before installing the new BB don't forget to clean the threads in both the BB and the frame. AND don't forget to use antio-sieze or grease on the threads, and torque to the BB manufacturers specs. THOSE little steps will next time faaaar easier!1 Good luck with that!
