    hammer and chisel.
    bash it or yourself really hard until it feels fixed.
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    You might as well buy some tools. Opens up option to using bunch of cool cogs, hubs, or wheelsets. I use "Shimano TL-SR22 1/8'' Chain Whip". It is a little costly but it does cogs and lock rings in one package. I am pretty sure it isn't a Shimano thing. You can get cheaper one I recon.

    I am pretty sure you won't look cool if your cog fall off on the road.

    All that work to save $20 on a real cog?

    C'mon you gotta value your time more than that.

    well, he would need to buy a freewheel remover tool.
    then need an adjustable wrench (unless the cheapskate magically has one)
    then need the cog and lock ring (assuming he has a hub that has the opposing lockring thread)
    then he would need a lock ring tool to make sure the lock ring is securing the cog on.

    But that avoids the question of how to be stupid and defy all common sense like the OP asked.

    remember kids, there's no such thing as a stupid question....

    ...........just stupid people who ask them.

    ouch! twice in one night! that don geezee is a total c.unt

    If you are referring to a cog that is made for a splined freehub, then there is basically nothing (cheap) you can do to make it fixed without totally destroying your hub. You need a new wheel.

    If you are referring to a thread-on BMX-type freewheel, you need a freewheel remover tool and a really big crescent wrench (or bench vice) to remove it. Once its removed you can thread on a fixed gear cog and thread it on really tight using the rotafix method.

    Nope. That looks like a 10-speed rear hub converted to single speeder by moving spacers and gears on the cassette. A pretty smart idea, but I would have gotten spacers so I don't need to use any gears. ... So cleaning is easy.

    You might want to google for a suicide hub. Should turn up a lot. (You see most of these are just single-speed hubs fitted with track-cogs without "proper" lock-rings) But it doesn't do you no favors. Your backpedaling experience is gonna become extremely risky, so inevitably less fun.

    As for welding cassettes, you find an article here.

    http://www.63xc.com/mathieson/cheaphub.htm

    But I read some place that cassettes aren't tough enough for "fixed" riding. ...

    Yeah, for Maximum Fixed Pleasure, you ought go get a track wheel set. No hustle. While you wait for the wheel set, you can settle with the tweeker. But it might be waste of your time.

    1. Wrap your chain around the freewheel and hold it with a Vice Grip.
    2. Take a needle nose plier or something similar, stick the prongs in the little holes on the freewheel cover and open it up.
    3. Mix up a batch of epoxy. Fill the entire freewheel cavity and replace the freewheel cover.
    4. Keep your rear brake.

    Disclaimer: I've never tried this nor do I know anybody else who has. It's probably not any worse than some other things that haven't killed me.

    I consider myself pretty open to hack jobs, but this one just does not make sense. You can find a super-cheap stamped cog for about $11. There is no way you will save $11 in materials, grief, failure, and work with any of these plans. Cheap cogs suck. But a cheap cog will be infinitely better than any work-around.

    IMO any FG conversion that does not use a proper FG hub, or a properly FG converted casette hub, is dangerous. The torque transmitted to any FG converted freewheel when slowing down or stopping w/o brakes will try to unscrew the freewheel from the hub and without a lock ring as, used on a proper FG wheel, it will probably happen eventually. The same is true with installing a FG sprocket on a regular freewheel hub that does not have provision for a left hand threaded lock ring.

    Using household items...

    Freewheel dismantled and cleaned of all grease, then filled with JB Weld. Let harden.

    Then clean the freewheel threading on your hub and apply JB Weld to it. Screw cog on and mash up hill/chainwhip tight.



    Now after this fails at the worst possible moment (hopefully not resulting in death), go buy a proper wheel/cog/lockring.

    welding sounds like the best, depending on the metal how strong will the binding be between the metals? strong enough?

    Seriously, I doubt it. I'm wondering how the heat expansion is going to affect how the parts thread together.

    Just curious, who do you know who can weld a steel cog to an aluminum hub? ...because this guy/gal's advances in metallurgy will probably win them a noble prize, or at least millions upon millions of dollars.

    JB Weld is the best stuff EVER......just not for this application. Go out a score the proper parts. A home built hack job is a nosebreaker waiting for a place to happen.

    I have a pile of ruined hubs from attempting to make ghetto fixed wheels a long time ago. It never ends up working and WILL FAIL at the worst time (emergency stop/mashing up a hill/in front of Swedish bikini team/etc) and YOU WILL HURT YOURSELF.
