    I hate to break it to you but your going to have to get a different rear hub. The cassete hubs free wheel in built into the hub itself. You won't get that to "Fix" anything short of welding it in place.
    good luck

    Stopping the freewheel from spinning is not my worries, thats what JB weld is for. the metal of the rear hub looks like it wont hold a weld correctly. What worries me is that the freewheel wont spin off when pedaling backwards and if it does then, well, thats what JB Weld is for. malpaq3 and fordfasterr dont make any sense. but thats ok, critics are welcomed. Thanks for posting the link bottlecape30.

    The freewheel comes apart as well, so it can be cleaned correctly and the internals can be removed so the JB Weld can hold correctly. it has a lock ring with left hand thred. i removed the lock ring with a punch and hammer. Ill be making that video next. Ive already got it fixed. Getting ready to size the chain also with a punch and hammer. With a little creativity and ingenuity who knows what you can screw up. The worst that can happen is that i have to buy something

    An electric drill works on a lot of rivets, without having to bang things around with a hammer. A $4 chain tool from Walmart works on the chains.

    I've heard of using JB weld or other epoxy. (Despite the "weld" in the name, it's still just a glue). I have no idea how dependable the finished item is, though.

    Relying on JB weld to hold any drive train parts together is just asking for trouble. If you came up with a way to jam up the freewheel with a bolted in part that would be better. I still think your better off spending 20 bucks on the correct hub, or find a flip flop hub off a junked BMX and spin on a fixed gear. Just my $.02 on this one. I would be very happy for you if you did it safly for nothing.

    i tried to jam the freewheel but the clearances are to tight or i havent seen the solution. where can i find that hub for $20, i thought they started a like 40 plus another $40 for the fixed gear? the flip flop hub is what i wanted to do originally but i havent found a trash bike, everybody want to sell them, and then i will still have to buy the gear. Believe me im pretty worried about the freewheel holding but ill be riding around my house for awhile before any serious riding. i tested the holding strength of the freewheel and it seems like it will. for how long, dont know.

    Hey bottlecape30, can you point to a pic of that flip flop hub so i know what im looking for? thanks for the advice by the way, i can you all the help i can get. i rode the bike for the first time today by the way. riding fixed is totally different feel. Feels much tighter, i think i like it, just got to get stronger legs.

    I have those Sr Custom cranks on my bike
    mid 80s I think thet are. Sometimes has a number on them.
    I would have drilled them myself.
    can you flip the chainring round. so you can get a good chain line. might be ok as is.

    I found i had to use the second low gear on the inside. I just swapped places with the 3rd gear and used the factory spacers on the cassette. i have great chain line and perfect clearance where the chain fits completely into the gear. ill be posting another vid. on youtube here in the next few days. I actually finished the build today. ill be riding it for the next couple of days before i take it back apart for paint. When looking to purchase this hub, is it called just that a flip flop hub? Does it have those threads on both sides? Thanks Mr Dawn and bottlecape30.

    yes should be called a "flip flop hub" because you can thread a freewheel onto one side and a fixed gear on the other. this allows you to flip or flop the wheel to fixed or singal speed. The hub that you are looking for will have threads on both sides. the hubs with threads on one side are generaly for freewheels only, and you already have that.

    a fixed sprocket needs a locknut on it.
    some people ride with out them.
    but it means that the cog might unscrew.

    theres a stepped thickness on the hub. to take the lockring.
    some flip flop hubs are just for 2 different freewheels

    JB welding a bike part = suicide. i would never trust it. that's like building a parachute with fishing wire. get it welded properly or get a regular track hub.

    To make your freewheel fixed, maybe you could remove all the sprockets and drill through the entire mech and wheel together -offset from center so the axle doesn't get damaged - and pin it . you could use a nail for a pin and cut it flush so the sprocket and spacers will go over it and help to hold it in place. Might work

    Maybe with JB weld, but not red loctite. My beater fixed has a "Suicide" hub put together with red loctite and a BB lockring and I trust it for skidding and skipping more than the Formula hub on my good bike. Still have both brakes on both bikes though.

    Hub in question;



    Old Formula freewheel hub with a fixed cog and BB lockring red loctited and rotafixed on. Solid as hell and regularly beaten on for over a year now. No slippage or signs of any. This is also a "free" fixed gear, meaning it put it together outta junk i had lieing around in my garage.
