    no matter how fun a project is, sometimes ya just get burned out.
    i could tell i was starting to loose steam on my build off bike. so this is my build off, burn out build. :)

    i'm sure you know, yesterday i was at the brantford vintage bicycle show. too much fun! way too many cool bikes and well it inspired me to build. this is just a quick side project. i don't want to take too much time away from my rrbbo entry.

    picked up a schwinn xr-7 a couple weeks back.
    [​IMG]
    i wanted the sprocket for my bbo entry, but without changing the frame, it just wasn't gonna happen!
    little did i know!
    its been sitting in my back yard ever since.
    yesterday i managed to get on old schwinn frame for $10 and the idea was born.
    [​IMG]
    use up those gosh darn exercycle parts!

    so heres the concept, schwinn frame collides with xr7
    [​IMG]
    [​IMG]
    this is just another "using up what i got kinda build" ratty in it's truest form (well imo at least)
    i love the giant sprocket idea. think i'm gonna go bigger and include the chainguard!



    started by drilling out the rivets in the flywheel to seperate the two 1/2's.
    inside i found a metal weight and black rubber edging. (which i might still use)
    to my surprize the flywheel fit right over the one side of my shimano 3 speed hub.

    [​IMG]
    and its almost a prefect match to the rim (if i use the black rubber seal, it fills the tiny gap between rim and wheel cover)

    [​IMG]
    the sprocket side on the otherhand is gonna need some fabrication, but i think it will be well worth the effort.

    even with a huge shim. the main sprocket still rub's the frame. yup we're gonna have to mod the frame just a little.
    [​IMG]
    whats that you said? is that a 1" threadless headset on an old schwinn frame? how does he do such wonderful things you say
    well todays your lucky day, i'm gonna tell ya. :)
    ya use your dremel to take a little off the race, a little off the headtube (inside)
    ya throw the race in the freezer, torch the head tube and very very gently, ya beat the heck out of itwith a hammer (and a block of wood to protect your investment.) :)
    [​IMG]
    the forks are a set of triple trees from a cheap canadian tire full suspension bike.
    the fork tubes themselfs are just stainless tubing with my custom flame drop outs (built a while back)
    the xr7 speedo is coo also
    [​IMG]
    [​IMG]
    all the xr7 parts are top notch due to a life indoors. its supplied me with all the bearings/nut's/bolts etc that i need, all in almost new condition.
    if it stops raining, perhaps i'll bang this one out. later i'll use it as a platform to practice some pinstriping.

    i've been thinking, with a giant flywheel in the back (this is heavier than most wheel covers)
    3 speed gearing and no real place for a decent set of rear brakes.....
    this may very well be a "killer build" :shock:

    but on a positive note, that sprocket thing, weren't no thang at all! :)
    i just had to cut enough room for the dust cover. there was practically a perfectly placed circular
    impression in the steel . just followed it with a dremel sanding drum.
    [​IMG]
    some foam tape (they sit on the spokes) and a handful of ss nuts n bolts is all i require!

    LOVE IT!
    I was wondering when a large chain sprocket was gonna appear on here from you.
    I noticed it wasn't on the Skull-o-sis "yet". :lol:

    buddy you have no idea, how much i just wanted to cut the frame on skull-o-sis, weld it back up and have done with it. that sprocket would have looked at home on skull-o-sis. was gonna knock myself right out of the build off.
    >< this close i tell ya. had to fight every ounce of my being to play by the rules and stick with the program.

    man am i glad i did. almost like fate things didn't work out and i had all the parts i needed for an old stripped schwinn frame. didn't even have to go looking for em. they were right in the back yard.
    had i of known, i probably wouldn't have left the spotless crank sitting outside in the rain for a week. oh well a little polishing to do.


    btw, i'm allowed to change bikes once for my build entry, right? :lol: :lol: :lol:

    that is just plain sick. you should use the rear wheel weight and a drop stand. imagine getting it on the stand spinning it up then drop it off the stand i am thinking burnout lol. love the lines of this bike it just works

    no just one wheel disk (2 halves)
    [​IMG]
    i'd search for another, but 2 i think would be a little heavy.

    couple quick pic's of the clearance issues i had to deal with
    first, i had to grind one 1/2 of the wheel disks to fit over the sprocket side dust cover.
    [​IMG]

    also had to make room for the crank sprocket. ratty engineering at its finest. (heat and beat!)

    put the rubber trim back on the wheel disks. its a flawless match and seat up tight against the rim.
    they pinch the rim tight and should allow me to use the fly wheel as a breaking surface.

    How many teeth is that front sprocket? Good thing you are using a three speed hub. This is monster!

    that would be a 64 tooth front sprocket. :)

    this was a pretty straight forward build (pick up parts in the back yard and assemble.) :)
    i don't know if its an rrbbo contender, theres some off the hook builds this year.
    none the less, i appreciate the comment just the same. thx bud!

    so heres your chance to get your 2 cents in on my build.
    i hate picking bars, i have so many here and they can drasticly change the dirrection of the build.

    i've norrowed it down to 4 options i have on hand.
