    "Thank you Quenton
    I was not going to use them but the guy that sold these to me told me I would need them. Can you tell me or even better show a picture of how these are assembled as in dose the screw go through the sheave the a washer over the spoke and then the nut or is it the other way round"


    On the stock Whizzer sheeve the square nuts are on the belt side, and the washer and screw are installed from the other side. The sheeve will have small indentations to keep the washer level and each spoke fits between the hole and raised indentation.

    If you use the brackets, note one has 3 un-threaded holes and the other has one of the holes with threads. The threaded hole is used with a short screw to place even pressure on the spokes sandwiched between the 2 brackets.

    Have fun,

    Nothing like a well thought out installation...
    I agree Terry, thredless is cleaner and stronger than threaded. My Buddy's at the bike shop like to rib me with-
    "If you want to see how strong a new part is, give it to Tommy to ride, if he cant break it, no one can"
    This started before I got into mountain bikes with there there stronger frames and 1 1/8th" head tubes.
    I had a nasty habit of snapping frames and forks on the old 1" head stock road bikes.
    (the later 1 1/4" is even better) As i haven't snapped a fork or head set in some time.
    The total belt drive is a great idea, but ive always been leery about mounting the drive sheath (or rag joints) to the spokes, I know its been done this way since the dawn of M/Bs so it must work, with the right pipe and muffler the bike is going to be very quiet.
    My very first "kit" was a rack mounted, 2 stroke, 25 cc, top mount engine with a belt driven friction drive roller directly underneath the motor, the motor had a 2" V belt drive pulley and the roller had a 5" driven pulley driving a 1 1/2" drive roller, this engine and drive combo was good for approx. 20 mph.
    I was lucky enough to have an electric motor shop near by that specialized in repairing fans and motors for the factory's in the area. They had a huge selection of belts, pulleys and sheaves so I was able to change the power characteristics of my set up.
    Eventually, I blew up the 2 stroke 25cc and replaced it with a 4 stroke 49cc Honda that just ran and ran and ran...
    Oh, it ate rear tires like cocktail weenies, but it ran very well.
    The wide crank set looks great.
    Are those motor plate ends cast aluminum with the center being steel?
    Once you get the left/right alignment right I take it you'll be cutting new slots for fore and aft adjustments to maintain tension on the secondary belt with out an idler, beware the dreaded belt stretch and wet weather, mine used to scream like a banshee once it got wet.
    What is the diameter of that sheath? it looks to be less than 24"s to me.
    Cant wait for pics of the mock up... looking good!

    Well I have done some searching and I have found a guy that sells the adapters for the 1 1/8. SO after I have all my parts if I can manage it I am going to get the Monark. The one he sells is the reinforced version so I am really hoping I can pull it off. Now the mount I have done one already so I would have to say no it is not cast as it is working just fine I am thinking if it was cast it would have come apart by now. Last the rear sheave you have a good eye I measured it and it measures out at 15 inches.

    OK so here is the thing I have checked into the Monark front forks and the only way I can use Monark is if I covert to 1" threaded from 1 1/8 threadless. And that is the only way to do it that would mean getting a new steering head and more costs and I am not willing to go away from threadless so the Monark is out.

    Hey chainmaker
    Yes I did see that earlier but I think you said the quality is poor and if you did not say that then some one else did. Now I have looked at that front end but it just looks like it would make it hard to use the Magno's fender if you know better please let me know as I love the look of that front end.

    Hi [email protected]
    Well what you where looking at is the fuel tank built by Worksman and that is what tank I will be using on this build. If you want to know what the bike looks like there is a big picture of the Magno on the very first page right at the first post.
    Cheers
    Terry

    Cheers

    Here are the pictures of the front drum and WOW it is huge it doesn't look it in the pics but the Sturmey Archer 90mm front drum brake is big
    SANY0319.jpg

    SANY0321.jpg

    SANY0322.jpg

    SANY0323.jpg Again Sturmey Archer and the great hardware includes the brake cable

    SANY0324.jpg This is a pic of the brake levers I got for this rare bird.
    These are old school and that is why I ordered them but they are way too small so I have ordered some mini bike brake levers.
    LOL (RARE BIRD) LOL I just found the name for this build.
    So the Magno's name is now Rare Bird.
    Cool so I will have some pictures of Rare Bird before and after stripping it tomorrow.
    Cheers
    Terry

    Here is a comparison picture the one on the left is the 90mm and the right one is the same size as the 70mm

    Now you can see the size difference
