    I have had john brain's page saved forever
    (a couple of years at least :D)
    it is very well written/thought out
    I just don't have the confidence in making one with the simple tools I have access to :(

    At the least you'd need a decent-sized drill press to do that.
    Trying to do hand-drilling in thick metal is just ruining drill bits to make crooked holes.

    A drill press is always a good investment; - I'm really glad I got myself one. Waaaay easier than swinging around on the end of an electric drill. :shock::smile:

    Here's a fork I built with some of John's plates.

    I used his designed plates and improvised on the rest. As you can see I made the lower spring mount resemble the rocker arms so the look of the fork would "flow" a litttle better. The rocker mounts are also different that John's (they're not just flattened with a hole drilled in them). The rockers have plastic washers on either side of them so they can be tightened down to reduce lateral slop but still move freely. The spring bolts slide in bronze bushings so the action is butter smooth with absolutely ZERO friction or binding. The top plate is held on with star nut like the ones in threadless headsets.

    It is a well thought out design and John really did his homework. It's worth building a set just to see how nice they can be.

    Sianelle, that's awesome. Could be easily fabricated at a hardware store. I have been pondering a stock spring forks set-up.

    Butch, same here. Am dang curious.

    those searspringers are really cool ! :D
    I may attempt to replicate them myself :)
    looks like the hardest part would be getting springs of the proper strength

    I picked up a whole lot of trampoline springs while I was at the rubbish tip recently and I was going to try them to see how they would go.

    The local engineers' supply store here in town does have some springs too, but I haven't really been to have a proper look yet.

    Some great ideas in this thread. That Majestic Ball Bearing Spring Fork Attachment looks so simple. And it gives me some ideas for some interesting variations.

    Ah yes, - during the solid tyred safety bicycle era many many patents were filed for suspension systems. There is truly nothing new under the sun and more than likely the trick full suspension system on the flashy MTB in the shops was already thought of before back at the end of the 19th Century. :grin:
