    I can't ride until I get a frame, so I've been spending time fooling with the parts that may soon be on a trials frame. I don't remember who it was exactly (Josh perhaps?) who made the direct mount derailleur, but it inspired me to try it too, perhaps to improve upon it.

    I started by pulling the derailleur mounting bolt, spring and washer out. I measured the I.D. of the back side of the empty space...it's about 18mm. So I drilled it out with an 18mm bit to give it an even bore.

    I was going to have a friend machine a new washer for me to glue, press and bolt into the derailleur. He's going to get it done, but for now, I used the sanding drum attachment for my dremel tool to mount the washer for my fun bolt. I turned the dremel up all the way and ran the washer up against a flat file until it was just too big to perfectly fit in the derailleur.

    Once it was the right size, I used JB Weld to epoxy it into place and then used a dead blow hammer to push the washer into the derailleur.

    It's done for now.

    I'm considering drilling three holes, tapping them and using 6/32 x 1/4 set screws to reinforce the washer. I think I'll do this temporarily, until I have the new washer ready for mounting. The new washer will have a flange that will sit outside the derailleur so the King funbolt will essentially clamp the der onto the hub/frame.

    I had fun making it, we'll see how it'll hold up once I get my new frame.

    flame on.

    Damn, if you're implying what I think you're implying, that's pretty harsh...especially since I can't even wheelie up a curb yet. :rolleyes:

    Reminds me of the Germany video where the mod rider hooks that many pallets to rear.

    What the fuck happened to this thread.....I'm honored someone is trying the wacky der modification.You also need to serrate the back of the der/waher /frame interface so it grips well.

    Your looks a hell of a lot better than my drunken construct!
