If you’re like me, it’s nice to have someone willing to poke around a big community like ours and find the most interesting stuff. Saves time and I hate missing something great. It worked really well when we had someone discovering the best photos for the home page rotation back in the day. And if you have something fascinating to post, maybe this email does everyone some good by getting it noticed. Let us know what you think when you get it. Your feedback will make it better as we go (thread). Thanks! Baldy & rudy1220

    Rebuilt the 35 mm Better forks on my SWM and had to drive the damper rod out it was that tight. Both legs.....
    Seems like the fiber ring on the damper rod has swollen over the years. Does anyone have a lead on where to order just this part? Or any suggestions for replacement --

    I did try filing down the ends to increase end gap and reassembled, but they make a lot of noise moving up and down...

    Try the Bultaco parts suppliers. You could also turn down the groove that the ring fits into.

    PTFE rod, that can be milled to the size bushing you need, a bit delicate to handle.
