  1. Is there a special tool for chainring bolts. (not the allen wrench side,
    the back side) Usually they just stick while I turn with the allen wrench,
    but sometimes they do not. I can often just put a screwdriver in one side
    of the little slots, but I have a pesky one that is mounted behind the arm
    on a Sugino SD crank and I can't get to it.

    There is, it's called a chainring bolt tool. Park makes one, and I used to
    have a really neat Campagnolo version.

    This one is really nice:

    That is a nice one but doesn't solve the OP's next problem, of the
    hidden spider arm. In my experience they're impossible with any
    chainring nut tool.

    My Campy chainring nut tool actually had a low enough profile to cope with
    chainring bolts/nuts hidden behind the crank arm. Now if I could just find
    that little bugger...

    sure:

    but if you grease the bolt, while leaving the nut side dry,
    it doesn't seem to be needed. I use that tool when removing
    old bolt/nut sets which spin in the crank.

    Not quite impossible, though nearly so. I have a skinny tool from Park
    that will fit, and I do have Sugino cranks as well, so have real-world
    experience with it.

    A good idea when re-assembling is to put something sticky between the bolt
    and the ring, as well as using grease or anti-seize on the threads.

    Shimano part number TL-FC20.

    It just may be compact enough to get between the crank and the ring.

    Also useful for removing the 4mm headed screws that used to hold
    cassettes together (before they went to rivets), and crank bolt dust
    caps (the old ones with two holes).

    In addition the TL-FC20 has a 9mm hex hole that I've yet to find a
    good use for.

    Brake shoe nut. When alu shoes were lighter because they used stud and nut
    fixing.

  10. I noticed A Muzi (Yellow Jersey) has a link to his shop showing the
    Sugino tool for $1. That is one of the best (beats the Campy version
    big-time because of the little blip in the middle), and it is unbeatable
    for the price!!! (Let's see, I believe mine is approaching 30 years of
    age now...)
