i didn't mean for people to get all uppity, sorry about that.
i am always willing to share what i know from experience.
on to the self-made tools:
the easiest but most useful so far has definately been this
headset cup remover, its just a pipe with two cuts and is
slightly pryed open.
chainwhip is also fairly easy, mild steel, mark holes, drill,
attach chain via master links or better yet with the link pins.
(please excuse the blur)
the lockring wrench was a biatch to cut. i used a bandsaw,
but its hardened steel; mild steel is ok, but not as durable.
so, i didn't make this, but this is what i use to press in headset
cups. i did make one once using a long piece of all thread and
washer and bolts ...someone else on the forum did the same thing.
this obviously isn't a tool, but before i got some mks chaintugs
i made this one. its pretty crude, but it won't break and it does
the job.
ps. yeah, some of it is rusty ....its terrible i know.
