Greg,
Tried to PM you on this but I don't have enough posts.
If you like, I could send you my cotter pin press to use on your bikes.
I can just weld up another one for myself. I only have one bike with a cottered crank so it doesn't get used a lot. I enjoy making little tools for working on my bikes and this one turned out to work very well.
If you could still use it, just send me your email/contact info.
