Cotter Pin Tool
Going through my stash of some old English bikes. All need maintenance on the bottom bracket and some of those old crank pins are NOT cooperating. I've done the usual Kroil, hammer and punch, floor mounted buck, and so on. I knew Park made a tool for pin pressing which is the way I want to go. Are there still some out there used or new? eBay is my goto but esoteric bike stuff is far and few between. Thank you.

Thanks, great link! They also have a cup tool that seems handier than stacked washers on a bolt. I've got 2 that aren't budging yet.

...he used to have a deal where if you bought both the cotter pin press and the fixed cup tool, there was a discounted price for the combination. It does work pretty well, but it's still pretty difficult to extract some of those fixed cups on old Brit bikes, especially Raleigh's. I would advise cleaning and inspection in place. To remove one of those unless you need to replace it is work, and better spent on other things.

My current bike project has both cups stuck. Thanks for the advice and some ideas I've already tried. After 40+ years mechanic'un, I've had my share of work arounds. I've seen even with the right tool, some jobs are still a PIA. (Pain In the Arse)
Bikesmith stuff will be on it's way. One thing I consider is many of my tools were bought used. If the day comes that I hang up my wrenches, I can sell them too like the guys I bought from.

Looks like this project has a sad end. The backstory is I acquired this bike, Raleigh? Robin Hood, new in 1965. It was my 1st and being in the country miles from the nearest town; it was my ticket to the world at large. Logged a lot of miles until I got a driver's license. I was scrupulous on maintenance though washing road dirt wasn't top of the list. It was last used in 68/ 69 and stayed at my mother's place until about 2010 when it went to a storage unit. Couple of years ago we brought it out here in the hopes of maybe using it again, nostalgia I suppose.
Some critter's seed storage in the bottom:
However then I saw this:
That was NOT how it was left in 1969. It is a very light frame so I figure some sort of alloy tubing. Dang! Maybe wall art now.

Sad end, but it looks like it was used by someone with a loose sidestand.
I had to remove a cotter pin from one of my bikes this week, a hard bike to work on as it appears to have been assembled by a gorilla - even the head of the cotter pin bulged out. After a week of trying to remove it the usual ways I decided to saw off the head to make it quicker to drill out. The vibration of the sawing actually freed off the pin, as I discovered when I gave it one last chance to come out with a G-clamp.

Same situation for my R20 project - no tool and the "C" Clamp did not work either. If you have a bench vice - Try that instead put a large socket on the non threaded end and crank away! This of course was after a few days of soaking it with a rust blaster product. It really made a very loud POP when it gave way...
