Kurt,
It is always a possibility. However 61+CM frames are a no no go, and the ones needing repair to the rust on the top tube are also no go's. Perhaps the doghouse and fenders from a 69 Dodge would work. Smiles, MH Gimme a call 812-336-3283

I have an older generation of the Bike Smith press and it works great on both my Schwinn and Raleigh three speeds with cottered cranks. It's worth it if you plan to do you own bottom bracket work on a cottered crank bike. The tool has paid for itself many, many times over in terms of saved time for me.
And I love those "AS&CO" cranks.

I tasked it with a related question.
This is like reading WikiHow when it was really bad. (Not to say it still isn't, but it has improved).
But yay to us - we've invented a system that provides the same vapid advice replies with slightly better grammar -with the added benefit of wasting inordinate amount of processing power and energy to achieve said result.

I think I read all the posts. Did anyone mention that you often need to file the taper on the cotter to properly fit the crank and spindle? I’d like to regularly service my 73 Peugeot but after using a BFH and a 2X4 on it and getting the original set performing as it should, I’m leaving it well enough alone for the foreseeable future.

Victory...?
Okay, in the battle of the tools, it is a split decision. Tool d @Mad Honk versus tool de Treatland’s.
In the NDS crankside, Dave’s tool did well. In the DS, the C-channel actually bent and would not crack the cotter.
In comes the plate steel. After working it, the cotter popped.
The crank is now available to @RustyJames or whomever wishes to partake.

Whatcha looking at? Upon recommendation of someone here, on CR, or iBoB, I modified the one-tooth end of my Park HCW-5 so its inside radius better matched the radius of the Stronglight lockring on my Automoto. If you have a similar issue, let me know and I'll take some pix. Or, you can buy this from Bike Recyclery:
Also, the Stronglight fixed cup was a nearly perfect fit for the 36mm end of my Park HW-2 headset wrench:
Of course, not knowing what you actually have, I'm just speculating that any of this will help you.

and now I have two cool tools (one homemade junkyard special by Mad Honk!) for the zero cottered cranks I will be buying in the future.

No surprise, that metal is just way too thin. I thought it was intended as a joke or prank when I first saw it. (Are we sure it wasn't?) Can't remove a properly-installed cotter, and definitely can't install one firmly enough to be reliable for riding.
That crank isn't really worth putting on a bike. It was near bottom-quality in its day, and this one has slipped at the swaged interface between the crank and the 3-arm spider. Note how the bolt that should be hidden behind the crank isn't quite hidden? Maybe it was just made that way (horrible manufacturing standards) and didn't slip, but either way this crank is not a keeper.
Ooh, I'm such a snob.

The c channel did well when it was seated squarely on the NDS arm.
When it was a bit squeezed on the DS, it must have been awkwardly angled a bit.
the manufactured too also hand a tough time, and the cotter bound the exit side of the tool against the spider...had to back off and pop it off...

Okay, so adjustable cup off...
It actually seems to be British but not sure. No markings but held a Nervar crank which, of the French brands often did English threading.
Fixed cup flats are between 34.5 and 35.5, while the adjustable cup stuff was 25.
Don't want to crank that thing (pun intended) clockwise and it being French or something.
Lock nut should not be able to thread on a British cup if it is French, correct?
