Just taken this to our LBS and he doesn't have the tool, so I may as well buy the tool myself (or, as he suggested, cut a groove for a chisel in then tap it round). Anyone got any idea what tool to buy and where from? It's from the early 60's. The other side is different but the LBS says he can get it out once the cup below is removed using an expander tool thing.
I have a feeling a pin spanner would be the "correct" tool but also a feeling that they would be less than useless, based on previous experience with them.

Undo the grease port, pour in nitroglycerine, hit with a hammer
There's nothing other than a pin spanner that will work AFAIK.
I'd be sawing flats in it and getting it on a vice.
It is seized, yes?
I think you would be quicker getting a tool made.
Flat plate with holes and hard pins.
If you don't want to re-use the BB ,you could even tack weld it on and then [b]THWACK[/b] it 🙂
cut the axle so it drops out (assuming it will and isn't held in by races on the axle or sumink), tap the pin holes put in screws so thety are 10mm proud of the face and use a bar to turn?
You've already removed the lock-ring from that right?
If so, the remaining cup should be loose. It's the one used with a pin spanner to adjust the bearings.
If it's seized, the usual remedys apply. Heat, oil, brute force.
Filing flats and putting it in the vice or welding it are last resorts, but the most likely to be sucessful. Good advice.
Actually it might be easier to take the other side out first if you can?

The lockring has been removed.
The axle must be saved unfortunately, it's a non-standard size and I need it for the replacement BB.
Removing the greaseports is also proving problematic as they don't fit anything in my spanner set!
Al- not sure if it's seized as I don't have a pin spanner, however I'll buy one then have a crack and if that doesn't work move onto the more "brutal" suggestions in the thread.
what you need is a tool like the Tune or Royce one, but with the correct pin pattern, if if doesn't easily undo with a pin spanner I'd be getting a tool made and doing it properly before trying more destructive options

Have you tried using a punch in one of the pin holes to see if it might budge ?
One already looks a bit opened out.
fasthaggis- I'll try that tonight. Or sneak out the office now and do it in the car park...
I should add that this must be done by the end of next week as it is going to be painted and must be back, painted and built by the start of September for a wedding. How quick could an engineers make a tool do we think?
If it's seized I'd do a variant of something suggests up there ^
Drill a couple of the weedy pin holes out and tap to M8. Put a couple of grade 8.8 bolts in and use them with a bar between to twist it out...or weld the bar on.
Yeah I would try a punch and hammer.
If that's steel in steel I'd be getting a torch on it until it loosened off
Punch in hammer worked nicely- didn't think it'd have enough purchase but that side is now out, thanks.
The other side is more problematic but I whacked it twice before thinking "I should make sure it's not Italian threaded". Do we reckon a British built bike marketed as a "lightweight" from the early 60's would be anything other than British ISO thread?

A bit of decent flat plate,dowel pins and a reamer .
If they like you _30 mins 🙂
Italian is bigger diameter I think - just check the diameter / thread in the cup you've removed. If it same as a regular BB then I'd guess (?) the other side will be a regular LH thread.
weld a log bit of angle iron on to the cup to give plenty of leverage

It will either be the current 24tpi or the age old Raleigh 26tpi.
Won't be Italian.
If you don't have the proper tool for the DS a BIG nut and bolt through the cup will screw it off as you tighten it.
What are you using for new cups?
The LBS can get a new BB for it, minus the axle. However the cup has come out neatly so I may try and reuse them.
