Interesting. Did you ever replace the cartridge bearings? I would keep it if I could . It’s not in terrible condition so might use it initially but I don’t like the fact I can’t service it without the 4 pin tool. Just waiting to hear back from lbs to see if they have the tool. If they don’t surely someone in London will
I definitely don’t think I have the skills, equipment or patience let alone the time to make my own tool
Never replaced the cartridge bearings, but from memory it should be a simple job.
Someone in the London area should have one. Sadly a few older shops I could have recommended are no longer about. I bet you Condor would have one, but you might be miles from them?
Making a tool is easier than it sounds. You would need:
A random piece of plate steel or aluminium (body of the tool)
Dowel pins - you can buy from eBay in small QTY's (for the pins)
Pistol drill (for drilling the holes for the pins in the plate and one for the BB axle)
HSS drill bits (as above)
Centre punch (marking out for accurate drilling)
hammer (for hitting the centre punch)
Grease proof paper (for transferring the position of the holes on the BB cup to the metal - a bit like brass rubbing)
Pencil (as above)
Hacksaw (cutting metal plate to shape)
Adjustable spanner (for gripping and turning the plate)
Large washers & crank arm bolt (for holding the tool in place)
I guess that list looks quite daunting!!!
