Singlespeed fettling saga, episode 27:
I repaired my chainwhip ready to have another go at removing the stuck-fast lockring. Broke the chainwhip again. Repaired the chainwhip again but STILL can't get the damn lockring off! I actually chiselled off one of the spacers to try and loosen the lockring but it didn't help... I reckon the problem might be due to corrosion.
It dawned on me that pouring boiling water on the lockring will probably make it tighter. Perhaps I could try freezing it?
An alternative might be to bypass the chainwhip and clamp the sprocket in a vice. I don't actually own one though... It would be quite a handy thing to own so I might buy one.
PS I had a flash of inspiration - I used a Mole Grip instead of a vice to hold the sprocket. Result... the damn lockring still won't budge, but at least I am not re-re-breaking the chainwhip! I am using such a ridiculous level of force now that I am worried that I am going to wreck the wheel or injure myself if something suddenly slips or breaks. The next attempt may involve the use of a hammer! Either that, or get someone else to hold the Mole Grip so I could try standing on the 12 inch spanner, or use something long and strong to extend the spanner (scaffold pipe!?). The lockring tool is starting to deform under the load so that itself could break.
