I forgot to say... you don't have to remove the blueing, it doesn't do any harm to the bearing, it will wear off in time. I ALSO forgot so say, the bush will be annealed so don't use it for bushing after!
Thanks. I have followed all 50 of your pendulum clock classes. They are excellent but here you have it in one! An absolutely vital video for any enthusiast in one short clear lesson - and your answer below to harden or not (not needed as blue is OK) finishes the lesson. Thank you so very much. Simon
My new favorite clock repair channel. Really interesting video. I wish I had seen this before snapping the bent pivot on the escapement of my french clock which has now been sitting there for months until I find an economical way of repivoting it.
@@howtorepairpendulumclocks Ive got a unimat lathe. I recently bougtht the watchmakers spindle which came with about 10 collets. I had a go at making something called a top hat but I failed. I dont know itf the unitmat is too powerfull. I'm ok at general restoration and have a channel (treetopspider) where I carry out full restorations but I am a a very new beginer to clockmaking.
@@treetopspider The unimat shouldn't be too powerful. The problem is controlling the speed. If tools are sharp and you can somehow keep the spindle speed down you will make progress. Keep at it! Thanks again for the positive comments. Matthew

Peter, that is another great question and one I should have covered in the vid.. The answer is if you have controlled the tempering process with the spirit lamp, you see how I keep taking the Arbor in and out of the flame to keep things slow, and the pivot has not gone beyond blue, you do not need to re-harden as the pivot has not been softened, only tempered. If you were hardening, you would have to temper back to blue anyway. If you lose control of the tempering or mistakenly use one of those micro-torches and it goes over blue to pale blue/grey/white, I suppose in an ideal world yes you would re-harden and re-temper. TBH, that process would be more damaging than the relatively soft pivot. I think even if the French clock type pivots were tempered beyond blue, they remain relatively hard i.e. not entirely annealed. Hope this helps.
