I can find faults with all of them. Never use a re-bushing tool. The chap re-busing a carriage clock. If you use the reamer correctly it will self-centre in the hole, all this hold it like this and push it the other side is rubbish. If you use very large reamers as he showed you, a little lube such as oil and you will always have a perfectly round hole. Never bush from the outside, always from inside the plate. When you need to tap the bush in place put it on a block and with the correct size flat punch tap it in, the way he showed, you could miss and hit the plate causing a mark and as it’s a carriage clock and the movement is visible it will always be seen. The customer will not be happy, you have de-valued the clock. I never liked pre made bushings. I preferred to make my own by measuring the plate, pivot and oil well, making it, I knew it would fit properly and would not be seen. A movement that is visible and re-bushed correctly, you should never be able to see the work.
