I don't have a set of the proper size reamers for bushings. I don't do enough clock repairs to warrant buying a set in my case. As such I use cutting broaches to get the hole to the proper size. One of the things I do for getting the size of the hole right for the bushing is to carefully slide my caliper after setting it to 0.03mm under the bushing size and then locking it down with the tension screw up the taper on the broach cutter until the caliper touches on the cutting edge and place a sharpie mark around the cutter on the thicker side of the broach. I place the sharpie mark and check it under the microscope. One thing I've noticed with the set of cutting broaches that I have is that the dimension across the cutting blades is slightly different for one pair of the opposing blades than the other so when measuring I will turn the cutting broach 90 degrees. Which ever pair of cutting edges has the larger dimension is the one I use for the measurement. I find this more comforting, faster, and less stressful because I can work my way up to the mark while focusing on keeping the cutter perpendicular to the plate. Everything else I do the same as you demonstrated. If the bushing is close enough to the edge of the plate to allow me to reach the bushing with my staking tool, I use that to drive in the bushing instead of free handing with a flat face punch. I work on watches far more than clocks so I have watchmaker's tools.

With the brass plate worn out of shape, say to one side, how do you find true center, before starting to rebush hole ?

Thank you. I'm very interested and hope to be doing this to my cuckoo clocks before too long. I'm now in the process of acquiring all the necessary tools.

Great video, I enjoyed it very much. Thanks

0:22:30 Thanks for this video. Do you use a smoothing broach inside the new bushing to address any imperfections left by the cutting broach?

thank you very much for showing me how to do it by hand, i dont have a lot of money and i wanted to know a way if you could do it by cutting broaches, now that i seee its possible, i am gonna give it a try, altrough if you cut to far you are basicly a lost movement and cant be fixed i ghuess???

Schow US THIS !!!!! Cklok AT work wer is IT ? ? ? !

I wish you had shown us how to ream out that last bushingl After pounding it that hard, I don't think you'd get any pivot into it. It looked completely peened over!

Thank you for the interesting material! Did you change the opposite bushings in the second plate also? I heard it is essential to provide a correct alignment for a pivot.
