Hi there. You can use a drill press for reaming providing that you centered the hole first by hand which unfortunately Is not in this video. And yes it is recommended that you use a smoothing broach afterwards, however the clock will run for many years without it but the smoothing broach is the recommended practice. I was not using smoothing broaches at the time I made this video but I am now. I am learning too.

Great video learned allot about hobbyist not needing expensive bushing tool machinery. But now I need to know exactly what to purchase to repair a single bushing pair. I can accumulate addition tool sizes as bushing repairs are needed on my collection of Mantel Clocks. So minimum would be? I have digital caliper and small harbor freight drill press and I guess your cutters are Bergeon? would need the tool that holds the cutters, whatever that is called or would the cutters just be used with the standard drill chuck on drill press, I need 2 specific bushing CUTTERS based on pivot measurement, I could use larger drill bit instead of CHAMFER, need WIRE DRILL SET 0-60 maybe Huot , maybe 4" PVC coupler to hold plate on drill press, a specific size five sided BROACH, an aluminum or steel rod for PUSHER. and the 2 BUSHINGS themselves, can they be purchased individually or do you purchase a whole set or a small set of the most common used for Mantel Clocks? I guess the bushings all have an undersized hole that has to be drilled and broached to the size required? Is that about it and where would I purchase the tools, Timesavers, Ebay?? Sure appreciate your videos and advice.

Hi Larry, Yes my cutters are bergeon. I would suggest for a standard antique mantle clock you would need a 1.97mm, 2.47mm, 2.97mm and a 3.47mm cutter. You can purchase a bergeon reamer adapter for drill press at timesavers. That's what I use. I would buy a small set of 5-sided broaches. They usually come in a pack of 5 from size .77mm to 2.27mm or similar range. With these you should be able to bush any size hole on a mantle clock. You can order individual bushing sizes for each of your cutters in 10 or 25packs usually. I would get one set for each cutter. Make sure you gradually cut up to a larger size hole. Also, you want to use a bushing size OD that is 2x the size of your gear pivot OD. So if it is a 1.5mm pivot, use a 3mm bushing. I buy most of my tools and parts from timesavers or micromark. Hope that helps.

I saw something on Timesavers that may be an inexpensive alternative for us virgins wanting to try this bushing install for the first time (truthfully, I'm getting somewhat discouraged with all these different cutters, reamers, broaches, etc. needed): it was a clamp on for an electric screwdriver to keep the reamer true when drilling the hole. Why wouldn't that work?. It was $46.50 compared the price of a drill press, not to mention the price of those bushing machines

You mentioned that the hole was worn and needed to be bushed. What you didn’t show them was how you compensate for an oblong hole to make it dead center again after it’s bushed. I put the Plates together when reaming and use a broach that goes thru both holes to make sure the hole is dead true and perpendicular between the plates. My opinion is you oversized the hole for the pivot and will wear out sooner and could cause a depthing problem with each gear that engages with the bushed gear. The thickness of the bushing isn’t determined by the plate thickness,nits determined by the length of the pivot. If upon checking the end shake you see the pivot doesn’t protrude the bushing then you need to use a shorter bushing or sink the bushing to the point of just barely uncovering the tip of the pivot at extreme end shake and end mill the rest of the bushing from the back side of the plate. Having a short pivot in a long bushing will cause endshake problems as the pivot wears. You do a good job otherwise and everybody’s technique is a little different but the end result is to have a properly bushed pivot in every aspect including the depthing of the gears involved. I’ve got 55 years at the bench and am a Certified Master Clocksmith with AWI. Installing a bushing is very important, as I have come across many a botched job in my years. Do you also have videos showing the assembly after the bushing procedure is complete? This is usually the deal breaker with any novice as there are many challenges to making sure every cam, lever, pin is in the proper place in order for the chime and strike to properly function. I think what you are doing is good in fact to the inexperienced person who thinks anybody can fix a clock, as it shows them that leave this to the trained professional if you want the job done correctly. I have received basket repairs where the whole clock is in every state of partial bad work and not assembled because the customer bit off more than they imagined. 😮

Sorry, Patrick, but you are also wrong. The wear is not directly from the weight or spring except on the first wheel. The forces are directed from each wheel to the pinion gear of the following wheel. Thus, the direction of wear alternates in direction and is NOT at the bottom of each pivot hoke. In fact, the wear is likely not even perpendicular to the bottom, but opposite the direction of the force applied by the wheel teeth to the pinion leaves. Sorry, but YOU have misled many new people.
