- This tutorial from the ClockClass DVD selection, "Repairing Damaged Teeth," shows a technique for replacing a missing or damaged tooth, an important method of gear restoration for antique clock movements.
Дуже важливо знати, дякую вам за працю 😊❤,є чому повчитися у вас
could some new metal be brazed onto the gear and filed to shape instead of dovetailing a piece on ?
The problem with adding material in this fashion is that you must heat up a large area of the brass. This will anneal the brass, making it soft and easily bent, which isn't a desirable result. Dovetailing in a new piece of brass, and then using a low-temp soft solder to secure it to the wheel, is less likely to cause the brass to become soft. Great question and thanks for asking!
No mention on soldering it. Is it hard solder.
Hi Stephen- Thanks for your question!
These short "teasers" can't fully cover the topic like the full DVD can. The DVD is 1 h 20 min long and is available here: www.abouttime-clockmaking.com/ClockClass/Repairing_Damaged_Teeth.html
However, I believe your question was answered in the public reply to lendusaquid.
Thanks will get the dvd soon.
😍😍😍
Any videos on repairing bent spring barrel teeth like on a seth Thomas sonora chime unit barrel.
Hi Will- I just reviewed the DVD "Repairing Damaged Teeth" and it doesn't specifically cover straightening barrel teeth. However, the principle is the same... Gently warm the area with a lighter. Use a flat screwdriver to pry and lever the tooth straight. The blade should just fit the space so you may need to use several different screwdrivers. Check the root of the tooth for any fracturing and replace if fractures are present. Good luck with it!
@@clockclass5480 Thank you I'll need it are there any avenues for purchasing a new barrel ?
@@willf5768 Yes, About Time Clockmaking has a large parts inventory and does have some ST Sonora chime barrels. However, a barrel would need to be pretty far gone for it to need to be replaced. It would be better to replace a tooth, or five, rather than purchase a new barrel.
@@clockclass5480 Well this one has three teeth involved bent from bad to really bad there is a bulge at the barrel spring hook area and someone before has done some filling around the cove so I am assuming it's been apart for some reason. I had called a repairman that has been in the business for many years and his quote to repair the eye of the spring and the barrel teeth was $400.00 about what the clock is worth maybe. I can probably fix the barrel and the spring but don't have the means to safely remove and install the spring which I was told a bear of a job without a heavy duty spring winder. And I kind of concerned with the reliability of the barrel to be honest.
@@willf5768 The high repair price is because of the dangerous mainspring, I'm sure. However, all of the damage is repairable with the proper techniques. I routinely repair bubbled barrels, re-end mainsprings, install new barrel hooks, and repair/install teeth but I completely understand your concern about a repaired barrel performing reliably, especially considering the size of the mainspring. Good luck with your search for a replacement barrel and let me know if I can help further!
