Well, all the gear teeth have been cut...
Tomorrow I am going to try and start popping the teeth waste out. I think that will go faster and be easier on my arm than the sawing. I am really looking forward to this step.
Things to note about this gear.
* I've mentioned before that the gear may not work because it has a few slight problems. If that is the case, I'm not too worried. I had always expected that the first gear would be a throw away. It does not mean that I am not going to try and make it work just that I am prepared for it to not work.
* I need to get better about having a nice smooth, finished surface before I start trying to mark out and cut the gears. My biggest problem with cutting was that the lines marking the cut points were not nice and clear.
* A divider (compass) works perfectly for laying out the teeth. An article a few years back in the Antiquarian Horological Society had suggested some alternate techniques. Quite honestly, the techniques are overly complicated when the divider method works just fine. I have to disagree with the author on some of his suggestions.
* Overall, it takes about 15 minutes to cut 4-5 teeth. This means that if I was a full time smith and my arm was able to take the sawing, the largest gear could have been cut in about 5 hours. I am sure if I was practiced and once again in the proper shape, that time may be cut down to about 3 hours. I think that this technique was probably the most likely technique used.
* I went through about 3 saw blades to cut this one gear. However I think the steel may have been partially hardened in a few spots. If I was using period materials, the saws would not be as high of quality but the gear would be wrought iron which is very soft. I have some wrought iron and I may do some testing to do a comparison.
* In the future, from my new experience, I would expect to be able to produce the gears much faster.
Cool. It's good to see clock progress again.
ReplyDeleteIts good to be making progress again. Over the years it seems I go through periods were not much happens then suddenly things start getting done. I'm glad to be working again and I have some good photos to post but Xanga is doing some maintenance right now and its not letting me post photos.
