In this video I use my new Seitz Jeweling tool to replace a jewel on one of the plates. The reason for this is I purchased a new ratchet wheel and the pivots were too big for the existing jewel. This watch is a very nice Chinese Clone so not all the parts are to ETA spec. Grinding down the pivots was not an option so I mined 50 Russian watch movements for the right jewels. Found the first one in 20 min and replaced the jewel. The second one on the main plate took two hours to find as I looked at and disassembled many watches. Here is my video for anyone who try this out. First time using this tool as well.

Thank you for the video and the time you spent doing it. I realy appreciate it!

 

Do you have a higher resolution version? ;)

Had to strip down the movement again to get the plate out with the other jewel to replace9f9c5cf32bda1ba240ef2c1b285292b4.jpgd2285217237897524afcb2cd3a362e78.jpg
Here is the plate with the old (too small) jewel on the upper left and the new (Russian watch) jewel on the left. Next step is to clean the jewel and plate hole and then press in the jewel.

In the picture of the movement, the small red marker dot on the movement is the jewel that needs replacement. I pushed it out with a 65 size pusher.

    • Hello and welcome to the WRT forum.
    • interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.    
    • Use a Portwest Howie lab coat. They are the biological type so they have tapped cuffs so you don't end up getting the loose cuffs of normal lab coats catching everything. 
    • Some of the Chinese tools ae great and can be purchased at a fraction of the price of Swiss ones, some are complete garbage and some I'm convinced are coming out the same factory as the branded ones.
    • I found this string about this problem. I've not gone through it all, but I believe it also mentions making a spring. If not in this string, the info is online.
