I have refurbished a few watches, but I have never had to re-case a watch before. I am having trouble in finding a case of the correct size, are there any charts that relate the size of the movement or dial to a case size? I have searched but I just confuse myself more each time I try.

Almost certainly no such chart exists. Notwithstanding that a lot of cases don't have an ID on to start with, watch manufacturers will have designed their cases to fit their choice of movement-with-dial so there is no need/incentive to have some industry wide 'bestfit' chart. 

Important dimensions can always be found on a great resource like ranfft. Here you can find your movement and its key attributes (click on the Comments about the data link on a ranfft page to get help on what the terms mean if you need to). If you find the dimensions for your movement and then were to find a case that was designed to house a different movement but that has the same (or very nearly the same) dimensions then there's a good chance your movement will fit. The 'wildcard' however can be the dial e.g. the outside dimension of a 11.5''' movement is typically 26mm but the dial on it could be anything upwards of this and vary by several mm from manufacturer to manufacturer depending on their design of their watch..

With this in mind it might be helpful to understand what exactly you're trying to do e.g. what specific movement you have; what is the dial width; and when you say 're-case' are you trying to find a replacement case etc.?

      A lathe with indexing that won't break the bank?

      By JohnR725 · Posted

      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.

      Lab Coats

      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.

      Chinese tools debate

      By Titanium · Posted

      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.
