Hello everyone, I am new to this site and new to vostok modding as well. I hope everyone is having a good evening. I would like to share a little tool that I made today for polishing and or sanding the cases on the vostok watches. I got a little bite mark on the case from the bezel tool when I was taking off the bezel on a 150 case. I want to put a satin finish on or maybe bead blast finish. I have not tried it yet but I think it would be nice to be able to rotate the watch when working on the finish weather you are sanding or bead blasting.
Chuck it up in either a drill press or a drill in a vise and let er rip!.

I got around to trying the case back mandrel out today, I had to use a variac (Variable auto Transformer) to slow down the drill to about 120 rpm.
The speed control on my drill was not working very well.
Here are pic's when I started. I cut strips of scotchbrite into strips held them taught. I was surprised how little pressure I had to use to get the desired effect.
It took me longer to do the sides by hand than it did to do the top.

I think the next time I do this I will glue the scotchbrite to a Popsicle stick. I got a little lite scratching on the side of the case. I think gluing the scotchbrite to a Popsicle stick will make it more ridged and more accurate instead of being so flexible.

It's a great idea and it works well for Vostoks Amphibians who do all share the same back-lid connection. However there aren't  that many watches who are so versatile and have this luxury, that you grab a back-lid-tool which fits many different (style) housings. Plus spare Amphibian back-lids, to make a tool, are cheaply available & in mass.......

      Omega cal. 565 - low amplitude

      By JohnR725 · Posted

      as you took the mainspring out what did it look like? It's amazing how much amplitude you can get if the mainspring actually has the proper shape. last week I was doing a 12 size Hamilton and was very much surprised with the beautiful back curvature the mainspring had. Then the watch had a really nice amplitude the group would be so proud it was 350 until I dropped the lift angle down to 38 that drop the amplitude quite a bit below 300. then with the beautiful back curve it still had really nice amplitude the next day. I really wish all my mainspring's look like this as the watch had beautiful amplitude the next day. So many of the aftermarket pocketwatch Springs I see now do not have anything resembling a back curve may be a slight curve and that's about all. They still work but they just don't work as nice as a properly made spring. then Omega as all sorts of nifty technical documentation unfortunately every single corner is watermarked with where it came from who downloaded it etc. very paranoid company. On the other hand I will snip out images like from the document on recycling a mainspring barrel. for instance here's the section on what your mainspring should look like. water damaged a lot of times means rust was there rust on this watch?

      Hi all

      Welcome to the forum, enjoy. It’s highly unlikely you will be able to purchase a new bezel look on eBay for a pulsar watch for repair to find a bezel.
