      Hmmm, kind of!
      But........ It shows great potential as a hobbyist alternative, with some tweaking.
      After a back and forth with @Andyhull on another thread it got me to thinking perhaps it's not as useless as my initial annoyance led me to think, (I broke a mainspring trying it but to be fair the spring had been previously abused and the tool wasn't ideally sized allowing the coils to jump and tangle).
      I had a bit of a resize with sanding stick and scalpel and tried again and it's certainly got promise, I need to tweak the file to suit specific barrels but it's a simple quick 3 part print using barely any filament.
      Obviously not anywhere near as good as the proper bergeon winder but definitely cheaper for the hobbyist, (even if you haven't already got a printer and had to buy one first).
      Here's a video of it if anyone is interested, comments and ideas are welcome.

      Good (insert time here) everyone!
           I am relatively new to the world of clockwork repair and maintenence, but have done delicate metalwork, mechanism cleaning, and enjoy fixing things. Just recently, my sister brought home her boyfriends late great grandmothers singing bird in cage automata. For those of you who dont completely know or understand what it is, its basically a spring driven mechanism using bellows and a variable organ pipe to make bird sounds and move a little birdie around and "sing" (Example of singing bird mechanism working).
           His aunt wants it to be operational again, and after opening it up (not yet taking much apart) I have come to the conclusion that it could just use a good cleaning and oiling. But, my question is, what kind of oil should I use and how should I apply it? I don't have any fancy oils except for a bottle of valve oil for my trumpet at my current disposal, but I would like to buy some decent clockwork oil for this project and a sankyo music box repair I have waiting. 
       
           Note: come to find out while writing this, it was made by eschle reuge I'm Germany, probably around the 50's or 40's.

      Currently having limited space to work on watches, I decided that a portable desktop workbench would be necessary for me. I was inspired by this blog post for a similar sort of DIY setup, but was having trouble finding good sources for the individual components. Instead I used the following parts (mostly ordered from Amazon but available at Home Depot and Target as well):
      Carlisle CT121623 Café Standard Cafeteria / Fast Food Tray, 12" x 16", Gray 1x IRIS Desktop Letter Size Medium Stacking Drawer model DTD-L (available in clear or black) 2x IRIS Desktop Small Stacking Drawer model DTD-S (available in clear or black) Velcro 90087 Sticky-Back Hook & Loop Fastener Tape with Dispenser, 3/4" x 5ft Roll, White Everbilt #12 x 3/4in flat head phillips wood screws (SKU 284 773; from Home Depot) I paid about $32 for all of the above. Interestingly, everything except for the wood screws was made in USA. The plastic drawers do come with clips that allow them to be attached together, but the connection seemed pretty weak (hence the wood screws).
      To construct, I drilled through all of the holes on the bottom of the small drawers where the rubber feet would be pressed in (and ultimately ended up removing the Velcro you see in the picture below because I went with the screws instead):

      Next, I applied a bit of Velcro between the front edge of the two small containers. This may or may not have been necessary with the screws, but I did it anyway!

      To attach the two small containers to the larger drawer, I removed the top panel of the latter, marked where all of the feet align, and drilled some more holes so I wouldn't crack the plastic by driving the screws through it. You'll see where the two front inner holes interfered with molded plastic, so I didn't use screws there (also why I used the Velcro in the picture above).


      The screws may poke through the holes somewhat, but they shouldn't interfere with the drawers.

      Next I used a utility knife to shave the low feet off the bottom of the tray to make it smooth, then marked where it would be centered on the top of the small drawers. And in case you had been wondering, I chose to use the tray because it was cheap and had a decent lip around the edge to prevent things from rolling off.

      I then cut some lengths of Velcro in half and applied them to the topside of the small drawers. When I first ordered the Velcro, I hadn't planned on screwing it all together. The idea was to make it disassemble-able, but I changed my mind. Alternately, the Velcro could be replaced with double-sided 3M foam tape (though that wouldn't be thick enough to bridge the front gap between the two small drawers in the second picture.

      And now the final product, all stocked up! Esslinger's Watchmaker's Anti-Static Bench Mat Work Pad fit pretty darn well on the tray, with a little extra space around the edge to set things that might roll otherwise. The drawers have no locking mechanism, so make sure they don't slide open during transport. They do have some tabs to prevent them from falling all the way out, but that probably won't help much by that point. Final height is 7 13/16". The tray itself is textured, so a vacuum-clamp vise like the one in the blog post would likely not work.

      Hopefully folks find this useful. If you want, you could always stack more drawers. I find this size to be work pretty well and easy enough to store in the closet.

      I've been looking for a forum like this for a while. My Minorva Tourbillon watch has a hand that fell off. Now this is not the time or place to discuss the ups and downs of of purchasing an inexpensive tourbillon watch. However I do like to watch and love to have it back in my wrist. Issue is I cannot get the movement out. I opened the back and was unable to remove the movement from there then I was advised to try to get the moving out from the front but I'm having real problems getting the front bezel and Crystal off. I've attached some pictures they're not the greatest, I'll upload some better ones if needed but any help would be appreciated here. Thanks in advance.  I thought about forcing the crystal out with air pressure, because all I need to do is just access the front of the dial. However then I realized it if I pressure the front crystal out the back display case will probably pop out first.

      As I'm progressing in my knowledge from just being able to regulate and adjust to minimize beat error I've been looking at the 7S26 that I have with my Seiko 5 beater watch. I've heard numerous mentions of being careful that you don't break the plastic gears, particularly in vintage watches.
      There is a solution for that. With a bit of CAD skills you can print replacement gears and parts. The cheaper filament based printing isn't precise enough but laser based SLA can print features down to 100 microns it should be sufficient for all but the tiniest parts. More than just gears and components it can also be used for custom tools within the limits of the materials used.
      The Form 2 is the printer I would look at unless you want to step into commercial pricing.
