3D Printed Mainspring winder, does it work?

Recommended Posts

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.

Looks promising but my worry would be there durability. Having said that the cost of these would make them attractive for hobbyists. More R&D required. 

Durability would certainly not be on a par with anything professional, nor useful for a heavy use environment or where reliability, repeatability and consistency was required, BUT, given the printing time, paltry amount of filament it requires and space they take up you could have three of each size you use sitting in a drawer.
It's not quite good enough yet but i'll be fettling and trying to get it better.

      I am working on a Bulova 11 BLC movement and trying to source a new replacement mainspring, does anyone know where i may be able to source one?

      I'm trying to release the tension in the mainspring on an Elgin grade 144 pocket watch and unlike my grade 291, this one has a hidden click and the main barrel is tucked underneath a plate.
      I've looked online and found a single forum post stating I need to push a pin or very small object into a hole underneath the main barrel (which there is one) while simultaneously holding the stem in place to stop it from unwinding all at once.
      The problem is, I've got a single screwdriver that fits in this pinhole and after poking around in a few directions, it doesn't seem to be releasing the click. I don't know if this is the right hole (it is the only one) that I'm putting it in, if it's supposed to be on a specific angle at insertion, a certain depth, etc. I've attached photos of the side of the movement and a diagram of what I am doing.
      For what its worth, its a lever set.

      Hello Everyone.
      I need some help with repairing my Emporio Armani ar-1922.
      I've watched some videos on YouTube but none of them resemble the movement of this particular watch.
      My first problem is removing the stem/crown. I cannot see anything which looks like it will release the stem and I don't want to poke around inside it any more for fear of creating any damage.
      Any help will be much appreciated.

      WRT Members,
      I have a 50's/60's era Waltham men's wristwatch that needs some help.
      It's in amazing (as-new) condition, but while wearing the other day, it stopped - even though there should have been plenty of power in the mainspring.
      Disassembling for investigation quickly revealed the trouble. The screw-head from the ratchet wheel screw had broken off and found its way in to the train wheels and locked everything up.
      There appears to be no other damage - thankfully. But now I want to fix the movement. My preference would be to find a barrel arbor and screw - or better yet a complete going barrel assembly new with ratchet wheel screw.
      I am search eBay now - but thought I'd check with you guys to see if anyone knew of a good source for such parts. I haven't found any yet.
      NOTE: This movement is Swiss made, 7 jewels, marking on the base plate look like Unitas 1690/02
      Any info/help is greatly appreciated.
      Kind Regards,

      Hi everyone, hoping I might be able to get some advice on re-assembling my watch movement.
      Working on a Bfg-866 movement from an older watch I got as something to practice and attempt to fix. I disassembled it and managed to get the arbour back in it's rightful place in the mainspring, which fixed the winding issue I had had with it. However, on putting the movement back together I got the train wheels all in place and made sure they could all move smoothly after fitting the wheel bridge back into place, however when I try to test wind it without the crown it would wind up and add tension, but nothing would move and the spring wouldn't unwind. I don't have the pallet fork or anything else in while testing this, and double checking everything seems to move smoothly, and the mainspring wheel had a tiny bit of play side to side, seeming to imply it isn't caught on anything either. Am I missing an obvious issue here? Feel so close to having it working and any advice to get it going is much appreciated (Apologies for any part naming mistakes, still pretty new here. If I can get this watch to run, as it so nearly did before these issues, it will be my first successful repair, hence my eagerness!)
      Thanks in advance

    • Oops, didn't read carefully enough. Thought 5134 was the calibre number.  Here's a complete list of what CousinsUK have to offer for Patek cal.215 :
    • Let me be the 1st one to welcome you to the friendliest forum in the world. I'm not sure why your post is not receiving the love from our usual welcoming party. Perhaps everyone is out partying after being lockdown for so long.  There is no such thing as a dumb question here. We are all here to share and learn. I've asked enough dumb questions in my lifetime to fill a whole room. May your hobbies fill your life with endless hours of enjoyment. 
    • For the price asked seems like learning how to make (CNC or not) this kind of parts may be a killer business. 
    • The 215 is a quite common movement for a Patek Philippe, but as with all expensive watches the replacements are expensive too since they aren't mass produced.  Here you got one at the bay selling the wheel you ask about, the rest of the parts are out there too. https://www.ebay.co.uk/itm/Patek-Philippe-Geneva-Cal-215-part-1x-under-crown-wheel-420-diameter-3-4-mm/133217216347?hash=item1f045d675b:g:ywkAAOSw4bhcJQ0P
