Another shiny object!  LOL.  I could not resist pondering a 3D printed solution for some of the parts.  I don't have the plans...just taking a SWAG at what I see on the youtube videos.  Here is one of the slides.  The mate for the slide is a trivial design and print as well.  I just quickly laid out this piece.

I would think a 3D printing system would be a perfect platform to make this and other repair tooling. I've worked with them on occasion and find them super fascinating.

It is one of the most utilitarian tools I have other than a screwdriver.  I have repaired many things around the house by printing replacement parts.  I have also created many tools and add-ons to other tools.  There is a huge repository of designs that others have done on the internet.  I love to make my own stuff--do the 3D design but when I find someone has made what I need, I download and print!!  Below I show a picture of a 3D printed fully functional escapement that built three or so years ago.  It is a wonderful demonstration of how the escapement works.

I own a Ollie Baker mainspring winder and also a home made one made out of wood and a converted mainspring winder. Both work great the issue to be aware of wood changes in shape as it ages and changes as it takes up or looses moisture so it looses its original smoothness in operation. The issue with the Ollie Baker is you are required to hold the barrel with one hand while winding with your other hand. I got around this by making a various sized wood clamps to hold the barrels see pic below for both my hand made winder + the Ollie. I know my hand made winder looks crude but be assured it works and is better and safer than trying to wind springs by hand.

Hi  I like the way that you have modded the spring winder, I also used the let down tools as fit the spring arbour properly. As for looking crude the fact is it works and it overcomes the problem of holding springs by hand.  The wood if and when it becomes less effective can be replaced cheaply and effectivly.  I used mahogany for the clamp its good and hard. A Great idea, engineers answer to a problem based on what you have available. I for one think its brill.  It May inspire others to do something similar.

Thanks yes it works but it is not the best engineering for sure. The clamping system I use is really good when dealing with either small or large mainspring barrels. The key to working with mainsprings is having control.

      Stem removal after fitting hands

      By Neverenoughwatches · Posted

      So leave off the seconds. Stand the movement on its edge, its the dial edge that rests on the pad ( either rubber or cork , something that wont slip ). Use a finger of your left hand to hold the movement upright,  right hand presses the release and flicks out the stem. I do it this way so i can see what I'm under a microscope. But you could hold the movement between two fingers of your left hand, its the right that has to manipulate the stem out by pushing the release and flicking out the stem with  right ring finger nail. Sounds more complicated than it actually is. I guess you could fix a push pin to something solid, then all you need to do is push the release against the pin, leaving your right hand completely free to pull the stem out.

      Try putting everything back together and closing the back cover. I think one of the two springs has to contact the metal casing to ground the casing. So when you press the button, it will touch the contact on circuit board and close the circuit.

      Yes, the seconds hand is the longest and goes almost to the edge of the dial. I can’t quite picture it how you do it on the rubber pad

      A don't think so it leaked or damaged it because the watch itself works it just the buttons ain't working not connecting with the circuit board have taken more pictures of where the buttons makes contact with the circuit board.

      I think what peter means oh is once he has fitted the hands and  checked for  alignment if them and that they dont foul, how does he then hold the movement to remove the stem in order to case up. The dial cannot be laid on a cushion or in a movement holder as the hands will get damaged. This can be quite tricky for a beginner, what i do is  to stand the movement on edge on a rubber pad so it doesn't slip. Hold the top edge with one finger then my dominant hand uses 3 fingers to press the stem release and flick out the stem. See below peter, leave off the second hand as this is the longest and gets caught the most, then fit it once the stem is out. Alternatively place the movement in one of the cup style holders, i imagine this is what they are designed for. They only touch the very edge of the dial.
