Santa brought me a tourbillon made from plywood and toothpicks

I don't think I can afford the 9010 for that.

Luckily it comes with a tiny candle to wax the relevant parts. I'm not sure if it's made of solid 9010 or what 😉

OK. You've piqued my interest. Tell us about the quality of the kit, please.

I have to say, overall I'm very impressed. The instructions were very good and easy to follow. Having a knowledge of how a Swiss lever escapement works definitely helped when putting together and tuning the tourbillon though.

Getting the mainspring in and wound properly took several tries, and was probably the most frustrating part.

Once it's all together, the parts do need to be lapped in. The instructions say to turn the tourbillon for 10 minutes by hand, but I found mine needed a lot more running time once it was assembled. You just have to wind it and keep giving the balance a nudge when it gets stuck on the pallet fork.

The real issue I had was with part of the tourbillon coming apart while running. I'm still not sure if it damaged anything, but I did use a little superglue on some of the more important parts when I rebuilt it.

It's far from a Swiss timepiece, but it does have beat and rate adjustments, and it really looks cool spinning around on my desk.

I found it on Amazon, and looked over the reviews. Clearly not a watchmakery crowd. One person said it would run for a few hours after it's been run in for a while, but most were stuck around 2 minutes or less (user error from the sound of it). How long does it run under competent hands?

I wish I knew, but under my hands it seems like a few hours is about right. There is a lot of friction in the system, and it doesn't seem like the mainspring has a ton of reserve.

But then I've never timed it, and it may change as it wears in.

90 minutes since winding so far, and it's still going strong. One thing I do notice is it runs very fast, even with the balance spring as long as I can make it. It's gained 10 minutes since winding it.

But again, I don't feel like it's meant to be a chronometer. It's a super cool desk toy.

Edit: stopped just over two hours. A nudge of the balance wheel got it going again, but it seems like the mainspring is running out of power.

So it's not a clock so much as a cool contraption.... Bummer... Seems like a lot of finessing could make it work well enough for what it is, but if it can't run for at least a day and change, it can't really be a clock per se.

    • That's the right technique Mal 👍 If you are ok with a loupe ( which I'm not ) then pick up the dial in your left hand and make a tripod holder out of 3 fingers and then exactly how Mal and me described with your right hand, press and flick out the stem at the same time. You need three fingers to do this, i use my ring ring finger , sounds like mal uses his little finger, just whatever you feel comfortable with. The key point and dangerous side to this is the tweezers or driver slipping off the release screw. Stablise your left arm by resting your elbow on your bench, so that you can hold the movement horizontally flat, use a x5 loupe to view  and good light so you can see well and have a good tight fitting screwdriver to push the release down. Or as suggested a pusher mounted solid upside-down somewhere then all you need to do is push your movement up to it. I'll rig something up in a bit to show you what i mean. Something like this, but tbh its better to just learn to do with your fingers.
    • Thanks Michael, shes a real soldier, it would take a tank to knock her off her feet.  Shes surprised even me and i knew she was a tough cookie.  Good for you Michael, you keep at it. I've been reading your posts re. your watchroom they're inspiring and it doesn't matter how long it takes you to get there its about the journey. Rome wasn't built in a day, our watchcaves are our solitudes, our own little empires where we can shut ourselves away from the crap that goes on around us in the world. I look forward to seeing you progress, I have my own ideas how i like to do things. But in answer to your questions on that thread, just let your workspace evolve around you and how you work. You wont figure it out straight away but you will know when to change it and when to leave it alone. But most of all just enjoy it.
    • That can be tricky. Sometimes I hold the movement from the edges in left hand and with right hand I push the release with tweezers and simultaneously pull the stem out with right hand pinky or something. 
    • I see what you mean. I must admit I’m not entirely comfortable with that but I can’t see a better method than what you suggest. I’d like to see something like this mirror with a short spike: https://www.cousinsuk.com/product/mirror-for-observing-movements Place it on, push the spike on the post with one hand and release the stem with the other hand. Minor problem, it doesn’t exist.
    • Hope you mum keeps on mending. I was adamant that I was going to get myself going after my stroke. I was only 52. I still have a lot of life left to live. Some people give up. Some people don't let it beat them. Your mum sounds like one of the winners. 👍
