Awesome work

 

You've posted 7 times- and this is only your 7th? And you come here to show us this?

Bravo sir.

It may be rough- but you can always finish more. You've done more than most have now.
I thought of a 6497 the second I saw this. I see I wasn't wrong. You had solid carbide gear
cutters made- I don't know of anyone doing that. Where did you go that was able to make
such exacting cutters profile ground in carbide for something like this? Not many people
specialize in pantograph grinding stuff that small, but I could be wrong.

Never heard of anyone cutting dead hard pinions like this with carbide cutters- very
unorthodox method. It worked though.

Very cool- what grade of titanium did you use for your cage? I thought of using some
6AL4V ELI I have laying around- but thought finishing titanium to horological polish
standards might be a special nightmare.

We demand a detailed post on this one. Give us the whole story. You can't just show
up with a handmade tourbillon and not give us the whole story!

Ondrej Rough or Smooth: it's still your baby. Let's see how things progress. Good luck! Regards, MTF

This looks excitingly promising!

Thank you very much for sharing this milestone with us - I guess you fulfilled yourself a dream? As for the video, I'd suggest you upload it to youtube and then share it here. Youtube offers a sharing function which creates a HTML code line you simply cop... 

You are right

it is a fulfilled dream and my baby. I did some very stupid stuff and had very stupid ideas, but as far as things turning out from stupid ideas go, this is probably the best one so far. here is the working video... or should be, i can't embed it, no matte... 

Awesome work

[OT] finishing titanium

 
By: DonCorson : September 6th, 2015-02:12
Hi Ophiuchus, I don't have the tables with me, but 6AL 4V sounds to me like type 5 titanium. It polishes without problems, I use platinum polish. Pure titanium, type 1, is way too soft to polish, the more the titanium is alloyed the harder it gets. Have f... 

"Pretty happy" ... you master understatement...

That is amasing work Ondrej. Of course we want to see as much as you are willing to show us. I am impressed by the pure and simple design of all the parts I see. It is obvious that you have been thinking about how to make this for quite a while and have f... 

Well,

ok, i know pretty happy is an understatement, but i wasn't going to open this with saying i cried like a little girl when this thing started ticking :) Anyways, thank you all for the kind words, although there is still a whole lot of work ahead of me, i f... 

Nice, very nice.

Thank You for sharing, I to would love to see more. Kind regards Anthony

Here's what i could think off

 
By: Ondrej Berkus : September 7th, 2015-09:24
that might be interesting to see. Also, thank you for fixing the video. Much obliged :) Here's my lathe i was talking about. Pretty standard lathe with two modifications - dividing plate (can be seen leftmost of the picture) and a plate to mount a millin...

I fall off of my chair. The high priests of watchmaking barely dare to attack such stuff. Did you say you are a professional watchmaker working since ?? how many years ??? Ondrej, your work is amaising. Congratulations that your perpetual is working I kno... 

Thank you,

but, after seeing your watch building threads, i think you are the last person to fall off a chair seeing my amateur trials. I've seen what you can do, your work is amazing. I am not a watchmaker, let alone a professional one. I have been making knives fo...
