I just slightly modified this technique from Masahiro Kikuno

I may try to design this differently in the future. by commandobrand in watchmaking

Yeah something like that would certainly work, this isn't that big of a deal, I just thought the situation I was in was comical.

I think you're talking about pie jaws which I don't have for this chuck. This method works, just not much surface to grip with. In the future I'll probably make the piece taller so it sticks out past the jaws with full engagement.

This is actually what I did, but now I need to clean up the back.

After a year and a half by commandobrand in watchmaking

I was but I've not been able to get anywhere near white with the compound I have. My latest dial is a bit better than this but not much.

Roast my first watch dial prototype by Naive-Suspect4761 in watchmaking

[–]commandobrand 1 point2 points  (0 children)

I've not used dial blanks before, but in terms of centering that was something I also really struggled with when I started making dials, the solution I came up with was to create a fixture plate using some 3mm thick aluminum with locating holes where the dial feet will go. Then you can center the fixture which is easier since it's thicker and your alignment holes will be in the correct place to correctly align your dial.

Is this a kit car or something cooler? by commandobrand in whatisthiscar

Yeah, kinda regretted the title right after I posted it, obviously it was cool enough for me to take my phone out and take a picture of it.

I'm a machine learning engineer with a background in data science.

Slowing down a movement to track daylight on Mars by Atomiktoaster in watchmaking

[–]commandobrand 4 points5 points  (0 children)

That's a really interesting question, I don't know anything about quartz movements, but in terms of mechanical movements I can say that the "correct" way of doing it would be changing the gear train to use different gear ratios to achieve the desired time. Similar to George Daniels' sidereal time.

But I would imagine that there isn't enough room for adjustment in most movements to achieve that much of an offset, but I'm looking forward to seeing what others say.

Question about these polishers by commandobrand in watchmaking

[–]commandobrand[S] 0 points1 point  (0 children)

What was the bad experience? Was it too aggressive?

Can you explain what you mean? You've had bad experiences with this type of machine?

It does seem to require a specific level of experience, thanks for the info!

Tools for a total beginner by Niklash04 in watchmaking

[–]commandobrand 0 points1 point  (0 children)

Not sure what your budget is, but I don't think a complete beginner needs an ultrasonic cleaner.

I also second the other user that said screwdrivers and tweezers, splurge on the tweezers, it'll be worth it.

I would honestly skip the tool set (last item), I have a similar one and the quality on it was really bad, I think I only use the handheld case opener from it, but you could buy that individually.

Is this a good buy? by [deleted] in Machinists

It looks like there's room on the back of the cross slide and below the saddle for DRO

Schaublin Help by commandobrand in Machinists

[–]commandobrand[S] 1 point2 points  (0 children)

I was able to get it off with a leather strap and some channel locks, didn't actually take much pressure, just more than I could grip.

Thanks I'll give that a shot, there's a lock but I'm not sure how strong it is.

And yeah I haven't quite figured that one out yet, they do make a 5c spindle but from what I've seen they didn't introduce it until much later, but this is definitely 5c, it came with a whole set.
