Movement Screw Head Alignment

 By: enjoythemusic : December 17th, 2021-20:13
As a self-admitted OCD type, I admire drawings where the movement screw heads are all aligned. So my questions are, does any mechanical timepiece manufacturer actually do this, and if not, how hard could it really be? ...  

I read these, if it helps

Why Screw Slots Aren't Aligned In Watchmaking

Good reads...

Both articles are nice, and as sad as this sounds i thought about this years ago and did enquire to a manufacturer of this possibility. While it does add labor, how much depends on the 'organization' of the screws. It would mean indexing screws delivered ... 

Anything is possible...

 By: mdg : December 17th, 2021-21:04's just a matter of 'how much.'

I could be wrong but...

I count 19 screws in this illustration and only 12 of them are aligned (at about a 45° angle). So even an artist who's not actually screwing them in is only at about 36% accuracy. Maybe it really IS difficult in practice...

Exactly! I've seen some phenomenal craftsmanship.

Wonderful pic, thx for posting! Very much admire the very high level of attention to detail.

Seems rather hard especially for the "gain".

Considering classical screws. Normal assembly is the mainplate that is threaded with the bridge on top maintained through a recess with the screw head. Let's consider an S1 (1mm diameter screw). The pitch is 0.25mm. This means that one single hundred (0.0... 

Incredible Knowledge!

Seems you've given this thought. Wow, it is quite the challenge! Great post, all help is appreciated.

The larger the screw, the better (like in a gun/ rifle or bigger), but movement screws are small plus fragile and the more you over torque them the more they deform the slot to the point of actually breaking below the head. The fact that slotted and heate... 

Excellent Points

You are right of course, at these 'micro' levels there's a higher chance for undesirable material deformation on either side of the mating. Many great posts on this thread. Maybe it's a materials-based solution on the bolt side of the equation. If the ass... 

It’s definitely doable but is a lot of work and time consuming.

This gentleman has done it with his knives and this cigar cutter. Just exquisite workmanship. ...

Yes Indeed

Yet i think that would add height to the assembly (?).

On a larger scale, imagine a car chassis with all screws and bolts aligned

Don’t think it’s possible? Bills hot rod Shows us that it can be done. Cazalea

Yes! WOW!!!
