Movement holder made with 3D printer


Recommended Posts

I like the well-known brass movement holder for doing work, but when I have a movement in the "waiting for parts" mode, it is nice to have it sitting in a nice stable holder.  So, I decided to print this movement holder.

Print time was 20 minutes.  Probably took me about that long to design it.  Now that I have one complete, I can tweak it for other movement sizes with only a few minutes of effort.

FYI, this is a Landeron 51 chrono.  I cleaned it and it is running fine, but I need hands and a decision about the dial.  I have a dial, but it is in really poor shape.  I see hands and dials on Ebay, so I just have to decide which one to commit.

This type of holder should be so sligly undersized so to grab thanks to a slit in the diameter. And when is for a chrono mov.t all the difference is made by having pushers.

Will you publish it on Thingiverse or perhaps just attach files here?

I am attaching the Freecad file.  I use Freecad which is open-source software that is heavily supported and it is FREE.  Been using it for three years and love it.

 

STL file also attached, but it is not as useful because it is much harder to edit.

When I get some time, I will parameterize this for easier mods.

My son owns the printer, I just feed him the drawings and he works his magic. I'll see if I can get any advice from him and pass it along.

Thanks!

I use a Lulzbot Mini which I bought about five years ago.  Have been very happy with it. Print ALL the time.  It is a little pricey.  I suggest you consider a Prusa.  The product line is well received and is very economical.

Good work on the holders, I am printing the 2 for 1 now.

Hope you like them 🙂

Anyone have any 3D stuff they have made that would be good to share, I asked on another post about movement holder rings for Seiko (not dial spacers) but nobody has responded

Sorry I don't have a separate file for each holder, I sketched them out and my son drafted them for his printer. I have now forced myself to learn the software he uses, but these were done before that. I'll see if I can get him to split them out.

Here is an update on the movement holder.  When I store an unfinished movement in the popular domed parts carrier, it tends to flop around if I try to place it in the center.  The solution was to put a base on the holder that sits nicely in the center partition.

I have a 3D printer on the way and am playing around learning FreeCAD. This looks similar to what I will be trying for my first project (movement holder that fits in the hand setting tool). Could you post the FreeCAD file? I'd like to see if I can adapt it to what I am trying to do.

 

By the way, your movement holder has that 'ledge' that is below the top of the holder which the movement rests on when in the holder. When you designed how thick the ledge is and how far down from the top it is, did you get those numbers from measurements you did on the movement or is there some other way you decided on those numbers?

WRT does not support FreeCAD file types.  PM me and I will attach to my reponse (if it lets me), or we will go offline via email.

My design was a simple hack more or less.  All measurements except for the width of the movement were SWAGs.  You will see in the FC file, I created a spreadsheet to parameterize the elements.  The extra piece on the bottom to fit the movement holder was also an "addon" hack using the Part workbench.  It too is a hack...lol.  When exporting to stl, you have to select two sets of elements.  If I were to do it over again, I would assemble the whole thing using Part Design workbench.

Thanks, I'll send you a PM.

Wow, great minds think alike, I use freeCAD and also have a 3D printer being delivered by Santa 🎅, I currently have to bribe my son to use his. I was was thinking on Friday afternoon that it may be cool to try some parametric modelling in freeCAD and sketched out a parametric movement holder. My idea was to measure the movement outer diameter and then let freeCAD spit out the complete design.

Here is what I sketched in my lunch hour (including a doodle I did whilst on a very boring conference call) on Friday:

holdersketch2.jpg.6143123ae8885119aa056be816cb26ed.jpg

I also plan to put a fillet (0.25?) on some of the outer 'corners' mainly for aesthetics, and one on the entry to the seat to make it easier to get the movement in, but didn't get time to add them to my sketch, blue circles above.

 

Also l1  is the cutout for the stem/crown, was thinking of making it U shaped rather than square, but would model it as a square and simply fillet the corners to make it a U shape.

Just in case you can't make out my handwriting:

d1 = variable (the movement holder OD and the only input you need to make)

d2 = d1 + 10 mm

d3 = d1 - 5 mm

d4 = d2 x 1.5

r1 = h2

l1 = 10mm (with 2mm filets{?} to make it a U shape)

h1 = 5mm

h2 = 30mm

h3 = 5mm (will only need this outer dimension also to be h3 if I decide to keep the 'shoulders' at the top of the model, thinking I may just skip the outer shoulders and have the top and bottom linked by an ark without the shoulders... I will need to think about this....any ideas??? My initial thinking is that the shoulders may flex a little as you push the movement in and grip the movement better, but not sure how realistic this idea is?) - see version 1 and version 2 below.

Once I get to grips with it, I'll post the freeCAD design on thingiverse and you can also PM me for it from here 🙂

Think I did it.....

Below  is my parametric movement holder (size 30mm movement)

Below is size 10 mm movement (minimum size before model breaks):

Below is size 70 mm movement (maximum size before model breaks):

And here is the Parameters table - only need to change the red text cell at the top:

PM me if you want the link to download 🙂

This is in FreeCAD not sure if it will play nice if exporting in other formats, but I'll give it a go if you let me know what you need.

I think I managed to create a link you can download the freeCAD file:

    • Hi Fernando, read carefully what @eccentric59 wrote, it is the key to You problem. Lubricate the cannon pinion. Take care to understand what is it's function. When You set time, the train doesn't move, but only the cannon pinion moves. Put hte lever back in it's place, it has nothing to do with time setting
    • Hi fernando. Let us know how you get on.
    • OK, in You case You will assemble the movement with the line attached to the barrel and fusee and will  wind the line  entirely on the barrel after that. It is important when replacing the line to know the correct lenght of the line. The rule is that when line wound on the fudsee entirely, about 1/4 turn still to remain on the barrel. Yes, no tension. The ratchet is not placed yet, the spring in the barrel is complitelly unwound. At the end of the step the fusee is empty and the line is attached to it and strained perpendiculary to it, not on tangent. The escape wheel. Use whatever that will not damage anything. Yes, this is typing mistake, sorry. The word 'pendulum' here is not correct, You should use 'anchor' and yes, it is removed from the movement at this point, according my instruction 1 (Ihave used the word 'lever' there):   Ok, let sey the barrel arbour makes 6 full turns when winding the spring in the barrel from unwound to fully wound state of the spring. Let sey that the barrel makes 4.5 full turns when winding the clock from fully unwound (the line is on the barrel) to fully wound (the line is on the fusee) state. This means that You should not wind the spring in the barlel when adjusting the initial tension to more than 1.5 turns of the arbour of the barrel.  If You make 2 full turns, then when winding the clock, the barrel will be able to turn to only 4 turns, so the limiting device will not limit the rotation of the fusee arbour and You will be able to force the line much more than when the limiting device acts, also the power reserve will be less. Hope this is clear now... Yes, but again - not the pendulum, but the anchour.   About the loosing time... In this kind of escapement, the frequency pritty much depends on the torque. The higher torque - the highrer frequency. This is because this escapement forces the pendulum to oscillate significantly faster than it's own resonant fequency. The frequency depends on the 'depth' of the escapement too - the deeper escapement is, the lower the frequency, and the higher amplitude of pendulum oscillations. The heavier the pendulum is, the harder to the movement (the escapement torque) to force the pendulum to oscillate faster than it's own frequency. And in the end, the own pendulum frequency depends only on the pendulum lenght and a little on the suspension spring 'strenght' This are all the relations between all the factors. You can try to use the old spring (if it is not broken) and see if the clock will work faster with it. Yes, the old springs of fusee clocks sometimes give bigger torque than modern ones, no matter if they seem to be 'set' You can shorten the pendulum to achieve correct frequency. If the torque is reduced, but enough for the movement to work reliably,  then reduced torque will only lead to lessen the wear. The torque in fusee movements is more or less constant all the time, this is the function of the fusee. You can use the Clock Tuner  free app for android to adjust faster the clock rate. You will need to know the BPH of the movement, so count the teeth of the wheels and pinions and calculate the BPH
    • Hi! My bad. I meant to say that when the pallet fork is installed I cant move the wheels "using the crown in the setting position" Really in truly my number 3 was redundant and badly written (trying to explain myself went all wrong). I dismantling partially the watch (calendar, remontoir, Balance and Pallet fork). I think I would need to go that way...  Thanks for your comments...    
    • this is what happens if you don't fully do all of your research. I found the safe answer I found your exact caliber we got a mainspring number we got a price at a decent price for the original spring verified that the spring number at least on bestfit agrees with what we have so it was safe yes I did look in the GR catalog I had seen that 200 watch has a spring similar to what you perceive it should be. But to be honest I never looked at the 200 watch to see what its mainspring was. then the other amusement I went back to the bestfit online because if the 200 have the same spring I were to see that when I snipped out the image up above. Turns out they don't even show a 200 listing at all.
