Anybody fancy plank for dinner?


Recommended Posts

It can be fixed using the original holding arms. As a prototype it’s very much a work in progress. If my mate approves the concept then we will work on the fixes. The work will be improved (not my Heath Robinson approach:) ) and my choice would be to have a number of colour options available using different veneers and leathers

I thought this was a one off, if you are doing it as a selling item maybe try a few of these things.

To get the curve, use 3mm ply cut 3 pieces to size, make a jig, a bit like a bricky uses to get a curve on an arch opening, however have a male and female, glue with PVA the 3 pieces together and clamp it, when dry they will hold the shape.

To tidy up the top, take the front  level with the curve and hinge with a piano hinge and use a magnetic clip at the bottom , that way you have a door to access the movement. This will let you add a bottom to the case, a few strechers across the top and it will be strong.

I am not saying the way you did it is wrong, just trying to help in the ongoing project.

Thanks Jimmy, I do appreciate the advice. The way I’ve done it wouldn’t be the best way and needs improvement. I’ve done this one purely as a prototype to show the design to see if my mate would like it. He has a stock of twenty or so movements and wants a unique design to put them in. This was my idea for him and also a little project to house the little French movement. If he goes for it then we would work on the design to get it right fixing the problems and sorting out the best manufacture process. I’m pleased with the look and blend of materials and personally think it is quite smart, modern looking with a nod to the old.

    • I will advice to share the idea first here before doeing something to the movement
    • When you move the index which changes the timing from an extreme fast to an extreme slow, is there a big change in beat error? Obviously there will be a big change in timing. If there is a big difference in BE then this is strongly inferring the the end-curve of the hairspring isn't set correctly or/and the collet is central to the jewel on the balance cock, because the hairspring that is breathing between the curb pin and boot is being pushed and/or pulled when you move the index from left to right. Also not having the hairspring set correctly can dramatically reduce the amplitude. A quick check is to take power off the movement and move the index from extreme fast to slow and with high magnification see if the hairspring sits nicely between the curb pin and boot at all times (give the balance a spin and watch the hairspring - has it got total freedom?) or if it moves by being pushed or pulled by the curb pin or boot. I'm guessing it is the latter. I think that may be a possibility to your problem.
    • I can't get windingstens.com to open but you need a  few measurements. 
    • All Done, Here are the finished pictures: This one shows the generic "one-size-fits-all" base which accepts the bespoke rings - notice that the parametric movement OD (27.40 mm) automatically prints on the ring 🙂 From another angle: Here is the ring about to go into the base: And finally the base and ring together: Here it is next to a pen for scale: On my system with 20% fill each ring will take about 18 mins to print, but I am sure this could be optimised: Here is the screenshot of the spreadsheet in FreeCAD, you just need to change one value to create the ring in cell C3, (the base doesn't need any changes). I just uploaded the files to printables link here, but also include  here as a fake pdf, please change the .pdf to .zip to make the file work once downloaded: Modular Movement Holder.pdf Any feedback welcome!     I'm also going to make a parametric ring insert for rectangular/oval movements - but I just finished a parent teacher evening so too tired now 🙂  
    • I'm going to give that a go next time, thanks for a great idea @rossjackson01 One of my students uses this tool and swears by it https://www.cousinsuk.com/product/wheel-hand-roller-remover-bergeon?code=W1851 which is very like getting two sticks of pegwood under the wheel and rolling them in your fingers so they create a slight prying from underneath motion, I suppose. Maybe bind one end of the two sticks of pegwood so they are like tweezers.
