Hairspring Vibrating Tool.


Seth

Recommended Posts

Hi there, Can anyone help me with any information on how the lever to set the balance wheel in motion on a hairspring vibrating tool works?? I have obtained a vintage tool and on the end of the lever is a small shaped piece of spring which doesn't seem to do anything when the lever is moved.I presume that this should somehow set the balance in motion but at present it does not.I enclose a couple of photos of the tool.Many thanks,Regards, Seth.

Hi there , Place the tool down in front of you so that the pointed main body part is facing you .Then the way you set in motion is to gently rock back and forth with your thumb and forefinger on the small pointed handle you see at the front . Once in motion the spring that you are talking about is used as a brake to stop the balance wheel .just move the little lever  , you will see the balance stop . If the balance wheel does not move then you may need to check pivots and that hairspring . hope this helps .

    • I'm sure you will get help on here soon.  Kkramme we like new members to make an introduction before posting. A little about your self such as where you life and what got you interested in Horology  
    • I'd be grateful for recommendations of good sources of advice on getting clocks with balance spring - as opposed to pendulum - escapements 'in beat'.....
    • Well I am in a bit of a quandary. I can't find the correct colour for the dial. I even wrote to Hettich a while back hoping they would give me the colour code for the dial. The reply that I received was "We don't make those anymore." I am thinking now to silver the dial and use a water transfer decal to put minute markers and the HETTICH logo (which is the very font that this forum uses) and the Made in Germany down the bottom. Not sure of the success rate of the water transfer method, but I have no other solution for the markers and logo. Handpainting is just not an option. In trying to get the top piece of the clock polished, it has progressively lost its sharp edges. My stupid hamfisted effort. I am thinking of purchasing a replacement piece of brass and drilling new holes in it for the corner posts. Why I attempted to repolish using wet & dry and not simply using a paint remover to remove the old lacquer from the brass, I don't know. You whistle and I'll point at the idiot. I also need to purchase some sheet spring steel as the two small ratchet springs that arrest the wheel that supports the weight after it is lifted by the electromagnet are worn. The two from the donor clock that I purchased are worse. I am hoping that I will be able to manufacture new springs without having to fiddle about with tempering etc to the steel. I have some ideas on that front. How many things until the clock is no longer the original? Like an axe. Heard a woodchopper on tv once saying that he had replaced the head on his axe twice and the handle three times, but it was the same axe that he began woodchopping with. 😉 I must post more often or read back through what I have previously written. Keep repeating myself. Sigh.
    • I use the exact OD and it fits in with a little force and a pleasing 'click' so it's snug and wont rotate within the holder, but that depends on how you have set up and calibrated your printer so you may need to play with the settings/dimensions a little to allow for any discrepancies in your printer calibration. PS I just finished (2 days ago) a new revision which automatically prints the movement OD on the bottom of the holder, I'll see if I can upload it here Here is rev 4 remember to change the .pdf to .FCStd so it will open in FreeCAD - also you may need to install the LiberationSansBold font and tell FreeCAD where it lives on your PC, or change the font to something you already have on your system.
