Hello everyone.  I bought an old Colonial Grandmother clock which i was told runs but i cannot get it to do so.  I think a piece connecting the pendulum to the clock came loose while driving and i have no idea where to attach it to.  Thank you for any help.  20200705_152447.thumb.jpg.03b3b1d5ff2a10df91916e7060b29f1f.jpg

The bit that has come adrift is the  escapement anchor, some of these fit onto a shaft and are retained with a spring wire with a flat end  . The Anchor operates on the escapement wheel locking and unlocking the wheel.  Look for the shaft on the plate   where the anchor is located.  Easy way will be to find the spring retainer and rotate it, it will lead you to the shaft.

Ok. So my next problem is that the right side weight will fall as soon as it is attached while the left side weight refuses to budge except for pulling it up. The prior owner lubricated the gears with WD40 instead of the proper oil.

The right side weight is for the time and the reason its falling is the verge (the part you said fell off and you have pictured) is not attached.  The verge meshes with the escapewheel to cause that tick tock sound and regulate the motion works to keep time

Hi  The right weight is as  explained and drives the time side gear train the left is the strike side and only releases either on the quarters or on the hour depending on type of clock. fit the minute hand and move it round the dial to determine the strike pattern stopping at the quarters and watching the front plate mechanism for the release. This movement will probably have a count wheel with the slots in governed by a set of levers/wires as per the attachment.

      Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!

      Gamblin Gamsol for cleaning?

      By joelcarvajal · Posted

      Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?

      Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.

      Movement inserted from crytal side

      By Zedster · Posted

      Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?

      Main spring

      Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
