sessions westminster pendulum length

Recommended Posts

I am working on a Sessions Westminster that I believe is a 416 W.C. or a Westminster chime C.  The clock was missing the pendulum and weight so I am wondering if anyone could help with pendulum length. Any input would be greatly appreciated.

This is a two train Westminster chime ? the pendulum rod will hang to the very bottom of the movement plates which places the pendulum bob just below the movement , the suspension spring and rod would be 5 1/8 inches.

Photos would help.

I have two, two train Westminster clocks one German which I believe to be made by Peerless (Mathias Bauerle) for which I was able to find with help on another forum the original patent information  and a English Gillett and Johnstone, both these clocks use remarkably similar differential gears for controlling chime and strike on the hour, whilst doing research on those I found the Sessions clock information , I do not envy mrxmttr his work on this clock, all information states they are a absolute nightmare to work on :pulling-hair-out:

Thanks you all for the help. And yes this clock is a little more difficult than many others but it is reassembled and running. just not keeping accurate time yet. I hope to make that happen with the help provided by this forum. Thanks again.

    • Update I discovered the setting lever when crown is pulled all the way out does not engage because (see picture below) the post on my timing lever is gone so the lever was not secured at axis point which limited the range in which the lever could full extend. I ordered a new one should be here in a week. I will keep you updated, what I think happened is someone pushed the setting lever post to allow stem to insert or remove and they pushed it to hard and broke it.
    • There is a Jasco made Naphta sold in hw home improvement stores in the US. It's described as being the thinner for varnish and enamel. It also says that it cleans greasy, waxy, oily surfaces and machine parts. Would this be safe to use on watch parts including balance complete?
    • Hello everyone, My name is John but you can call me Jack. I am new the group here and have been a hobbyist repairer for the past 2 + years. I mainly stick with mechanical watches but from time to time I will tinker with old quartz Seiko watches which I love. A current project that I have been trying to get down is a Seiko 4336 8129. This watch has been fighting me from the start. Well the movement was dead due to a broken pivot on the motor. So I sourced a replacement movement. Next Crystal was cracked so I removed the broken glass but can't figure out how to take the top bezel ring off. I have some pics. This poor watch has had a rough life. I was trying to bring it back!! Thank you for reading my tale of woe!!  
    • I am looking for a camera with a macro function to photograph my work.  I had a 18 or 20 megapixel Sony point and shoot that worked great for super close pics, but lost it in a fire.  Dont remember the model but it was a pocket sized camera I could zoom and focus on pallet stones with excellent definition.   It was less than $200 US.   Now I can’t find a camera that will do the job for less than $500  Any suggestions?
    • Can you repair my Timex Rally also?
