Thread: Help needed in starting a clock

Finally i got it all working and now I can sit back and enjoy my work


Except that the pendulum wil not adjust properly why this is i have no idea but i believe it to be where the pendulum rods attatch to the upper brass piece as it looks as if it doesnt seat properly can someone post a picture of their lyre type pendulum showing how the rods attach through the bracket as i think this is the place i am going wrong and also i would like a little clarification, In the instructions it tells me to place the heavier weight on the right hand side but in all the diagrams it is on the left can someone please correct me on this


Cheers Guys

Pretty frustrating, hey. Sorry I can't help you with the fixing of the pendulum, but a dumb question, are you able to contact the supplier of the mechanism? Or send an email to the maker (in Germany I believe)? Just occasionally, you can really be pleasently surprised with the assistance they will provide.

Anyway, don't rush and I am sure you will get it sorted out in time and be able to really sit back to enjoy your artwork. Cheers

Hi Bob

I can't categorically answer your question about the pendulum because I have not built a grandfather clock. I have made several Regulators including large weight driven ones using Hermle movements and there is separate piece called a crutch lever or pendulum extension which attaches to the top fulcrum first. Do you have that on? You then attach the actual clock drive lever or anchor lever to that with a twisting motion in the centre slot as you join the two together. Easy when you know how! The actual pendulum hangs on to the bottom of all of the above. When the clock is working you have to set the beat by pushing the anchor lever against the resistance from one side or the other, until the beat is even. In your situation with a wide case you may even get away with giving the pendulum an extra good swing and let it set itself in beat. The Hermle movement will do this. You regulate the time by moving the weight bob up to quicken or down to slow the movement. You should be able to set it to within a minute per week.

Again I am not sure about Hermle triple weights however, the heavier weight is for the quarter hours. On my old Enfield grandfather clock that is the right weight when looking at the clock. I have a Keininger grandfather movement purchased in the UK in 1987 and which regretfully I have still done nothing with. The heavier weight on that is also on the right when facing the clock. Your clock will run regardless of where you hang the weights. It will just not keep time properly if the wrong weight is on. Try hanging the heaviest weight on the right facing you first and see how it goes.

If you can't sort it out call Clock Movement Importers (importers of Hermle) in Queensland on 07 3271 2555 and ask them.

Hope this helps. You have made two very nice clocks.

the pendulum is now fixed and adjusted so i only loose a few seconds in a fortnight so i am very happy it is always drawing comments at our house now with guests which is something i love to talk about.

Best thing i found out though as i did it as my Tafe project for my final year is that i got to claim it all even the mechanism as an education expense

so i had a little bonus

cheers

Congratulations and well done Bob!

just a quick update this is how she looks now all well adjusted

Bob
Is the pillow there so you can lie down and look at it.
I would, you have constructed a lovely time piece for ever, I been looking at doing one of them for a long time but as yet only talked about it.
A job very well done you should be proud, we all are.

the pillow is there as i forgot to clean up after my lovely little 4YO Daughter

but thanks for the comments

and i look at the burl in the base alot too
