Jauch Arbor

[oldschool]

Good Morning All
I am New (Newbe)to the repair of clocks. I have been collecting for a few years and been sending them out for repair. Its my turn to take up the servicing and saving some cash. Well let me cut to the chase. I picked up a clock with a Jauch pl61 cm movement the last owner had broken clean off the mainspring key section of the arbor. I search the supply house’s and due to the age of the movement could not find one. They all told me to try to find a movement on e-bay that I could use for parts. I did and no one had one for sale. I was wandering if any one out there could hook me up? Is this movement a good one because nobody wants to give them up on E-bay?
Thanks 🙄

Hi oldschool,
do you mean the part of the barrel arbor that the key fits on to to wind it? If this is the case you would do well to make sure they have not done further damage to the mechanism by using such force? If you know someone who owns a lthe it is not too difficult to make a new arbor.
If you mean the tang that is used to hold on the mainspring, that can be replaced.
Let us know which it is and we can then help further

Hi Arutha
Yes; it is whare the key attaches. I removed the barrel and i will need to place a bushing in it. I have an issue machining it due to the square end at the click gear. It may be out of my expertise. But if I cannot fine one then I could do no worse right!! ha ha. Is it stainless or just steel that they are made of. I want to thank you for your help.

It is just steel, the square part at the end for the key is quite easy. Just put 90 degree marks on the lathe chuck and then file your flats. It may take a little practice to get it right but take your time and do this first before then turning down the diameters for the barrel etc. the harder part is the tang that the mainspring clips over. This can be done by inserting a suitably sized steel screw into the arbour and then filing to shape.
Good luck
Paul.

Old School,
If you have access to a drill press and do not have a lathe, you can put the arbor into the drill press chuck and use the jaws of the drill press vice as a file guide. You will be filing it vertically insead of horizontally as you would on a lathe but you still should get an acceptable result. You can mark off the 90 degree positions with some masking tape wrapped around the drill chuck and the vice jaws can provide sufficient locking force to hold the part while you are filing it.
