Hi folks - Looking for a bit of assistance with the disassembly of this Lorch cross slide. Is it possible to remove the two plates shown in the attached photos? It looks like the plates should separate to allow me to clean out the old gunk and grime but I am unable to get them free. The pin protruding from one side is used to lock the plates into place at a specific angle but it only rotates about 45 degrees and doesn't appear to release in order for the plates to separate. 

Any help would be greatly appreciated.

Thanks

I think your variant is like mine, you need to rotate the excentre I marked in the picture until it feels loose, in the loosest position you could put a small screwdriver in the hole in the nobb and pull the excentre out.
After that you will be able to gently pry the two slides apart.

Tremendous. That's done the trick. Thank you very much for the speedy reply. It's long overdue a clean!

Perfect! Just in case someone else wounder what was going on I put some pics of the procedure here too.
 

When the excenter is loose pull gently and twist it a  bit

when putting the excenter back one should remember to position the hole correctly and gently tapp it back.

Hi Folks,

I recently obtand a Lorsh lathe with a similar cross slide.  I took it apart for cleaning and now I can't get it to go back together!

The two wind screws go back in for about 1" or so then the reistance is such that I don't want to turn them further in case I do permamnent damage.

Before I took it apart they ran smoothly.

Help!

    • Hi Joe, I mean the situation when the escapement can be unlocked when pallet fork is pressed as the guard pin to touch the guard roller. This will be possible if the guard pin is short or the depthing of the escapement is not deep enough. The pallet fork was replaced, but I don't think it was adjusted to work correctly with this movement.  Of course, if there is defect on the guard roller, it also can lead to such problem.
    • Hi everyone, I am new to watch repair and loving the whole process, even some of my fails…maybe. Right now I am looking at purchasing a press for fitting watch crystals, and I was wondering if any of you have had experience with the BMC model (seen in photo) and if you know whether the Robur press dies would fit, or, if not, what alternative dies might as I am having trouble sourcing original ones.   I know that the subject of crystal presses has been a well covered topic here, so I apologies for bringing it up again but I hadn’t found any past threads on this points. Any help on this would extremely helpful. Thanks! Joshua
    • Hi, I just wanted to share the unmistakable quality of a Rolex made in approx. 1990. Cleaned and serviced for a friend using appropriate oils and greases, with Epilame on the parts recommended by Rolex. New mainspring and upper setting and jewel for the minute Pinion (cracked jewel). Run in overnight and then worn on the wrist for a couple of hours to warm. Without any adjustment to the balance weights the watch ran at 0 SPD DU, all positions within +3 and -2. Vertical amplitude after 24 hours of 230 degrees minimum. Watch running at zero seconds per day on wrist when worn 24 hours. Serviced just once before 20 years ago. No need to buy the Microstella regulator tool, not this time anyway 🙂 No scratches or damage caused to screw heads and bridges. All seals replaced and waterproof tested to 60 metres. All good practice for when the time comes to service my own Grand Seiko.
    • My kid woke me up at 2:00 a.m. I couldn't get back to sleep so I decided to go to the workbench. I was to tired to work on a watch so I decided to dress up tweezers and screwdrivers while having a drink and listening to some music.     Luckily I got a comforting nap after lunch and started working on this beautiful Raketa Big Zero.  
    • Good shout - I'll grab something like that and some around the required size from cousins too...
