      Good (insert time here) everyone!
           I am relatively new to the world of clockwork repair and maintenence, but have done delicate metalwork, mechanism cleaning, and enjoy fixing things. Just recently, my sister brought home her boyfriends late great grandmothers singing bird in cage automata. For those of you who dont completely know or understand what it is, its basically a spring driven mechanism using bellows and a variable organ pipe to make bird sounds and move a little birdie around and "sing" (Example of singing bird mechanism working).
           His aunt wants it to be operational again, and after opening it up (not yet taking much apart) I have come to the conclusion that it could just use a good cleaning and oiling. But, my question is, what kind of oil should I use and how should I apply it? I don't have any fancy oils except for a bottle of valve oil for my trumpet at my current disposal, but I would like to buy some decent clockwork oil for this project and a sankyo music box repair I have waiting. 
       
           Note: come to find out while writing this, it was made by eschle reuge I'm Germany, probably around the 50's or 40's.

      When I look at watchmaker workbenches i see that it is performed in many different shapes and designs. I would like to see and hear about your experience with watchmaking Workbenches. What to prefer in and what will you recommend. Image of your own solutions will be great. It is specifically the top plate I am thinking about!
      Thank you in advance ...

    • Well fiddle sticks!!!! I have corrected one problem but created another. I figured out that I didnt have the hammer mounted correctly. I fixed that and things seemed to function a bit better at least between depressing the buttons. I got a little confident and figured the crazy reading I was getting on the time graph was due to a bunk balance. So I decided to look into it. I have two assemblies. After a closer look these too seem to be different. I noticed the hair springs didnt seem to have a nice concentric layout when put in place so I decided to try and tweak them. That was a mistake. So far the only thing that really makes me a bit nervous is when I start messing with the hairspring. If I can find a good balance assembly id rather just drop the coin on it rather than try to fix them. Ive included pics of them. I will order a complete balance assembly, if I can find one. I have a hunch that the grinding im feeling when turning the stem is due to a bad sliding gear so I am going to swap that out as well.

    • Ok so what is the difference between Rabuska's book and Terwillger's? Are the same thing or does one have pictures that the other doesn't? Thanks again!

    • It's my own homemade balance tack. Took a prescription pill bottle cap and some odds and ends lying around and voila. You can buy them too but there's something special when you make your own tools. You appreciate them more I find.

    • That is certainly an option. They should be available, and hopefully not eye wateringly expensive either, however it may be possible to fix the one you have. Just put on your safety specs and crack it open. I think a 2770 series barrel and mainspring would be correct, but check before you purchase. Something like this perhaps - https://www.ebay.co.uk/itm/ETA-Calibre-2770-Part-182-Complete-Barrel/222524899179?hash=item33cf847f6b:g:NLkAAOSw4CFYwvVt Also confirm with the supplier that it includes the spring.
    • I was more thinking about looking for a complete barrel to just replace it, not sure if I have the guts to open the barrel, would probably find the way to stick that spring into my eye.
