Safety Pinions


Recommended Posts

Just found out how a safety pinion works when I released the mainspring and it still had power that I thought was dissipated. BOOM! The pocket watch blew up and the Center wheel, 2nd, was spinning. Thought I screwed it up as the smaller gear was riding high on the pinion and no longer seemed right. Turns out they are threaded in the opposite direction and this takes the force from the mainspring.b05bdb6769b455264bec6e85dd3c9e85.jpg8f478d0b367fe7269bd24b6244dc0080.jpg

    • Thank you for your introduction and welcome to this friendly forum. We all look forward to your contributions and continued involvement.  When it comes to tools buy the best you can afford a good set of watch makers screwdrivers if you look after them will last you a life time. I recommend Dumont tweezers Number 3 and number 5 for fine work, you can build up from there. You will need different strength eye glasses. Some now like to work using a microscope. Pliers the box jointed ones are best they don't go out of line.     
    • That we will, don’t really mind what the movement is, I’d like to find info on the maker, google is a little sparse and none of my reference books are coming up with anything 
    • Welcome to the forum, enjoy. Purchasing the best quality tools (if affordable) is the best option. However the skill of how to use them is even more important. 
    • My guess, a pin pallet, BFG? We'll see. 
    • @Randy55 welcome, here are some  screwdrivers I can highly recommend, not the cheapest out there, but I prefer them to my Bergeon ones.: And for tweezers I can't recommend highly enough the CousinsUK own brand titanium (link here), I even prefer them to the Dumont tweezers I have, here is my write up: Other piece of advice would be to 'cut to the chase' and get a trinocular microscope on a boom arm, I tried all kinds of loupes and visors etc, but now do 90% of my work on the scope.
