Broken ratchet wheel screw

[FST]

Hi Marc. Love your channel. I watch it every day. 
Based on your videos I Started evening school watchmaking. Second year now. 
I ran into several problems of course. 
the last one is from a women’s cocktail watch. The ratchet wheel screw is broken and is in the barrel arbor. Is there a way of getting it out?

thanks for sharing your experience

Hello and welcome to the forum Frank,  Regarding your problem. Unfortunatly the only way will be via drilling it out or the use of a screw extractor as probably some one has either overtightened the screw or if its a LH thread gone the wrong way.  As both are made of steel the use of the likes of Alum (which eats steel) is not possible. The other recourse is a new arbour and screw.    all the best.

Before more radical measures try turning it with driver in both directions. It could have a left thread and got snapped by someone turning that way right to remove it.
