I'm working on an International Time Recorder movement for the first time ever. Those mainsprings are . . . formidable. Is my Ollie Baker spring winder going to be able to handle those monster springs?? They're making me nervous.
Nope. This is the movement from an International Time Recording time stamp clock. I've found that I don't have a chuck large enough to use on my Ollie Baker to deal with these springs. So I'm working on Plan B. More pictures to come.Are we talking about the chime mainspring on a Sonora? Yes, the Ollie can handle it. And, yes, it is scary nonetheless.
It is the double barrel time only movement. The #10 has been used for ships clocks but also for many other applications like time recorders and scientific instruments.I thought that the #10 was the double barrel time only movement for a ships clock. Guess not!
