Hello, all. This is my first post.
I've been enjoying the various 'Clock and Watch Porn' videos on Youtube for a few months and, as is my wont, thinking, "I'd like to try that."
Finally, I found an old wall clock going cheap which seemed suitable for some novice tinkering. It was missing a minute hand but everything else was there and the case looked good. Having got it home I was able to give it a wind and get it ticking and on turning the cannon pinion, it started striking the hour. When it got to 14, however, even a rank beginner like me could tell all was not entirely well so I started investigating.
The movement was covered in old, sticky oil. It looked like it might have been dipped in the stuff. On the back I found a maker's logo with the name 'Gustav Becker' and a quick Google produced enough info to suggest I may have picked up a bargain. There was also a Serial No - 2130951 which I think dates the movement to 1925-1926.
I've dismantled the movement and started cleaning it. It looks structurally sound. Fortunately, I won't have to start learning how to re-bush the spindle holes just yet. The main problem might be the mainsprings. The one on the time side was absolutely caked in green, sticky gunk. I managed to manhandle it out of the barrel enough to clean it but the outer end wouldn't unhook. It looks like the original hook has been replaced with an old screw head which has been passed through a 'washer' to stop it slipping through the hole in the spring then hammered flat(ish) on the outside of the barrel. The strike side mainspring was reasonably clean but it appears to have broken and been repaired. The two ends hadn't been lined up very well and a raised corner was digging a groove in the barrel cap. The coils are also very uneven so I didn't bother trying to get it out. Both springs also look to be a little short; they occupy very little of the space inside.
Any comments or advice would be appreciated.
