One of the things that camera restorers (and other people who repair small metal mechanical items) encounters is jammed or broken screws.
For those dealing with larger screws/bolts it can be easily dealt with by using left handed drill bits, or specialized screw extractors. For us dealing with such small metal screws, it becomes more of a challenge. How to deal with a <1mm screw? There is not much material to deal with and there are not many tools for this size job.
I recently acquired a camera in very poor condition. It obviously has been stored in a nasty environment as it was coated in crap and signs of corrosion … one screw had the head broken off, I broke off another screw head while attempting to remove it, and there are a couple of screws that just won’t budge (I stopped before stripping the slotted head).
So … what to do? Get more tools. I am thinking of attacking it in a number of ways:
- Drill out the broken headed screws … need to get a drill press for my Dremel.
- Use a precision screw extractor … Moody Tools has a tool set for this.
- Solder a lever to the heads of the stuck screws.
I will follow up after I attempt any of these … if anyone has another suggestion I would be happy to hear it.
