a.noctilux Posted December 26, 2020 Share #2 Posted December 26, 2020 (edited) Welcome here, My suggestion ... Drill carefully a slot to unscrew with a screwdriver ? If not ... In difficult case you need adapted tools, like in this video to see how, go to 5:20 Edited December 26, 2020 by a.noctilux Link to post Share on other sites More sharing options...

jankap Posted December 26, 2020 Share #4 Posted December 26, 2020 (edited) There are left drills. I have bought one at Ebay to remove a dead screw of a lens. You must choose one, that is thinner than the inner diameter of 3/8" thread. Pay attention, that you will not reach the exact center of the broken screw. So still thinner than the inner diameter. If the drill alone does not help, there are special tools to remove the screw, they have a special left screw too (see the film of a.noctilux at 1:30). If you need further help, you can email me.

Maybe in the future you might use a little less strength. Link to post Share on other sites More sharing options...
boojum Posted December 27, 2020 Share #7 Posted December 27, 2020 (edited) Advertisement (gone after registration) If you use a screw extractor it is also a very good idea to first use some penetrating oil. https://backyardtoolshed.com/best-penetrating-oil/ This will save you from winding up with a bigger problem, a broken extractor. And remove that bottom plate before you work on it. If there is going to be damage, limit it. Bottom plates are way cheaper than cameras.

That will make it a lot more difficult. My bad. Just use some penetrating oil, a drop, give it an overnight to work its magic and then gingerly back out the bolt with an extractor of your choice. If you are at all squeamish, take it to a jeweler or a camera repair shop. In the future use a lens-mounted tripod support thread. My general impression is that the Leica M series is not a tripod camera. Correct me if I am wrong. Another case that is like chewing gum in church. You can do it but it is not a good idea.

My IIIf has the tripod thread at the far end of the bottom. Ridiculous, it should be underneath the center of the lens! I wonder, that the screw could be broken by hand. Perhaps the screw was too long and was at the bottom of the hole. I have mounted Arca Swiss adapters on my cameras. That adds weight, but it is very practical. Even the Tessina has got one! I also wonder, why Leica, Canon, Nikon, etc do not offer an Arca Swiss connection as standard on their cameras.

Parkplatzmann Posted December 28, 2020 Share #11 Posted December 28, 2020 if it is not too tight, you can try super glue to stick a little piece of metal on it and try to screw it out Link to post Share on other sites More sharing options...

AndreasG Posted December 28, 2020 Share #13 Posted December 28, 2020 If it was my camera, first I cover the camera as far as possible with protective tape and then I mill (or ask somebody who has a micro milling device) a small slot 1x3mm, depth 2mm into the remaining thread and remove the remaining thread with a screw driver.

I think yossishahak might have meant 'strap' - maybe one of those sling straps that attach to the bottom of the camera via a tripod screw? It may be tempting to overtighten those to make the strap 'secure', and the whole weight of the camera is on the screw... 1 Link to post Share on other sites More sharing options...

Torque at play - both ACW & CW, depending, and somewhat random - resulting in further binding, possibly. If the metals of the strap-anchor and the bush are the same or similar in the electro-chemical series, they will ‘weld’ if allowed, ie prolonged contact.

Use a dremel with a small cutting wheel to make a slot in the broken screw. Use a screw driver to unscrew the broken tap. Link to post Share on other sites More sharing options...

The idea is good, but the diameter of a standard Dremel cutting wheel is 24mm, which is too large, you would need a wheel with approx. 8mm diameter.

Anbaric Posted December 29, 2020 Share #19 Posted December 29, 2020 This isn't an answer to your problem, but if you don't also use tripods there are sling straps that attach to the strap lugs, e.g.: https://www.optechusa.com/utility-strap-sling.html Link to post Share on other sites More sharing options...

After a cutting wheel has been used a few times they wear down smaller. The key would be to use a used wheel or wear one down to the size needed. 1 Link to post Share on other sites More sharing options...
