Default Old Cox .010

I have a pair of the old "original" Cox .010's that I got back in the 60's. One has the prop screw broken off. Is there a repair facility for these engines?

If you can poke at it with a scriber you may be able to tease it out enough to get a set of pliers onto the stub. Usually broken screws like this are not tight in the hole. I believe it's just a 2/56 screw to replace it.

Hmmm... A flowing gas co2 laser is simple and cheap. A hundred watts or so should do it. Definite possibities... It'd be easier than putting a carb on a reedie!

How about sticking it in a drill press. If you haven't tried that, it may work. (I've got one) Got your pm, I may call after work and see if your interested.

Seriously, though. They do make "easy-outs" and outher screw extractors that are small enough, but you would have to drill a hole through it first, which is kinda the hard part. The best thing to try would probably be a left hand drill bit. See if you can find like a 1/16" left hand drill bit, and start drilling it out with that (preferably secured in a drill press). If all goes well, you won't even have to dill all the way through, and the bit will grab and spin the screw right out counter-clockwise. Or someone could build you a laser. Good luck,

Ubird,

I would suggest you contact Tim Wiltse here on the forum and ask him. Tim handles all of my Cox engines and does a great job on them. I'm sure he can fix your ittybitty engine. He has a website but if you just do a search on Tim here in this forum I'm sure he will pop up.

good luck... I love my small ones...
