HELP?!?!

When I assembled my Eolo, I used locktite on the grub screws. Now I'm trying to change my tail gearbox to an aluminum one, but as I'm trying to loosen the grub screws on the gears and drive shaft, the screws are stripping out. I tried heating them with a soldering iron to loosen the locktite, but it's to no avail.
Any suggestions? I really don't want to have to replace my entire tail.

Try to heat and cold in water then heat it again many times, maybe it will work the loctite.

Try using a heat gun to heat the area, not just the scrub screw. You need to loosen up all the loctite and not just the little bit on the scrub screw.

You might try putting a dab of fast setting CA on the tip of your allen wrench then inserting it into the bad or stripped head of the screw. This might make it tight enough to get it out. You could also try and american type allen wrench since the metric are just a tad bit smaller, the american sizes are a tab bit larger. I did the latter on one of my stripped screws and got it out.

You can also put a dab of valve grinding compound on the tip of the allen wrench and try it.The grit in the compound will take up space making the fit tighter plus it will "Bite" the wrench and the screw..

This will generally work...

thanks for all the tips, I'll be trying them out later when I've got a few minutes. I can attest to how well that locktite works though!

If your grub screw has stripped use a 1/16" hex wrench. Its a snug fit so you will have to work it in a little but it works great. I bought a nice 1/16" hex wrench just for the Eolo's grub screws.

Check your allen wrench. When mine started to slip, I noticed that the allen wrench was starting to "round" off on the edges. I just grinded them down a little with my dremel untils I get fresh edges and they work much better.

you can also take an english wrench and file down the tip (hex-taper) just a bit to make it easier to get into the rounded grub screw.

I have noticed a great variation in grub screw slot tolerances. I am going to order a bag of good quality screws from microfasteners.com (hopefully they will be good). Whenever I put one of these screws in, I check to see how loose it is on the wrench, if at all loose it goes in the trash.

The other thing you can do is use a longer grub screw if it does not interfere with anything, since it has a longer hole.

keepin' it real
