Find a driver that will get a bite the set screw and heat the tip of the driver and use the set screw as a heat sink , a couple rounds of heating the tip and inserting it in the set screw will usually soften the locktite and let you back the set screw out .

If you're not living on the edge you're just taking up space !

Sears sells this miniature extractor set I've used with good results.
Take a soldering gun, not a wimpy soldering iron and put the tip directly on the grub screw to get it hot. That really makes the difference by softening the locktite. If you can't get the tip in there than heat up the end of something like a old steel rod and keep applying heat to the screw.

Remember, locktight is only needed in very small amounts. Next time, lightly use the Locktight. Don't drench it.

Are you sure you stipped the grub screw, or have you stripped the Allen wrench head. If you only have the one allen wrench, cut the wrench above the tip clean in half, and reinstall. Alot of the times those really small allen wrenches strip out, and it dosent take much at all.

If all else fails, use a solder gun, and apply what the above posts have said.

Grub screw
Heat the area where the grub lives then insert tool with a liberal amount of valve grinding compound. It often works! You can buy valve compound at most auto parts stores for next to nothing.

Sometimes JB welding the allen in the screw works too.

NEVER REUSE GRUB SCREWS!!!

- especially in larger pinions. They're dirt cheap. Save yourself some headaches and buy a few extra next time. Fresh alen tips are also a good idea.

Also when it's time to remove, heat them like I like I said earlier, put the wrench in and don't be a wussy. Give it a good twist.
