Here, here !!! Great gadgets, and usually a piece of cake.

I find it even easier than that. With Helicoils, if you've just stripped
out the female thread you can skip step one, because the hole is already
the correct size for taping with the special tap supplied in the kit.
The drill size is about equal to the major diameter of the finished
thread, and the hole is already at that size. If you have enough room to
get the special tap into position and are able to turn it with some magic
tool, you're almost there. But you still need room for the special
inserter tool. Bottom line is, it's real easy if you have about two
fists full of room directly in line with the stripped hole.
