I use JBWeld, it will never slip again.

Not much room for error on that thread. Delicate job, well done. The American approach works well too!

DeQ, not to take anything away from your awesome shots and the super detail and instructions you provide for which we are all grateful, though this post reminds me of the "zero-gravity" pen that NASA developed at a huge expense for the space program in our race to the moon. I think it cost something like $250,000. then..... The Russians used a pencil

Please keep posting, just had to share that

Excellent! I learn something new every day. I've used heli-coils (what we call them) a number of times but never thought to use the drill by hand. I've always used an electric drill. Which is extremely high risk when fixing spark plug holes in that the chips have a high likelyhood of falling into the cylinder. Not so much doing it by hand and using a vacuum hose

Thanks!

I use a drill press to hold the drill and then the tap to make sure that it is perpendicular to the part.
