Sorry for the poor focus, it was my very first video :)
I made some errors in there and in some parts wasn't clear enough about what was being done and why. I'll do better as I gain more experience at videos :)

Rather than using tape around the drill bit to determine depth limit fasten on a depth stop collar.
