Hey Bill - they make a new tool now, oh, maybe 200 years ago or something. It's called a center punch. Nifty little thing, with a very sharp point of carbide steel or sumtin very hard. You can put that sharp little point right on a piece of steel, tap it with a hammer, and have a very precise divot right exactly where you want to start a drill bit.
Some of these "center punches" are even spring-loaded - just put the tip on the selected spot and push the tool downward. Makes a nifty pinprick right on the selected spot.
Any of you readers who has a law enforcement officer for a friend, give them a spring-loaded center punch. Fits easily in their pocket, and is just the ticket for opening a car window to allow access to a reluctant perpetrator who doesn't want to be friendly. Much easier than beating on the glass with your hand or baton. Carried one for years, even though I only had to use it twice.
As mentioned before, really enjoy your videos; keep them coming!
