Drilling thin sheet with large drill bit
Just watched this clip on drilling thin sheet metal with large drill bit. i had heard of the method before (maybe on here) but it looked useful.

David. Drilling through a rag. I know that, good thing. A method that is not taught and young people do not know it.

Some of us old guys don't either.

THANKS.......... that is admittedly a new one for me . I would much rather punch holes in sheet metal but sometimes don't have the correct size tooling. Now something new to try . ~ John Buchtenkirch

A great reminder of a trick that I have used for over 30 years
it works great on large drills as well 1-1/2" to 2", in 16 Gauge and 10 Gauge Old shirts and jeans cut up into 3" squares. Just go real slow on big drills. Just be safe Even though I have done this plenty of times, nobody should try this if they are not comfortable with their ability to use a drilling machine correctly. Just remember to clamp your job down so nothing moves

No way in hell would I be trying that, it’s a hole saw or step drill for me. Both are much safer ways than having bits of rag that can snatch the workpiece away before you’ve got time to react. Clever concept but certainly not a safe way of working. There’s a reason why that’s not taught

Of course, this is an emergency method. You must not use your own sleeve ....

Sandwiching the metal between two pieces of wood works well.
Parts can be centred by drilling a 1/8" pilot drill in the top piece of wood and the work and then using a 1/8" welding rod in the chuck. The work and timber must be securely clamped.

Watching that video was timed perfect! I went out to the shop and had to drill some 1/2 inch holes in some .025" material,... that method really does work! Wish I knew that method years ago.
