Not sure who this guy is but what did he stick in a vice

Man it’s crazy to see the difference in your channel from then to now. We’re so proud of you; you’re all grown up now.

This technique has been kept quiet for too long. I'm glad somebody finally broached the subject.

Such a well mannered and refined gentleman. I look forward to seeing more.

When I was 18, in 1978, I got a job at a small 30 person manufacturing plant, (there used to be a lot of those), one day a month I needed to broach a couple hundred parts, we used an arbor press with about a 2 ft. long handle on it.

Holy shit he's talking like a normal person!

I like the broaching. I used to not own a shop press. I was able to straighten out the acme thread on my big, heavy 6" vise after using it for a press. Now I own a press.

"Summer Teeth". I love this guy because he's always teaching me the fandango slango.

If anyone of you out there have actually done broaching, you would realize that this is a nice demo of what you can accomplish if you have to.

You're the Bob Ross of metalworking.

Try rounding out the bottom of the broach to fit your starting hole diameter. Then cut your relief cuts. The broach will start round, as does the hole, then works itself into a square. No file work that way. You would have to make the broach longer with a longer tapper, but it works. Just sharing...nice work here, well done.
