Fastest Way to Center Work in a 4-Jaw Chuck

While revisiting some of my previous posts, I stumbled upon David's video which I realized can greatly benefit beginners due to its usefulness, hence, I decided to re-share it for better visibility. This post initially surfaced in February 2010, however, to avoid triggering Google's policy against duplicate content, I have removed the original post. Here is the complete post:

Got a nice note from David Lemereis this morning directing me to some YouTube videos of some of his latest projects. He's built a powered drawbar he says was inspired by mine that has some great improvements as well as some other mods for his BF-series mill (I can't tell the different sizes apart, but it is a really nice looking mill). By all means, go check out his videos as they show some very nice work. But, what really caught my eye here was his video of how to center a 4-jaw very quickly:

This is the method I've been using since I first learned about it from Jack Burns on the HSM boards. I really do think it is the fastest way, and it has worked like a charm for me ever since I discovered it. Now David makes it look even easier with his video. Newcomers need not be afraid of the 4-jaw once you've watched the video!
