video Perfect Circle Tabletop from regular 2x4s using a table saw
This is an update to a video I did 6 years ago. This $150 has been used to cut thousands of circles and maybe 10 blade replacements in 5 years. ORIGINAL VIDEO IS HERE:

I'm starting to feeling like I've been punked. The more I think about it, it seems impossible for that straight blade to make such a tight curve like that. I believe you, I think, but ... this isn't April fools is it?

Real, the progressive raising of the blade creates a curved bevel on the outer cutaway piece. The inner stays smooth. It would not work as a one shot cut so the raising makes it possible.
Then you should try making a round wooden bowl with a table saw:

or a sphere with a circular saw:

Thank you for the nice comment. Hard to believe the other video was made almost 6 years ago.
