I now know how to make a circle a bagillion different ways, thank you.I gotta come back & rewatch this every time I start a new project.I'm impressed at the amount of circles this guy needs to make, and still hasn't purchased a compass.Do not do that first one. That is so freaking dangerous. those screws are very likely to wear down quickly, and go flying and bouncing around. Never mess around with grinders.That nut attached to that string that was attached to the wire and then you use the magnet to thread it through the plastic pipe is genius and it opens up a new world of thought for me. Thank you for this video and God bless you.
