A rip at 60 degrees is called a bevel. He;s got the angle wrong, it will be 30 degrees on each piece for a total of 60 degrees at each intersection..... 360 divided by 6 (hexagon) is 60 per intersection.
This a a basic bevel cut using the fence on the table saw.
Ripping down the length of the workpiece is what would be required to make a tall hexagonal container.
Simple, unless I'm not understanding the original post.
You got me thinking now, I could be mistaken here but...
In Geometry class, (long ago!) I learned that each time you add a side to a polygon you add 180 degrees to the total.
A Triangle has three 60 degree corners, adding up to 180.
A square has four 90 degree corners, 360, and so on.
Following that rule, a 6 sided polygon should total 720.
720 divided by 6 is 120, so the miter angle should be half, 60.
A table saw is 90 when straight up, so 60 should work, 2/3rds of the way to the 45 they normally tilt.
When you picture a 6 sided tube, the intersections are obtuse angles, (more than 90) 120 degrees.
Love to know if this is correct, my shop here is in storage right now, cannot prove this to myself?
