    The radius of the circle divides the circle into 6 even parts.. I was playing with my divider once and totally by accident discovered that.. I'm sure people a lot more clever than me have known this for centuries but I felt quite proud of my little own light bulb moment..

    Hi Ade, You don't need to do any of the tweeking, if you scribe the radius of the circle from the centre with the dividers and then chose your starting point, without adjusting the dividers they will step around the circumference exactly 6 times. Its a well known geometrical construction. If you want just 3 points then use each alternate mark.

    @CleaveMountaineering 4 роки тому +2

    great trick, I didn't know that one. for a 6 hole or a 3 hole, you can also set your circle radius, scribe the radius. The edges of the hexagon are the same as the radius. So just walk that around the circle. If you only want 3 holes, just drill the 3 you want. But this trick works for any number of holes I suppose~!

      Hi John and thanks for the comment on my video, I have a DRO on my mill but it is cheap and I find it unreliable, so I rely on the old fashioned ways to work things to my needs, and at least this way I can guarantee the precision. Kindest Regards. Ade.

      Or just use this formula: sin(DEG/2)*2, where DEG is 360/n, with n is the number of holes. Then multiple the result by your radius to give the chord length.
