Take a piece of wood or a line or anything which represents a straight length. Say you want to divide it into five equal lengths. You guestimate what looks like a fifth of the length and open up the dividers by that amount. You then "step" the points along the line. If you've fallen short, you open up the dividers by a guessed fifth of the amount of the shortfall and close by a guessed fifth in the event of an overshoot. Repeat the foregoing. Once you've made a couple of adjustments, you are usually bang on. Then you can press the points in a bit to mark the wood.Well thanks Andy Kev, I know how to divide up easily by laying a ruler across at an angle but never used dividers for the same thing and can’t quite picture it, would you care to enlighten me/us please?

Despite being born well into the metric era I will often think in imperial to size something up when sketching a rough design: i.e. "that hand rail should be about 3' 9" from the floor" but will convert to metric and round non-critical dimensions to the nearest convenient standard size when I actually do the detailed design drawings and prior to working out any fine details.Also, why the hell does a 25 year old, say, want inches on his tape measure?
