40 foot monopole tower

The fifty foot monopole tower I posted a few months ago requires five twenty foot (6 metre) poles. I wanted my troop to build 4 monopole, but we didn't have enough long poles. This slightly shorter version only requires three long poles, so should be in easier reach of troops with small pole racks.

 A few things to consider for this tower (and any other tower, really):
  • shear lashings, of the German, Dutch or 'English' variety, should be used in pairs spaced a few feet (literally: I tell my Scouts to use two shoe-lengths of the tallest Scout in their patrol) apart. The lashings are indicated as grey lines in the drawing.
  • If your poles have a noticeable taper, the heavier eand should be on the bottom of the tower
  • This tower benefits from a small post hole being dug for it, so that it heels in to the hole when it is raised up.
