Yes, this is what I do on Sundays. Climbing up remnants of wood that have been shaped to look like a machine. Making sure all the loose bits are hammered into place, the axis is lubed with pig's belly fat and looking out for wood worm activity.
And that's just the first half hour.
And yes, that is part of my leg about 3 meters off the floor and 12 meters off ground level. Not bad for an acrophobic I might add.
