Jiggity jig

It’s been quite a day, waking up with our little Welsh valley deep deep under snow, then getting the Land Rover stuck and returning without reaching the outside world. We do have enough rice and lentils to last until spring, so won’t starve.

Back to the story…..

Using this picture from Google Sketchup, we saw that the diameter of the ‘silo’ was half the zome radius. (Here the zome is  the whole shape made from the extended Flower of Life and the actual structure is obviously half of this shape.)

One bright morning in the oh-so-wet-when-we-were-there Harz Mountains, Germany, the Scholar and the Heart woke up and decided that they have been looking at 3d modelling programs for too long, and it is indeed time to do something about the jig. Of course, being nincompoops, they did not come up with a plan of action, but just decided to go to the recycling yard instead.

So they jumped into the 1820 4×4 truck and, after a few morning chores, were in Germany’s finest recycling yard. Yellow vests sourced, they stand in the middle of the yard still plan-less, realising that the truth of the matter is that there are not two bits of metal here which are the same, so actually making a generic former, requiring many identical sections of metal, is a long way from being achieved.

The boys wandered around admiring the junk, the big mixers dreaming up legendary machinery until noon, when all the big machines, trucks and burning male energy was getting some what burning, when a tractor and trailer came and offloaded their content on the ground. Mr Heart decided that whatever the contents of it are, they must be able to construct a jig, or else those mountains of steel will never yield a crop, because as mountainous as they are there was simply no way to get anything out of them.

The contents of that trailer load did prove to be promising with T-profile lengths of mild steel: the perfect (better even than square section) clamps. With another little forage in one of the scarier less piles of steel, they found a box section 50mm x 50mm already curved to shape!!!  It was over bent, but, with some crane persuasion, was made to the perfect diameter.

They also dug up the contents of an interesting barrel, that proved to contain a horde of heads of various axes and adzes, one of which seems to be  medieval (ended up as a present for our German host, Boris, as a gift of appreciation).

It is quite a sticky job lining up the 3 layers of wood, getting the nuts on and tightened as the fast drying glue dries, but latex gloves do help.
