24.09.2021 Base ring arcs.

 *

Friday 24th 60F, bright and breezy start soon became heavy overcast. Yesterday's storm went unnoticed in the shelter of our garden and trees. Though it did pour down a few times. A few twigs were ripped off the tallest willow.

I have cut out the last eight, dome, base ring arcs from 12mm Baltic Birch plywood. 16x1.5=~24m. That is a long cut with a jigsaw. 

Next I shall trim them with the router against a pattern. The arcs were cut out very close to the scribed lines. So there shouldn't be much material to remove.

I had to dash out and tidy up during lunch because of rain! Grr!

It was still raining lightly later. As I trim routed then orbital sanded the last of the arcs. Enough to complete the base ring in three layers for 36mm overall thickness. The birch plywood is very prone to dark staining when left out in damp surroundings. Even when covered by a tarpaulin. Presumably a form of mould.
