So, onward with making my globes and its time to make the front screens. However, in the absence of spinning perforated aluminum I am faced with drilling the hole pattern. The pattern is critical to get just right, so after laying out the dots in as close as possible to the proper interval I can see some of the pattern emerge. Now I get how to draw it out and in order to repeat it accurately I am making a simple fiberglass of 1/16th the globe overlay on which I will put the pattern and repeat it. I started with a spare globe shell on which to practice the layout. Lots of work ahead of me! But this should make it simpler.
