Step 1: Planning and Drawing the Table Layout on a Paper (app. 30x60 Cm)
I planed and drew the table in Illustrator. The picture shows an early version of the table, (I know this drawing is differend. I don't have the file for the final table, so this picture will have to do) The scaling is based on the size of the steel balls I used. (from Geomag 12mm).
Once you have the table layout finalised, cut out the different pieces to make some templates.
Traw the templates on 18 mm plywood (so the table boundaries are higher than the ball. This is important, so the ball doesn't fly of the table to easy and if you want to make it to layered like I did!
