Thanks gents..!!
Still preparing and collecting data for the build.
Working on a "handmade example" of the ribs.
Emphasis on handmade, virtually impossible to make 70 ribs ( including spare ) in this scale and make it look good.
Been working with adobe illustrator, and the lot is now with a laser cutting company, will have the first test tomorrow.
Supposed to be much neater then the handmade. ( though still working on it )
