Rollation technique

Famous sheet metal fabricator Ron Covell explains and demonstrates the rollation technique in a youtube video. Not paper, however, very useful for those unfamiliar with rollation.

Very interesting video. Ingenious simple methodology. Although targeted at metal workers, I can quite see the usefulness in adapting the methods to paper designs. Especially in forming aircraft fuselages.

Very useful. I like doing things without the computer.
