This protractor angle gauge will easily allow you to set any angle when launching your compressed air rockets.
James Montagna, one of our customers who is a STEM Teacher in Farmington, CT. James had sent us pictures and files of a laser cut protractor he had made for his launcher to use with his students.
This angle gauge will accurately identify the angle at which the launch tube is set. Ideal for teaching ballistic trajectory and for use with physics competitions.
We offer an educators discount on our launchers, just ask!
Print one gauge (light color), one compound wedge (any color) and one pointer (dark color) for best contrast. Use ultra fine point sharpie to make gauge numbers and degree marks more visible.
Refer to video for installation. Use large flat blade screw driver to drive wedge into place to clamp the protractor to the wooden stand. It should only fit one way due to the double angled faces.
