Contact haydn.huntley@gmail.com for MagBalls, magnets, and extremely carefully assembled, precisely measured carbon fiber arms.
I test and measure each set of arms. The magnets in the joints have a tested holding strength on a MagBall of at least 1.5kg. The arms in a set match lengths within 50µ, according to my calipers, and typically they match within 30µ.
All sets of arms include MagBalls, N52 magnets and CNC’d Delrin ends.
Lubricant: I use bicycle chain lube. Stays in place, sheds dirt. My favorite is White Lightning Easy Lube
