Steadycam for reflex

I built this tool by recycling many things like the ball bearings, the handle and the metal rods. I used two 1,5 mm ball bearing (from a CD/DVD player rail), a 5,5 mm bearing (from HDD) and a SW Z809 ball bearing (8 mm). I designed also the two-axis rails (a sort of macro-rails) to adjust, in a simple way, te weight distribution. I took the horizontal rod (at the bottom) from Meccano and I used two tennis balls to calibrate the cam stability.
