Large Radial Dolly

Just finished building this dolly. Got the basic idea from Bob Hill's Cameraman's Multitool, but ended up using slightly different components - specifically the wheel assemblies with built-in laser mounts.

Wow, what a great job!

Excuse the noob question... what exactly is the purpose of the lasers? My guess is that they could help track speed against some kind of calibration grid, but I'm curious to know the real answer.
 
sinapps,

Someone asked about the purpose of the lasers. Basically, it is to set your radius by focusing two lasers on a fixed point (the subject), which should then remain centered once you begin your move?

The third laser arrived broken, so that's why you see only two. Yes, you point all three lasers at the same spot and the dolly will rotate around it. The lasers can tilt up and down so you can point them at the "chest" if orbiting around a person.

The benefit of 3 vs. 1 that moves from wheel to wheel is that setup takes almost no time and is more exact since you don' t have to remember the exact spot you pointed the last laser at.

I'll post a video as soon as the 3rd one arrives.
