Robert Stanton Posted October 11, 2015 Report Share Posted October 11, 2015 Hi I have a question for anyone who owns/used to own the master series arm. How were they adjusted for different weights/float points? http://www.steadicam-ops.com/docs/steadicam_resource_manual.pdf This manual claims there was a single adjustment knob for the arm http://www.google.co.uk/patents/US5435515 This is the patent filed for the mechanics of what I believe is the Master series arm, though it's never explicitly stated so feel free to correct me on that. Anyway in the patent there are a couple of ways described to adjust the lifting power and 'Iso-Elasticity'*. One is to have separate vertical and lateral controls for the cable terminations, the other is to have a single control which moves the termination diagonally downwards instead of straight down. There's also a third method described which is a simple vertical adjustment of the cable but I'm assuming this wouldn't be used since it's the crudest and simplest of all three. I'm just curious which of these methods actually made it into the final design Thanks Robert Quote Link to comment Share on other sites More sharing options...
Premium Members Victor Lazaro Posted October 12, 2015 Premium Members Report Share Posted October 12, 2015 I might be wrong but I was under the impression that the Master arms were simply vertical knobs, the zephyr and Flyer arms are with diagonal termination, and the G50/G70 have the two knobs.

Premium Members Jerry Holway Posted October 12, 2015 Premium Members Report Share Posted October 12, 2015 Lift knobs are not vertical in the MS arms. It's part of the magic of those arms - and the patent., from 1995, covers what became the Master Series arm. Quote Link to comment Share on other sites More sharing options...

Robert Stanton Posted October 12, 2015 Author Report Share Posted October 12, 2015 Ah thanks, I just find it quite interesting to see the ways in which Steadicam has tried to continually improve their products. Honestly the novelty of spreading the springs throughout the arm to increase the length still impresses me. Quote Link to comment Share on other sites More sharing options...
