Re: New Lighting Blog Series: Types of Units
There is a HUGE difference between taking an instrument in both hands and panning it and it getting "bumped" out of focus.
The funny thing is I would yell at you if you worked for me for tightening the unit too tight.
All tightening should be only 1/4 turn past hand tight at the tightest.
Over tightening puts undue stress on all the members and leads to premature failure. In addition it makes it harder for the sparky that comes after you to focus the unit. To be tightened a unit should not be completely immoble.
In fact by your definition a light could never be "tight" because if I hit any unit hard enough or with a big enough piece of scenery it will move. Or if I can get someone strong enough (I have an electrician that I guarantee could grab the yoke of any unit you tighten and be able to move the unit with it) I can move it.
If you worked for me I would be angry at you for not locking off an instrument. If you can move a light left or right with the yoke bolt it can be bumped out of focus by a set piece or someone walking on the cats and therefor isn't locked.
