Joel was from Cleveland and worked at Cain Park Theatre a few years before I did. I received my first training in the lighting biz there from his successor. He had quite a reputation at Cleveland Heights High and at the Park. Theatrical Lighting Practice is one of my stand-bys..

Sounds like more "technology for technology's sake" to me. What's wrong with good ol' flush handles & valves? No batteries or power and only needed a washer replaced every 5 years or so--maybe.

Sorry for any confusion. My experience has been with "Broadway" flats--1x3 framing, 1/4" plywood corner blocks & keystones, muslin covered. "Hollywood" flats will be heavier and will probably require stiffer battens (5/4x4, maybe?), longer nails/screws, etc.

Lay your flats on the floor, face-down, in the shape you want (in your example) 8x12. Batten them together with 1x3s, vertically on both sides of the 2 vertical flats with the battens extending "up" 4' to cover the top flat. Use keystones (1/4" ply plates) to space them out on the horizontal...

The socket in your picture 9801 is a Medium BiPost., as is the male end of the adapter in the first post. We used to have them is most of the Kliegl 6" lekos, both 500W & 750W. Wasn't aware that B&M used this base in their kegs too. The leko lamps were all burn BU, while the Fresnels PCs...

(Which "other side of the circuit" are you referring to?) No, not unless there were other loads on the same circuit such that the total load on the circuit exceeded the OCD rating, and the OCD failed to operate.

I'd guess not fake. High-wattage appliances can do this to receptacles (and plugs.) My 2nd guess is that in this case the space heater had a damaged or corroded plug prong causing a high-resistance contact which (seriously) overheated. The load (1800 W for a space heater, maybe) was probably...

Again:: What happened to all of our students??

There are devices made for making & breaking circuits under load. They're called SWITCHES., not "connectors."Isn't there something we're supposed to have learned w--a--a--a--y back, maybe when 5 yrs. old: Use the correct tool for the job.

(Where are all our students??) Anyway, Ideally one should neither connect nor disconnect things under load. Disconnecting under load will result in an arc between the parting terminals and (in the case of these mini-pins such as socapex) possibly damage them seriously, depending on the load...

One of those LD jobs which ain't B'way but it's a buck.

If you have 3 phase motors in the system (hoists, etc.) that have directional controls ("UP-DOWN") the motor must be powered by the correct phase rotation in order for the controls to indicate properly. (It would run if phase was reversed but the control indication would be reversed, which...

Bull, Just dealt with a similar project. I'll email you tomorrow.,

Please keep us updated on the project, thanks!

How many tennis balls are we dropping here? If "a lot" (couple dozen or so) I would suggest a square box with double doors, hinged at either the US & DS sides or the SR & SL sides of the box. Any trapdoor on one side only is likely to allow the balls to "roll" off of the opening door, going...
