Been working on the first of seven chandeliers hanging over the stage house, now the first of 21 given the ball room was added with a different fixture, but no doubt similar requirements. Missing one of them, but seemingly easy enough to fabricate. Going RGBWW Neon and Marquee system lamps from TMB - so far... (Very expensive!!!, but the only RGBW 270 degree neon tape I could find, and the golf ball lamps while not bright (about 20 watts incandescent each) are individually addressed and RGBWW. In demo, yesterday... they were seemingly bring enough for the effect - Gen.1 lamps were used so new lamps will hopefully be better.
Problem now is that the main lighting for the theater is more a prop light.... still have to light the audience. Fixtures hang around 50' in the air over the main floor or 12' over the balcony. There is a central lamp socket at the center of the fixture which was on a separate circuit. In the past it was a R-Lamp in directional lighting. At the moment, looking to replace it with a T-Shaped LED fixture I forget the brand of. The larger OD of the T-shape is a large fluted heat sink which would look really retro bad.
However if I do another ring around this fixture’s OD heat sink to match the other two rings... It would certainly look almost as if it were designed that way. Than the problem... the Rosettes. I can fab. The ring and attach it to the heat sink, don’t have a source for the flower pedals. The central ball is easy enough to get.
A little Dremmel work with some scrap PVC solid stock and makings of a jig. Brought home three sizes of thin copper sheeting... but that won’t work in pounding out all 48x of them around this jig no matter how thin. Need to cast I think. Can’t be a flexible material casted with, or it will slump over the next 20 years, but also can’t be too fragile or it might break in transport or crack given it’s in a band around the heat sink - for the heat a powerful LED develops. Cheap and easy.
Thinking for mold just Plaster of Paris with just Vaseline or perhaps spray olive oil as a release. Easy to jig given the mold I made, easy to make a mold for four at a time with plaster - one at a time. Need to pound a #3 nail thru the center of my PVC jig and cut it off so as to make for a center mark of drilled mounting hole of the cast item.
Thinking 3M Epoxy gun in filling the molds/cast materials. Of those at home, DP-420 or DP-100 so far seem useful. The 3M Epoxy gun system sucks on website in figuring out differences or best for application. McMaster Carr’s website used to be more usefl on this product line also.
Figure though, if I get a epoxy casting, I can cut away the inverted parts of the flower pedals, and given a flat back - it won’t matter up in the air if stamped brass Rosette, or something of epoxy casting. Drill out and mount to a farmed out 6-32 internal threaded ball.
Epoxy if not too old shold take well to a plastic paint primer... than onto the color matching game for new ring and decorations. Thinking binder plate - flat head screw mounted, and welding flush a 1/16" aluminum banding. Taper the joint and flush weld, than either remove the plate or leave it. Sand blast the aluminum ring & color match paint It... More but initial thoughts.
Better way to make more of the c.1924 rosettes? Way over budget already in the addressable marquee lights and 270 degree RGBW mushroom Neon tape. My plan was much more simple... but Yes Sir! in doing what I'm told to do and it approved. I would like to do this detail cheap but will last at least 20 years.
