So on last minute notice.. Or at least getting to it now in being busy last week in asked to only look into buying some storage tubs so as to rain protect some Studio Color fixtures from the rain for a one-off but will be outside a few days. Easy enough - some storage tubs as similar to what’s used for drip caps say on snow machines.
I finally grabbed a Studio Color and measured it up. Mounting holes 17.13/16" on center and given non-fan cooling, I really need some form of either large trash bag thru something hard body drum liner rated for high temperature of at least 22.5" in dia. (if I remove the handles) thru 24" in dia. Some form of origionally requested and thought of just upside down storage tub won’t work with a moving light unless huge and expensive.
Figure as long as the designer don’t ballyhoo the ceiling too much, but would want at least a +45 degree angle to the hinged axis of the fixture, I can’t for during show rain bag go lower than 16" in protecting the base but not the fixture head. For after show / night use, I need bags to go down to 24".
Did I mention for the one-off, it’s 76 Studio Colors... sorry, wasn’t mentioned to me either before tonight or I will have moved it up on my schedule for figuring out sooner in a busy last week. Renting enough Tempest domes or what ever are not an option given this amount of fixtures.
So I came up with a few concepts, priced them out in hopefully available on time and with various prices. (To the project manager... you ok with these prices?) McMaster Carr 8852K77 , 9772T34 , 9772T63 , and 9772T17 . This in addition to industrial grade trash bag as new to me tonight in concept but mentioned.
Tried the trash bag and one of the drum liner’s for prototype tonight. Not sure which one if any of them in having an extra drum liner lying about for a drum full of bad moving light lamps extra. Two different options for rain bags other than I think the hard shell liner or the high-temp. versions I don’t believe I’m using. The rest of the samples ranging in price of the trash bag from a few cents to a $36.51 hard shell drum liner for 76x fixtures with most ranging in the $15.00 range... budget no doubt will play a huge amount of a role in options and probably the trash bag in end result.
Both samples were suspended by a 23.1/2" disc of 3/8" plywood. The 55gal. heavy plastic drum liner got cut down to 24" high and at 16" a ring of nylon tubing connected together as a weight and stop got epoxied to it with DP 810 adhesive as best available for my epoxy gun and in stock. Worked well in this ring now attached to the bag by way of a lot of spring clamps for clamping ring to bag before and while gluing. Rest of the plastic given I matched the 23.1/2" plywood undersize for the bag ring was easy enough to fold up outside the ring of bag after dry. Heavy gauge tarp as made for a drum liner works well with that ring 16" down in folding up the rest of it below that ring at 24" at the expected mover range of the fixture.
For an under mounted fixture, I think these 55gal. drum liners are the best option with a few of them available to choose from - thickness obviously good but high temp, also good as a concept as also good should there be a whoops or temperatures exceed TBA testing on a fixture. 15ga. plastic is a little less user friendly but if high temp. is something to consider that I’ll be playing with in the morning. It’s also the second most cheap in the above and given most won’t need rain tents for fixtures in that quantity, might be a good idea.
Works well as a concept in glueing in a bottom ring to a drum liner with 3/8" x 23" dia. top. Might increase the dia. slightly to the top to more match that of the actual O.D. of the drum liner plywood insert, but overall it’s a good start. This in not increasing the O.D. of the ring below it in being easy to fold up the lower part of the bag to the outsides when in use.
My opinion, such a heavy gauge plastic liner to a 55gal. drum works well for rain tent to a moving light. Down as much as needed during production and flip down the rest after the show.
Tried a different version also tonight - the trash bag. Cut the same plywood top ring for it, but overall in marking of it’s maximum height, left off it’s bottom even silicone filled for weight tubing weight in that the O.D. was much larger. Instead I glued the edges of the top plywood donut to the trash bag, and weighted it. Concept developed as I glued the bag, you would use the trash bag at night in lowering it, but during the show, it would be gathered up about the top of the fixture as best possible during the show without protection of at least the base part of the fixture. No protection during the show for at least most of the fixture, but much cheaper. Also, questionable rip and or mis-aimed light resistance of the bag - but certainly cheaper. Harder to mount also but at a few cents per bag cheaper. Also, given the thickness of the bag left it long. Glued it to the top ring of plywood but after that, free floating. Length of bag will help given it’s un supported by thickness or lower ring.
Should protect the fixture sufficiently at least after the show - this assuming it as a plastic trash bag don’t get blown into a hot heat sink and just melt. Still though, the say 23.1/2" plywood ring epoxied to the trash bag will work if left long. A little less controlled but much cheaper. No protection during the show, but sufficient protection during the show.
Yet to get in the other concepts such as hard liner, but think that wouldn’t work as well as what I already have given a hard shell won't hinge down unless added to it hinges and stays. More just what of them verses trash bag is best verses what’s cheapest. Trash bag will no doubt win out for the one off... other options above no doubt best overall in offering some protection durig the use and afterwords, rolling down the rest of the bag...
Next Lighting Techie / Inventor could gain their fortune from inventing something short of a Tempest dome in only some sort of roll up, roll down, bag for protecting moving light fixtures from rain that's economical and will protect the primary sense under a light storm, and can be say rolled down to fully protect the fixture once the storm or night is over. Not aware of any sort of tent for moving lights that can be rolled up or down so as to protect them from out doors. Cheap enough what you invent... that's your next million dollar or at least widget of the year invention start to your career.
Have at and have fun.
