jBURTONView attachment 157793 Oh sh*t, I have one of these in the attic. Also the ever classic 3m overhead projector that my generation is most familiar with. Mine is probably the same brand as this one, though I think its boxier, same shade of teal.
I also have a stack of old work propaganda posters that are straight out of the 80's, been meaning to dig them out and digitize them...
Yeah, did you guys have the nifty wing-dings sort of module for the pirate flag? I had that and a black flag on my old land yacht back in the day, always dreamed of making a helm shaped steering wheel for that beauty!
Oh it's a solid build, don't let the stupid video fool ya. We screw the retainer on, cut and miter lengths with a radial arm saw, and weld it up using pole clamps and c clamps. Cabinet depth is (desired depth - 4 7/32"). If it is any sort of sign with over 4 square feet, it gets a pole and steel saddles top and bottom like usual.
One primary benefit is making something look like an extruded cabinet at any depth, without paying for absurd flimsy extrusion that needs a subframe anyways. UL hasn't had any issue with it, sent some out of state without anybody even commenting on it. It's a good deal cheaper to stock than all sorts of extruded cabinet depths, just sticks of this and sheets of .090 aluminum (a 5x10 gives you 3 10' lengths that will build 24" deep cabinet's sides). We've even cut and grooved 090 like you would acm, (gussetted and welded corners as well) and built single sided wall signs with it.
I'll get you a few shots of a build next time one's in the works if ya like.
i haven't seen one of those in 30 or 40 years
do you have to crank the wooden handle to make the bulb light?
