Quoted from indypinhead:
That looks like a tricky one...
Without having an assembly, for testing, I doubt I'll be making this drop target.
I don't think it's as tricky as it seems. The only really crucial change is the pockets under the little flanges on the front. The target lifter uses those and holds the target up with a pulsed coil. The hit to the target knocks it off the lifter so it can fall, and the coil goes off when the switch at the bottom is triggered. CC wouldn't even really need the light socket, as there's a light essentially pointed right at them with the arrow in front of the target. You could throw a 2 head flex in there for more direct light, but it wouldn't need a new socket.
All the fluting at the top part, and the bit of a bump out behind the pockets, is just for strength I think. With the machined polycarbonate, I think you could just make the whole top part solid.
The pockets under the flanges are about 0.3in across, just under 0.4in tall, and about 0.1in deep (I don't have anything real accurate within reach of my desk). The whole head rectangle could just be 1/4 thick solid. Whether or not the bump outs are necessary for strength in the poly - I don't know.
I guess another minor caveat would be that the faces would have to be polished/smoothed enough somehow that the decals could be applied and stick well. Trying to carve out face renditions in the targets would suck.
But I would LOVE to see these made.
