Thanks for the suggestion. Its normal that fiber optics have more light coming out from the end than any other place, the inside is after all a reflector meant to make the light travel through it, its just not 100% reflective of course and some light bleeds out, which is a good thing because otherwise most of the light would come out before it would travel few inches. I dont think its true that light doesnt come out while its traveling through the cable though. Maybe in some types it doesnt or it does but the outer shells arent translucent to see it.
or as a last resort using normal cheap fibre optic cable and rough the outside with fine sand paper.
I didn't understand what this suggestion was for.
If there were at least some youtube videos I'd risk the wait. But there's only a handful that don't give any idea about the dim rate and no video for bent rods.
Interesting. What does 42 degrees mean though? I can bend a rod 179 degrees by having a tiny curve where it bends or have a very smooth bend along the whole rod so the rod takes a circle shape.
