Fiber optics are installed and covers glued down. A few things I can note about all this.
1. The LED is epoxied into the bottom of the oil pan, and centered as best as possible. I bent the leads at a right angle to facilate fitting.
2. The LED required a 300 ohm current limiting resister. Not having a 300 ohm, I used two 150 ohm resisters in series. I was able to fit them within the assembly.
3. I decided to route the wiring through the transmission. Going through the front would be difficult hiding wires within the front assembly. Also--the front of the assembly rests on the frame and wiring may only complicate things later. Going through the transmission seemed the lesser of two evils.
4. Once past the engine block I formed each fiber optic strand so that they rest on the brightest portion of the LED. That being the top. That gives the maximum light transference.
5. Each strand was positioned then glued at the engine heads.
6. With each strand secured I fed them through the valve covers, and then glued the covers down.
7. I kept the strands long so I could clip them to the length I want after.
8. I decided to exit them as nubs, sort of like a light plug. I nixed the idea of running them like sparkplug wires because that made it too much like a conventional engine. That I don't want, and in the end, I don't think it would have been as visually interesting. The brightest part of the optic is at its cross section, not at it's side.
9. Once clipped, I sanded and polished the ends.
10. I used Pledge Floor Care Finish to coat the acrylic light ports. It always amazes me how effective that is to clarify. The difference was stunning. It really made them pop and it provided a deep clarity.
11. The light ports are not secured yet. When they are secured, I will position them deeper into the block. I didn't want to position them that way for the photo because they are tight fit, and I'd risk damaging my work later. I still need them out.
12. I tested the lighting after all this, and I feel it looks pretty darn cool. I will image it for you as I get further along.
What's left? I need to fill some joins, mount the light ports, mount the front voltage converter assembly, do a final clean up, then it's into paint.
