Tetmatec, if you glue a hemisphere on the bottom of the tip it will scather the light, not reflect it back as it is a convex surface. The concavity idea is the way to go, and I believe only a very small one too as the surface that captures the light is small. You need to calculate the focus point at the place where otherwise you'd have the dimmest spot when using a flat reflective surface.
I use a chromy looking, adhesive backed, aluminium tape I bought at the local ABC Plumbing. I mostly cut it around a dime and poke a 1/64 diameter hole in the center of it. Some light escapes around it, some through the hole and it lights up the tip nicely. However, the more light you let escape to the tip, the less is reflected back into the blade. Hmmm, I think I'll cut my next reflective disk around a nickel and poke the hole. The last blade I made was nikel size and without the hole and you are right, it didn't look good. In the dark it ended abruptly and squarish looking.

I just placed my new blade and diffuser order with Tim. I also ordered an extra tip to do some experiments with, and if I need more I can take them off my other blades. I "think" the best thing to try will be dishing the tip slightly just above the diffuser tube so that it better focuses the light back down instead of outward and only inside the diffuser so that it better evens the light distrobution. I dont poke holes in my foil tape, as in the movies the light abruptly stopped at an almost flat tip-if I remember correctly. However, if this experiment goes the way I think it will, I will have them with and without holes,etc. and take pics to post so everyone can see the benefits and downfalls of my trials.

I am currently worling on an Anakin fx conversion and I was about to go and buy some 3/4" mirrors and I was wondering if poking a hole in the center was the way to go or is there another way to reflect the light back down the tube but still have the tip lit?

I would assume if you put a semi-reflective/ semi-traslucent material at the tip you would get both backlighting and light out the tip. However, I could be wrong as I havent tried it myself and others may have. Also if you did it that way it wouldnt reflect as much light back, it may not be enough light to make a difference.

Xwing,
I know it would still bloom, but the question was "anything besides mirrors with a hole to let light out but still reflect back". I dont know if he cares about blooming or not (wasnt in the question), but if he does your absolutely right. So far, if I recall correctly, everything blooms at the tip when using reflection to send light back down the tube. Hopefully we will have a solution to that soon. I will be working on it and I know lots of others are already. An LED blade that reflects light back down the tube and evens the light throughout the entire blade would be undescribibly cool!!!

I just finished my anakin fx conversion earlier tpday and i took the tip off and put a 3/4" mirror in the tip and put it back together and it took care of the dim spot in the blade.
