Thanks everyone, and your welcome Shadow. I used a peice of black foam for the emmiter extension. It came from a broom that had the thin foam over the wooden handle. It worked quite nicely, but I have trimmed it since I took that photo. I have to say, I saw a "stock" ROTJ in some photos and the black really makes it look slimmer. Like when I where a black shirt I look thinner then I really am. But this has really brought some character to the saber and I love it even more then before. You really feel as if you have Luke's saber, only when it was new :) And their is that sense of accomplishment.
If anybody wants to attempt this I say go for it. There are a few different configurations for this saber and Im glad I could show another version. Plus if when/if the paint starts to wear, i'll just have a "weathered" edition!!
I still would like to find some way to make the emmiter top (not the extension, but where it comes out of) have a larger diameter. Obviously nothing massive, but if it was slightly larger then it would agian trick the eye that the neck is even smaller then it really is. Almost like MR upped the size of the hilt say 40% larger then an LE, but left the emmiter top original size and forgot to also make it 40% larger.
