Hi RevanReborn,
Absolutely :-)
Believe it or not, that was actually the easiest part (although I did start with a little trial and error ;-)
I have to state though, that this technique will not work with the ultra-edge blades since they are colored enough that you cant really see the other filtering agent through them.
Also, this works Best with the Midgrade Blades, but it does work O.K with the Heavy duty blades.
Take out your saber blade and look down the tube.
You should see that the film US uses is hot glued in place.
I simply used a sharp scalpel (you can use an exacto-knife) to gently scrape away the hot glue.
Then reach into the tube with a pair of needle nose pliers and pull out the film.
(If you are careful, you can save the film for another use. )
If you have one, cap the end of the tube so it doesnt get any dust down it.
Now you are going to need a dowel of some sort that is about 1/2 to 3/4 the diameter of the blades inner tube and your new diffusing agent.
I found that party city had really useful transparent "Cello Wrap" of many colors.
US uses about 7 to 8 feet (yes feet) of clear diffusing film (because it is clear).
You will only use about 18 inches, even less if it is a darker color.
Then (in as dust free an area as you can muster) measure out the length and width you need for your new film (about 1 inch less than the length of your blade by about 18 inches) and cut it.
Then tightly wind your diffusing agent around your dowel.
Now completely insert the dowel with the film around it into the blade tube.
Release the film, and it should unravel to press up against the inside of the tube.
give it some gentle shakes and you should be able to remove the dowel from the tube and the film should stay in place (you can always gently shake again and it should go down in proper place).
Lastly, hot glue the end of the film to the tube.
Wow Sifu John, that's some impressive custom work! Looks amazing, both the hilt itself and the colour

point awarded. I know you've been getting bombarded with questions lol but do you mind if I ask how you removed/ installed blade film? The thought occurred to me for some stuff I'd like to do in near future, but I wouldn't know where to begin.
