Hi everyone, this is my first post so I'm sorry if this is a well asked question. I have a master replica Luke lightsaber and the retaining pin (blue arrow) no longer stays threaded to the saber. I was able to remove the plate (red arrow) from its mount in the saber (green circle) and have determined that for some dumb reason the thread inside the plate has just worn out. I didn't remove the blade that much over the time I've owned it but whatever. Is there any resource for parts I could use? Chance to upgrade this to a better looking pin, perhaps with a red button to better match the movie one? Any advise would be welcome.
