A solid start. Where did you get the t-tracks (handgrips)?
I still have my first saber - a Luke ANH. It's sitting in the kitchen next to the garbage where I've been waffling on tossing it for a couple of years.. It's starting to rust a little, mostly the ears. Can't remember what I cut them out of.. Had no t-track back then (Hey, this WAS early 2000.) I used foam insulation. They've 'migrated' from their original positions and are bunched toward the bottom. Used a door peep-hole for the glass eye and kludged a 'red button' from hardware parts. It was a fun build, I must say.
