how can I make lightsaber hilts? is there a tutorial somewhere?
It's a model is it not?
The bit you hold your hand on(the handle/hilt) it's a model.
but how do I make it?
You have to use a program for it, go here http://www.gamingforums.com/showthread.php?s=&threadid=5669 and look under modelling software. There you find a couple of programs you can use.
