Here's a couple "picture-takin'-stump" pics of where I'm at with the builder's kit.
I think the only other thing I've done is stamp that circle.
I've got it rigged up with random heavy things with "close enough" to 5/16" thru-holes, then I drilled out a length of steel rod on the lathe (haven't drilled a long hole through steel round bar in years, probably not since the last machine shop I worked at like twelve years ago, so THAT was fun), and drilled and tapped it for a set screw, to lock all the weights in. There's a couple rubber washers in there to keep the rattling to a minimum.
This was the rig I used to stamp the circle in the pommel. Ball Pein (or Peen) or machinists' hammers are MUCH better for beating metal than claw hammers, but I suppose not as great as blacksmith hammers. Still, give me a ball pein over a claw any day!! And some soft jaws are a must! I just make them from angle aluminum (I've thankfully got bumloads of scrap), nothing fancy. And don't forget a little wood on the underside to protect the pommel!
Oh, and here's an Obi-Wan Apprentice hilt I've been working on. Modeled it in Tinkercad, just playing around with it a little. I've printed a slightly different grip core with the rings spread out a bit more, but haven't got any pics yet. Haven't even cleaned it up on the lathe, yet. Anyway, I miss Stormpath, he did some great work. I based this model on pics I could find around the net of his, and a crappy pic of the book cover. It's A REALLY quick and dirty paint/finishing job, nothing final! Like I say, just playing around, I like to get a better idea of how a thing will look by doing "preliminary" (crap-fast) painting and finishing.
