Well, I checked my SW: Chronicles books last night and came up with a big zero for ROTJ shots. However, the prequel one did have two shots of the one used in Ep III. THOSE are definitely machined pieces with a tapered cylinder for a pommel. I'll have to get some scans on thursday and post them. That pike would definitely be the easiest to do, so I think I'll start there first while I grab more info on the OT pike. I don't want to draw up plans we can't all agree on!
Speaking of, here are some OT ref pics I found, all from either the movie or MoM.
This is supposed to have been from a MoM exhibit:
As were these:
Did find a nice pic of the emitter:
And this is a diagram from the jedi academy:
And a pic of the Gentle Giant figure for good measure:
Looking through these it seems like there are at least two, maybe three different styles of force pikes! Given the number made, it's not too surprising, but the variation is still pretty striking. The promo photo and one other shows the nice obi style pommel, while other have the more double wedge shape, and still others have just the wide cylinder with a taper at the top, much the same as the ones from Ep III. They are all tapered, but even the emitters vary between each prop. Except for the very odd emitter found on the "hero" version with the obi pommel in the promo shot, the rest typically just have 5 ring machines into the top of the pole, again like a prequel pike.
Now would SOMEONE care to make heads or tails of all this, please? :confused
