My latest and greatest V2 to date, what I finished recently.
It's got all the features of my previous trials (four piece construction: nipple, emitter, hilt/body, pommel) but now incorporates John Bunker's drawings, and the collar that Mr. Alinger quotes into the final design.
I've used paper shims to pressure fit the bearing and collar (steel in my current set-up) together, and then another to fit the bearing/collar set-up to the emitter, and the results are...miniscule. It could easily not have been there at all and wouldn't have made a difference in the ease of the emitter's spin. As a matter of fact, it spins better on just the collar alone. When I wedged another paper shim into the windvane to pressure fit the collar into it, it actually caused the center rod/drive shaft more difficulty in spinning the entire assembly. Nothing that I don't think the original motor couldn't handle but I worry such a set up would tear the threads out in the soft aluminium for the grub screws.
Speaking of, there are two each in the emitter for securing the nipple. One to hold the nipple in place, and then another on top of them to keep those grubs in place. Considering how often my threads have torn in previous trial hilts, the prop guys must've done something similar to keep them in place, resulting in the grub screws sitting near-flush to the surface of the emitter.
I'm debating whether or not to actually try and motorize this piece but the problem is that I hate having duplicates. If I turn this into a functioning stunt, I'd have to keep it that way and make another V2 for my collection as the RotJ belt-hanger. I'd hate to do that, but I'm really curious about how well it'd function as it was originally intended. Decisions, decisions...
In any case, the run is one step closer to happening. I'm considering applying this set-up to the V3 but I'm hesitant as we don't know much in how that was made.
