25th Joes are not meant to come apart. With the torso-joint moved up to the ribcage, there's no room for a torso screw, so if you want to swap arms, you gotta break the torso open, 'cuz it's glued. There is a method Hasbro endorses, involving a rubber mallet and a block of wood, but that was not something I was able to get to work.
Regardless, their parts aren't interchangeable. Lady Jaye's shoulders are too big for Scarlett's shoulders, so even if you could close the torso halves together, her arms wouldn't be able to move. I've spent a few days scraping away at the shoulders at various places with equally-various success, but I'm still having trouble finding out where the hell I need to scrape to get these halves together while not scraping away anything important.
At the moment, Dr. Biggles-Jones' torso is held together by her jacket, which I pilfered from a Biggs Darklighter figure from Star Wars. The jacket will do until Hasbro puts out a Dr. Venom or something, 'cuz there's simply no 3-3/4" labcoats out there for me to steal. At least, not the kind you can swap like a coat.
She also needs more paint here and there, I need to remove the paint from the hair and repaint it, since it's lost too much detail, and I need to file down her gloves and paint skintone over her hands.
Otherwise, hey. Sweetness.
Meanwhile, Comics Curmudgeon is back from vacation, and has bestowed upon us good tidings of Finger-Quotin' Optimus Prime!
