As much as I enjoy the TFC Hercules Constructicons (even if I do fear for their screws rusting into oblivion), it always bothered me that their heads (aside from Scrapper) felt so far removed from their G1 counterparts that they just didn't work, Classics-ish designs aside. My plan was to buy the KBB downscaled CW Devastator and perform headswaps. Ideally I would have liked to know if the sizes were comparable to do it at all, but no place I asked would give me an answer, so I gambled. Turns out only Long Haul's head was suitable to replace his TFC's counterpart, but since his was the farthest removed design-wise, I still call that a win. Had to convert the KO head from a balljoint cavity to a mushroom-peg cavity by building up the shape using gorilla glue, then had to sand down and repaint the back of the head to properly fit into Heavy Labor's chest cavity for Dump Truck and combined mode, in the end, I'm satisfied with the results.
It looks so good. Is it impossible to replace the heads of other members and Combiner? I don't like Combiner head of Hercules.
The other heads are just not appropriately sized. All of the original CW heads are too big, and the KBB downsized ones are too small, aside from KBB Long Haul who just happened to be the correct size even though the back needed to be sanded down a bit to stow away properly. It was quite the depressing discovery, exactly why I kept asking everywhere if it would work, but at least it worked for one of them.
Looks awesome...nice work looks nice and posable too....are you going to do every character except Scrapper? Wait...screws rusting into oblivion...I better check mine!
Long Haul's head is the only one in scale with his TFC counterpart. The other ones are too small to use unfortunately. I saw a thread some time ago about someone reporting the screws on their Hercules had rusted without them noticing. I'm looking at the screws in mine now and they're definitely taking on a copper-like tint, it has me concerned.
