Okay, so I caved and bought the Encore head mold things to go with some old Ratchet and Ironhide toys I've got. Now, I had been planning to do this whole mod with them years back, where I would move the arms and create a backpack out of the back of the seperating cabin section. Inside of that, I wanted to store the head and have it flip out, then make the whole thing mount on the 'chair/face-sticker' segment in bot mode. Well, I never did get around it, but I did experiment with my Ironhide a long time ago and placed his arms up on top of the screw mounts. Anyway, these heads came along, and I knew I was going to combine the new parts with my old idea. Everything arrived last night, and I set to work this morning. The Ironhide experiment worked out nicely enough, and I applied it all to Ratchet--whom turned out better as a result. In the third and fourth pics, you can see I had to do a little cutting of the actual custom piece. The obvious part was modding the back panel to allow for the pin heads that were now in the way. You can see the little corner-cuts around the swing pins on each side. The cool thing here is that the bracket piece acts as a natural clamp, holding the pins down. The second mod was cutting into the actual toy frame, where I cut out a segment to allow room for the pin head. Leaving the part at the top also acts as a natural clamp--something I didn't do for Ironhide when I cut the same section out of him some years back. Now, this makes them both official partsformers, as you have to take the arms off and stick them back underneath to transform him. Those that don't care for that sort of thing can either skip this, or come up with some kind of swing-piece for the arms to swing around at the shoulders. But that's beyond me. Oh, and someday, I might configure the backs of the cabins into backpacks that can be removed for both forms. I figure, if they're already partsformers, might as well keep it going, eh? In any case, I'm very happy with how this all turned out. Granted, they're still kinda wirey, but they look so much better and blend in very well with the other G1 toys. Finally, these two have normal heads, and a decent bot-look to go with them!
