Has anyone successfully identified the real problem in the legs. Applying Pledge isn't the proper fix, although probably part of it. I've popped apart everything I can on the legs. What it seems to be is the feet not resting flush. They seem to want to push inward, forcing the legs apart. I've trimmed any flash I can see. I'm just not sure what part to try sanding to make the feet sit how they're meant to. The swinging arm for the feet? The surface of the foot assembly that rests on the leg? Help?
The tabs just aren't thick enough. I used super glue on the pegs between the vertical fin, and the pegs on the legs. Let dry and I haven't had a problem. Never used future myself. Perhaps it's too thin and multiple coats are required.
Except, like I said, that isn't the entirety of the issue. Coating the tabs isn't the complete solution.
I looked into this a little while ago, although my findings are probably lost in the Combiner Wars Appreciation thread somewhere. Blast Off's legs have a number of issues that prevent a flush fit. 1. Tabs aren't long enough. One tab barely holds on for dear life in every mode except for robot, while the other just... Does virtually nothing due to its stubby length. This was retooled a bit for UW Strafe. Both tabs were made slightly longer, so he can actually keep himself together. If you don't mind permanent modification, you can do like I did and permanently attach Blast Off's orange-y/brown shuttle tailfin pieces together. You'd be required to parts-form it to his back for robot mode, but it helps keep him together. 2. Thigh(s) refuse to collapse flush. This is a problem for one thigh each on both my UW Blast Off and Strafe, although the former suffers more for it. The pin that goes through Blast Off's shin on one of his legs seems to have been fired in a less-than-optimal position. I removed said pin once, and his legs gave no resistance for Shuttle/Leg mode. I don't believe this majorly affects arm mode. 3. Hips and possibly feet? The ball joints for his hips stick out wider than his knees, causing some minor "pull-apart-itis" when you make use of his arm mode's elbow. I seem to recall something about his robot feet not being able to sit flat for his limb modes, and trying to move the feet by force would pry his legs apart. Overall the biggest design failure in regards to functional limb modes is because of his shin tabs. As previously mentioned, Strafe re-uses his leg molding, but flipped around and with longer tabs and can hold. The other problems I've mentioned only seem to exist as a result of his stub-nubs.
That's the thing. That's all I did and it's worked out for me. I figured that even if there were some differences in tolerances, having tight friction on the pegs would suffice. At least for me, it worked out.
