Hi, I'm not sure if they're pin joints but I've taken photos of my ROTF Sideswipe for you guys to confirm. In case the pictures don't show it's the one at his elbows. His pin joints are rather loose lately, and I was thinking of purchasing this to tighten it: Tamiya Extra Thin Non-Corrosive CEMENT 40ml MODEL Would you recommend it? Thanks. (Edited to add pictures)
I've always just used a drop or two of superglue on the pin, then kept it moving to allow it to run down into the loose area, and after about 5 minutes, it was good to go. The trick is to keep it in motion so the glue doesn't dry and lock the part(s) in place. Once you're done, it should be a little tighter than before and still allow movement. ONLY try this at your own risk though. I'm just sharing what I've used in the past that worked for me (most recently on my G1 Dinobots to tighten up some joints and pins). Good luck, man.
mampy suggested before, using a layer of future finish. (jeepers! is there anything that stuff can't do? )
Pardon the zombie thread (I found it while searching for pin joint repair), but does anyone else have other tips for tightening pin joints? My Animated Shockwave's knees are pretty loose...
