@ImperialOfficer: Nice finds from the expo! I'm sorry for the broken joint. If you know a dental technician near you, I'm sure he/she can help you.
I would fix it like this:
Please, read completely before following the steps and consider if this instruction is an option for you.
1. Use super glue to fix the joint (done - your broken part is successfully repaired! But it won't last for long...)
2. Mix a two component silicone rubber to make an impresion/mold of the now fixed part.
3. Check the mold if the imoression is authentic. Break the part again. Yes, break it.
4. Take a dremel or sandpaper to reduce just a little bit of the plastic and roughen both sides along the edges. You can also use sandpaper. Be very careful and avoid that the plastic get too hot and melts away.
5. When the gap between broken piece and leg of the AT-ST is about 3 mm, put the loose pice into the silicone mold using just a small drop of superglue (you can use a tooth pick to apply it).
6. Use a two component (dental) resin to fill the gap and let it polymerise it under 2 bar of pressure. I would use a dental resin because it is very tough.
7. After about 30 minutes in the pressure pot, the resin should be polymerised completely.
You can take the piece out, remove the silicone mold and work by the fixed area with fine sandpaper.
This is actually about how dentures are fixed in dental labs.
I hope this could help you. I also fixed broken parts like this because new/added resin is always more stable than a glued edge.
@Tamer: Wow, this is a package of greatness! So many goodies! Is it xmas already, again? SDCC is just around the corner! That makes me very happy! Maybe some day I will attend, too.
