Trouble gluing different plastics together

By Force Majeure, in Imperial Assault Painting and Modification

Hi all, I'm new to modding my IA figures and looking for advice:

I am having trouble gluing plastic parts from traditional models (made of polystyrene I think) to the figures from IA, which is a more flexible plastic. I've tried super glue of course (cyanoacrylate) and bought some Tamiya brand modeling glue, that "welds" the plastic together, but no luck. The Tamiya bonds model parts very well to other model parts, but not to the Imperial Assault figs. What do you guys use?

I want to change the poses & weapons that my Trandoshan hunters have, to make them unique. I cut off the arms and head to reposition them.

I had used some green stuff to hold things together, but the arms were still sort of wiggly after curing for a day. That didn't work to my liking so I cleaned the green stuff off. I ended up drilling holes to pin them, but I still want to find a glue to join the pieces together a bit more solidly.

Here's a pic. Sorry for the poor quality of the image, but you can get the idea from it anyway.

Thanks.

I was hoping to hear from anyone, but I guess I'm the only one with this issue?

Well, just in case anyone else has the same problem that I've encountered, I've come across a solution that works perfectly. Its a two part plastic bonding system for difficult to bond plastics. It uses a felt tip marker (the activator) and glue. You mark both parts where you plan to bond them together, let it sit for 60 seconds, then apply the glue to one of the two parts. Hold it for 30 seconds, and that's it.

After bonding I was able to drop my figures into hot water to re-position arms or stances without anything falling apart. My figs are modded and ready for primer and paint. I'll post pics as soon as I'm able.

Here's the glue/bonding system that I used:

Honestly, there's no reason why Cyanoacrylate shouldn't have worked...

It could ahve been that the cut lines were too smooth, so a tiny amount of scoring would be the answer to getting them to join...

I mean, I don't know exactly what plastic the IA figures are made from... But if its ABS (Same sort of stuff as Lego), then Cyano would be the only way to get it to bond with Polystyrene.

Certainly, a Poly Cement wouldn't have worked, as you found out... I'm just always completely and utterly offput by the melt-and-weld applications on the small scale.

Maybe my lack of patience was why the cyanoacrylate didn't work for me... either way, here are some pics of my work in progress.

There's some clean up left to do, so they're not quite ready for prime-time. I hope to have them painted soon, as time allows.

Good results, regardless.

Is that a Ghostbuster proton pack on the one?

Not intentionally... maybe I should name them accordingly: Winston, Egon, Ray and Peter.

Got these finished a about 10 days ago. They're not competition level, but they will work for home games.

They look really cool mate

Apologies: i kind of skimmed through: are you pinning the separate pieces at all? Pinning helps a lot.

I also use the same cyanoacrylate that is intended to glue model race car tires on. I believe it has rubber or latex (?) added to the formula. It makes it less brittle, but also seems to slightly alter how it "sticks."

Looks nice. I guess you got the gluing completed. I was going to say look at 3M adhesives. The type industry and autobody guys use. It is usually denoted with a number on the bottle and I think it's #24. $30 glue that doesn't fail and glues most anything -forever.
