Curious as to what the best type of glue would be for my project. I am converting a special Eldar Autarch. So far, all model pieces were plastic. I use a very cool plastic glue that actually melts the plastic and bonds two plastic pieces to each other.
Unfortunately, I had to use some metal pieces to get what I wanted. So here's my question; what would be the best glue to use for bonding plastic to metal? I've had poor luck with both super glue and JB Weld in the past. Is there a particular brand that works well?
Also, the metal pieces are somewhat hanging off the back of the model, so their weight might make a normal bond unstable. It needs to be uber strong!
It sorta depends on what you're working with. You say the pieces are hanging off the model, but is a sizable piece touching the autarch? Maybe it's hanging down his back or legs? If that's the case, a two part epoxy can work well. Be prepared to hold the joint for several minutes, even if you get the fast bonding type and have some sort of a brace set up so you can walk away after the initial set and let the glue fully cure for at least several hours. It's not an easy job, but it works pretty well. It's doubly better if you can somehow work a pin on the connection. Also, be careful if you're still working with the model and you get a little water on it (like if you use greenstuff). Not all epoxies are water resistant and if it's not you'll be a mess.
Otherwise, superglue usually does just fine. If you have a small area of connection, I think it's the best way to go. It might also be worth looking into seeing if you can work some greenstuff into or around the joint to tighten things up. As always, a pin will make things that much better.
Ever thought of pinning?

I use Krazy Glue. Works like a charm.
Course, pinning will help lots, as will greenstuff reinforcement afterward.
Loctite super glue
I use the super glue gel, stays in place, doesn't run all over, and sets very nice.

bah! 5 minute two part quick drying epoxy. mix the two parts up, wait 4 1/2 minutes, apply with a toothpick, wait a bit, then you have an uber strong bond that will last forever, unlike superglue.

You can use a file to smooth a tiny bit of each piece. If both sides are smooth, a small layer of super glue will hold them very strongly because of the increased contact area of the glue.
Pinning works well also.
Try Zap brand superglue, or JB KWIK epoxy.
Zap makes lots of really nice modelling superglues (which should be used along with pinning where possible), so they should have something that's right for you.
And JB KWIK is pretty much the same as JB WELD, but it cures in 5 minutes, rather than 30 - 60. Admittedly, it's not quite as strong as the slow formula, but I've yet to find a Modelling related use where 1800 psi bond strength qualifies as anything other than massive, senseless overkill!
On a random note, what's your plastic glue? Tenax? Ambroid? That Ambroid clone, Same Stuff?
I use LocTite Superglue GEL- its a Wal-Mart special, and its the best glue Ive come across. Why? because its thick and goupy enough to :
A) hold things in place better than half dried school glue while it sets
actually does that thing Gel superglues are supposed to do: fill gaps by themselves
All in all, second to none untill you get to 60 second 2 part epoxy. But for plastic to plastic, melting-style plastic glue is still the best- because it actually welds the bits of plastic into on contiguous piece.
