Quickie about door hinges

Hi Gilles, for kit bashing, I use various size/thickness polystyrene sheets, rods, tubes etc. with brand name Evergreen here in the US. I have seen them called plasticard and other names elsewhere and I assume, but can't be sure, they're also just polystyrene.

Polystyrene needs to be chemically welded to form a strong bond. My preference is liquid "cement" products like these.

Liquid cement can be brushed on, or just dabbed onto a joint between parts. The "thin" ones will enter the joint via capillary action and "melt" them just enough to form a bond. This is ideal for small parts, or for long seams where you can go along and dab glue on the seam every few cm.

For larger parts, e.g. the panels I cut to connect the kit floor to the roadster tail, it takes a lot more glue and more working time to get the parts to fit, so I use the thicker brushed on cement like the "Mr Cement" above.

For smaller detail pieces either of the thin cements are fine. I prefer the quick drying cement when "tacking" parts. Other than setting time, there doesn't seem to be much difference. They all work well for my purposes, but unfortunately I have not had good luck with the "SameStuff" product.

When I need to join different materials, CA glue is my preference. I have a selection, as well as the accelerator to force it to set immediately if needed AND the debonder to use when I screw up.

More or less any brand of CA glue will do, but beware that CA glues will "fog" nearby surfaces which can ruin clear plastic and require additional finishing for other plastic.

I have also used a variety of epoxy glues but only rarely because they are a bit of a pain to deal with. I have not seen "Araldite" in many years, but I think it's also a 2-part epoxy. It should be strong enough for anything.

I plan to experiment with epoxy to glue in the nylon hinge faces. If that works well, then "job done". Otherwise I will try to capture them as Colin suggested.

In any case, for what you're doing you might need to use MORE polystyrene glue.

Chris.

Thank you Chris to have written this long, well-documented response, almost a tutorial👍

I also use profiles from the brand Evergreen (plasticard is, I think, a generic name)

Maybe I’m not generous enough on the glue layer as you advise...

I will try the CA glue, the BSI brand is not sold in France but there are others, no problem

Wait and see...
