JB Weld or Epoxy?

What should I use to connect my case together (using Sintra), JB Weld, with Super glue or epoxy?

First use hot glue, then if you like how it fits, epoxy. But always make sure you can get back into the guts when (not if) it breaks.

Sintra is basically PVC, so if you're bonding Sintra to Sintra you can use PVC "glue" from the hardware store.. It actually welds the two pieces together, but slightly melts the plastic in the process.

You're better off using screws than chemical adhesives, that way you can take it apart to troubleshoot it. Use some crazy glue to glue small pieces of dowel with pilot holes (for self-tapping wood screws) or nuts (for machine screws) to the opposite side of the case's interior, to give the screws something to bite into. (Combine the two techniques if you have short screws.)

Do not use PVC cement from the hardware store!! That stuff NEVER comes apart, so if something breaks you have to ruin the case to get in there and fix it.

Well I am asking for making the case frame, I am using Sintra to make the external case, so I dont plan to debuild the frame so that is permanent

I am also trying to figure out sockets for nails/screws so I plan to use small sockets or nuts glued down to the case it self and screw it in that way.

Whats a good glue to glue metal on PVC and metal on metal?

And what is better for a Sintra/PVC case, pilot holes or nuts?
