Hi RoyI have been mAaking a scratch model from anything in my bits box where I have an abundance of balsa wood and ply offcuts together with brazing rods and bought brass strip and sheet, so I have run across the problem of which glue to use many imes .The windows of my lifeboat have a frame rivetted to the cabin shell, and I thought best to make the frame fromplastic sheet, so I found out purely by accident that balsa ceent stuck plastic to ply wood very well indeed, the reason being that the balsa cement was a solvent for the plastic, and the liquid plastic bonded to the rough surface of the ply like you know what to an army blanket. If there was any advice I could give you about using adhesives, I would say,ensure that surfaces to be bonded should be immaculately clean and the surface to be bonded should be keyed by roughing it up with a light abrasive. personally, my favourite is a two part epoxy resinbecause it never fails. For anything metal, I always use silver solder, and for wood of any sort, I use PVA glue.
Have a play, and use up scrap bits as test pieces , glue them together and see what turns up, see how the adhesive reacts with the material you are using and put the results in your memory store for future use
