Metal covered model parts

These are some materials I use for models.  

 these are from Hobby Lobby, and a local hobby shop (model airplanes etc).
Getting these to adhere to wood is not always easy, I have used cya, and for flat parts spray adhesive, contact cement.  Generally I prefer to apply the metal to wood before cutting out parts.  But for edges or contoured parts it's applied subsequent to making the part.  I also use brass tubes, and hobby wire, or normal 16 to 18 Guage copper wire.  
To straighten wire from coil chuck one end in a drill and the other in a vise and spin while pulling and it will straighten out.
