Hi, Adrian.

The easiest way is to use a text editor.  Just concatenate the two files 
together and replace the "END" record from the first file with a "TER" 
record.  Chimera should be able to open the combined file.

If you want to do it from within Chimera, use the "combine" command (see 
http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/combine.html for 
details) and then use the File->Save PDB... menu to save the resulting
