I also wound teflon tape around the base of the peek in effect stabilizing the nozzle and minimizing the contact between the nozzle and aluminum plate - to reduce heat transfer. That way the peek hopefully would stay as cool as possible.
I just about managed to finish this setup before the new print head arrived this Saturday. Unfortunately I didn't get to test it since I never got the extruder part working correctly. Given time that too would surely have worked - but no use spending time on that now.
Assembly of the MBE Extruder v9 was straight forward following the assembly pictures and videos on their web site. The only step that was unclear was if there were any extra steps necessary to install the resistor - since they only show the heat cartridge installation.
On another note; we received our laser engraver/cutter at the office on Friday so now it should get a little bit easier to machine some parts.
