Not much have happened this last week but I did receive the earlex 3500 gun with a 1.5 mm needle and some paint supplies. Thanks MM for your help and time. To make the gun fit in my HVLP unit I had to do some small modifications to the adapter I had from a karcher vacuum. It's rubber so a Stanly knife did the job.

Now everything should be in place for me to start painting but...
Unfortunately while measuring up the screen for masking I noticed a slight curving of the top of the projected image. The screen it self is flat so this had to be an error in the newly acquired Epson EH-TW3500. The curving was about 6 mm. Luckily it's still under warranty and DHL is picking it up for service and are sending it to England this afternoon. It should be back sometime next week.
Leveling the screen and the projected image with laser:
Comparing to the top border center:

You can just about notice the start of the curving image on the right of the last picture. All photos were taken with my iphone so I apologize in advance for any offending quality.
