To make up simple light and above all effective instrument panels for your scale jobs then try this-
Obtain fron an art shop some artists scraperboard,this is basically a black ink over a ceramic surface,mark the instruments in place with a draughtsmans clear circular template with a sharp needle,no add the dials,pointers,switches,toggles etc to the panel (plenty of material on the net for the panel) cut the panel to shape and glue onto the fascia,job done !
