David sent us these photos and a suggested method of fitting the SFX20 Diesel sound into a scratch built tanker wagon.
David used the following:
"Cardboard toilet roll centre cut to size and stapled
Black foam sheet from Hobbycraft cut to size, wrapped around the cardboard and painted using a tester pot
Assorted plastic bits from sprues to add realism
Bogie taken from an old Hornby Tanker
Removable end piece made from balsa, painted black
Decals from ebay"
Thank you David
