About 70 exhibitors have showcased scale models from sailing ships to working railways at a two-day expo.
The Port Macquarie Model Expo attracted about 300 people in its first two and a bit hours on Saturday, July 13.
Port Macquarie Model Expo spokesman David Connolly said there was an excellent variety of scale models on display.
Exhibitor Paul Haskew from Ellenborough displayed model trains set in a small village.
Mr Haskew said the hobby was relaxing and he wanted to show people there was more to do than sitting in front of a computer.
Retired engineer Richard Dawson said making scale model ships involved research and understanding.
That ensures the scale model ships are accurate in nature.
"You use drawings, usually from dockyards or museums or technical books, and private photos from the internet," Mr Dawson said.
The Port Macquarie Model Expo continues at Panthers Port Macquarie from 9am to 4pm on Sunday, July 14.
Entry to the model expo is by gold coin donation with proceeds going to the Mid North Coast Maritime Museum.
