This weekend is the North Shore Railway Modeller's Association 36th Model Railway Exhibition at Forestville. I always enjoy these shows but for some reason my two daughters were too busy to attend this year.
It's a wonderful sub-culture with lots of great craft being done by talented enthusiasts. I particularly like the work of the Warringah Model Engineers. These folks fabricate machines out of metal and are clearly very skilled with the metal lathe. I understand that you can now buy a decent metal lathe for around AU$3,000 which will allow you to work aluminium and brass.
Members build things like petrol motors, steam engines, and stirling engines (including one so efficient it runs on the heat of your hand).
The club meets on the second Thursday of each month at the Urobodalla Hall, Aquatic Drive, Allambie Heights, Sydney.
I mention this fact as they don't have a web site. (I guess they're hanging back to wait and see if this internet thing will last).
