There's lots of resource on the web for model engineers and quite a few blogs that were started and ran for a few months. Here's a few I've recently found that have stayed the course and are still quite active.
Start Model Engineering
John Somers got into five or six years ago after many years working on bikes, cars and even dabbling with clock making. Start Model Engineering is full of tips and guidance for someone wanting to get into model engineering and he even has a guest expert John (Bogstandard) Moore to provide tutorials on the basics.
A mile stone event for Machinists Blog this year, it's been up and running for 2 years. Based in the USA it has a good variety of articles on engine building, upgrading your machine tools and free plans. A small team of people write for the site and there is also a forum to discuss your ideas and issues.
Wongster from Singapore has been blogging since the middle of last year. His articles on upgrading his machines to CNC, making tool holders and setting up a workshop are well written and full of pictures. Wongster is not afraid to show you where he went wrong and has produced some excellent results.
Jan Ridders model construction
I found Jan Ridders model construction via start model engineering, Jan is from the Netherlands and has kindly reproduced the site in both English and Dutch. There are a whole range of model engines on the site from Stirling and Flame Gulpers to Internal Combustion Engines. Jan can happily send you plans for the engines if you email.
