Col, I'm in central East Gippsland, Victoria. Just joined the Gippsland Model Eng. Society, so have a bit of company now. Where are you?
Eric, have been ME'ing for about 2 years now, and built several smallish stationary engines, mostly from plans that I have modified, and luckily they all work well so far. They are 10-12 mm bore, and I'm just gearing up to try 20mm. Having joined the above club, my wife is starting to hint that she'd like a loco to run there, so looks like my retirement hobby will be full on!
regards all,
lennard
