Hi,
I'm a professional engineer, having spent most of my years designing structures and machinery.
My hobby has been the construction of a 71/4" Mikado 2-8-2 loco and tender, which is now almost completed.
Weighing out at 600kg and about 3.4m in length (loco + tender). Draw pull 170lbs or 77Kg.
I also enjoy inventing and have filed about 40 patent applications covering various aspects of engineering.
I enjoy technical challenges.
Regards,
Jack
