Dave the gas loco Gail built was a model of the Hornsby-Akroyd oil engine 0-4-0 Lachesis which was supplied to the Woolwich Arsenal in 1896. This was an 18" gauge line the model is 7/8" scale on 32mm track.Cheers Dan
I hope that whatever put you in Hospital is a closed chapter behind you
A great running engine & a great project!
I do not think that you should expect to get it to run much slower
i was assuming, from what i have read and understood, (model engines are far from my academic degrees!) that with a longer stroke, my engine will give its peak torque at lower rpm, nearer from the wished "put put put put" and not the usual screaming note.
