Hi Graham,That engine is slightly different to Ron's one as the drawing shows it having a 10" diameter flywheel with curved spokes.To give a bit more of an idea of size the base casting is 12 1/4" high to the centre of the bearing. Jo
I believe it is but I have not seen it yet.I do not know what an ALF is.Jo
I haven't seen that one before.Do you have any others Jo
Hi Graham,Are the patterns still around for the Hornsby, or would it be possible to purchase a set of plans from you? I helped to preserve and operate a full size 12 1/2 horsepower Hornsby for a local windmill and spent many happy hours in the engine house on open days. The attached photo shows the engine, still in its original paintwork, exactly where it was installed in 1923.RegardsRayW
Graham, your mention of the Brayton engine peaked my interest. Are you planning on making it with constant pressure combustion. What is the bore and stroke you will use? I have been messing with a replica of his patent model which gives me a few teasing spits and pops, but nothing continuous. There is a fellow in California who has converted a steam engine to a Brayton cycle. I believe his is a 4x8 bore and stroke . Shame about the foundry, would have liked to see the finished goods. Paul
Hi Graham. I am intrigued. Without any drawings,how did you build in the first place? Did you scale down the measurements from a full size engine?
