Good afternoon!
Funny weather, so I stay close to my computer.
Concerning my Graham, it's a very nice piece of jewelry, and interesting to built, but:
I runned it w/ air for several hours, flooded w/ oil until the oil comes out cristal clear. The engine runned pretty well in & out , no problem at all. I was satisfied ,so I decided to fit it to the Boston and go to the lac right away.
Was the weather too cold this day or steam not hot enough??? But when the steam condensated inside the engine, it didn't come out normally,I then helped to flow the water out by turning the propeller in the proper direction.
Sh...! The crankshaft has turn but the piston was water locked.( I now have a nice scratch on the crankshaft). I tightened , more, the grub screw but my Allen key get loose. (Murphy's law).
I must notice & thank Graham for sending me US spare screws and Allen key free of charge.
For the time being, it is laying on my friend's bench and this winter, we'll see. We shall have to reinforce some points and seal the heads cylinders properly as I find the soft and leaky.This engine is probably too fragile for me : grub screws too small ,......So I get back to the D10 ,that I shouldn't never leave.

I'll post my steam launch later on to get your impression.
Sincerely.
