I've a well made Stuart Turner steam engine to hand. It just sits about by the computer and I twiddle with it when I'm on the phone.
I was doing this the other day and it came to me that it might make a good basis for a hybrid model. Drill the head for a model aero engine spark plug, arrange for points, a small battery and a supply of gas bleeding into the induction pipe. Sounds easy enough ................
It has the usual slide valve and I wonder how it might fare as an internal combustion valve, bearing in mind the minimal pressures it will experience - not going to race it, after all. ;o))
It is only an idea - what do others think?

Kim Siddorn.
