Well, thanks chaps. As a "lesser mortal" myself, kind comments are always welcome.
Problem now is: what's to be the next project? I keep looking a Find Hansen's web site – in awe! Looking at the web, several other people have seem to have had a go and given up, apparently leaving Hansen as the only modeller in the world making hot bulb engines. Let me know if I'm wrong. They are simply astonishing.
I did write to the esteemed Editor some months ago, asking if he could get a feature on or by him. Unfortunately the Ed. didn't reply. It would be a great shame for all that knowledge to disappear in the fullness of time.
Anyone else had thoughts on these engines? Probably needs a new thread.
Regards,
Norman.
