Humble beginnings
« on: November 29, 2018, 02:27:58 PM »

Good day all,

   Long time ambition has been to get into model steam engines. Nothing doing for years while I got together the wherewithall to make something. After a couple of false starts I settled on the River Queen launch engine. Now I have been in engineering for !! years (censored to due extreme age) and I'm still trying to figure out how anybody could put this forward as a beginners project ! However, persevered and (having made almost everything twice) would like to post the results of my first effort here for your amusement. Still a bit of finishing off to do: have to attack the connecting rod (too wide and fouling on the bottom of the cylinder), shim the valve and to install the plumbing. I believe the valve has been a bit of an enigma in the past: I will be pleased to share the results my efforts in this respect within the next couple of weeks.

cheers John Kearsley

Nice work. Is your engine going to be put in a boat?

Since you mention it . . .

   Also many years ago, my very first model boat build was going to be the Bowman type steam launch "Celia May"  (Traplet plan 1429). I sent off for the plan AND the vac-moulded hull kit (cost thirty quid then - plus postage to South Africa). To say I was disappointed with the hull kit would be the understatement of the year. So it got sidelined while I went on to RC sailboats. Back to today. The plans for Celia May suggested the Unit steam engine. At first it seemed to me that the River Queen was quite a bit bigger until I put them side by side. Much the same size, but the C of G of the River Queen must be quite a bit lower. So it looks like Celia May may have her day and the River Queen may have a home on the water (assuming I can get her to run).
