Hi PD's .... & thanks Peter [Webster] for the video of above and   to 'Tom the Builder'   .... looks good, sounds good & engine steam discharge  :boom just above water line apart from being truely realistic.. appears visually to have more impact than via the chimney stack  

So do I see a twin osciliator atwart ship just under & near to deck level or is it a twin horizontal with cylinder heads facing FWD?

The speed of the engine also sounds >>>high? so is it geared?... I am sure many PD's   :gather would like a little more understanding ...if you could forward this on to Tom Prior would be appreciated especially if  a response was in the offering   ... and again  :no1 build Tom

I sincerely apologise for the long delay in answering your post.
   The steam outlet is in the correct position,just forward of the port paddlewheel on this boat.
    The engine is a single cylinder slide valve type an
d single acting. It is very low powered but once under way really gets moving.
     The cylinder heads you see under the deck are painted on a wall which prevents draughts on the boiler.
      You are correct, the engine is high reving and geared to approx. 8 to 1 ratio.

Hi PD's & welcome Tom........we hope you enjoy our WEB site

Just when ever, some .JPG snaps of your steam plant and comments would not go astray.... however I am a little lost on....drafts affecting the boiler :?:  :?: ... I mean I could imagine this in :ohno  FROG hollow Scotland, but not in   OZ
