Hi

I`m looking for some info on building a oscillating based on these
plans:
http://npmccabe.tripod.com/45engine.htm

Most of it seems OK but I can`t understand the inlet and exhaust
arrangement.  There is a detail box B which shows the exhaust as
straight but the inlet is a L shape.  This is my second build ( first
McCabe Runner succesful) I might be missing something really simple
but if anyone has built a engine of this type and can explain the
valve arrangemet I would be most grateful.  Other tips also welcome.

Thanks

Paul

Isn't it simply a mixture of space available and where you want the inlet 
and exhaust connections to point?

You could ask on this site, they tend to build a lot of engines from bar
stock on there, so may find someone thats made it.

I did a screen print to PDF of the "better (and clearer)" print, and was 
able to zoom in to the "Frame" drawing. It seems to me that "Note 'A'" 
is a detail looking down on the top face of the frame, and "Note 'B'" is 
  is a cross section through the frame at the point indicated by the 
arrows, as seen from the right hand end looking along the frame.
I hope this helps.
