[modeleng] Re: Conway

Ken,

The mo' bigger the exhaust opening, the lower the velocity of the steam so I 
would open up the nozzle.  Meanwhile the gods of fire seem to have blessed 
you as regards steaming ability.  Only my Mich-Cal Shay has too much exhaust 
blast and I frequently open the fire door (not good) to cool the fire down.

 Hi

 I had Conway running this evening and I have a problem with the engine 
blower (not the steam blower).  It's so fierce that even when running I'm 
constantly blowing the safety valve.  Also I constantly have a shower of 
sparks.  This is enough to draw the fire into the bottom of the smokebox. 
The chimney top is getting so hot, it's gone a purple colour.

 Do I increase the jet size or reduce it to reduce the draught from the 
engine?

 Thanks for any assistance on this problem.

 Cheers

 Ken
