[modeleng] Re: Conway

Thanks for the advice regarding the blast hole size.  I'm in London at present 
but will try opening it out next week (and fit a spark arrester) in time for 
the BHR steam Gala on 2nd July.
 
Cheers
 
Ken

Hi Ken,

I have had this problem and solved it by increasing the diameter of the 
blast pipe. I did it in increments of 0.5mm until I had the desired amount 
of draw on the fire.

Cheers,
