[Steam-engine] boiler feedwater injector conection

[Blake]

Rick,

If the only hole in the top of the boiler you can use for your 
feed line is only 1/2", then you may need to open it up to about 
1" pipe in order to weld an extension on a bushing line I 
described. Kinda hard to do it if the only opening is 1/2" Maybe 
someone else has a better idea...
