Hi
Another little job that seems to have taken all day.
The snifting valve as shown on the plans has a length of 3/16" pipe silver soldered into it and the other end has a nipple and nut to connect it to the outlet on the wet head.
Mission impossible
I have modified the snifting valve by silver soldering a threaded connection into it. Making up a pipe with nipples and nuts each end was much simpler. There isn't a lot of room working inside the smokebox.
First job was to drilla 3/8" hole in the side of the smokebox
Temporarily fit the wet head with super heater
Fit the smoke box and connect the steam pipe
Make up the snifting valve pipe
Fortunately the chimney isn't riveted to the smokebox so access through the top is possible
Another trial fit
Cheers
Rich
