6″ Vertical Boiler- the ID plate

Last task before the boiler inspector.  The unique identifier.  In my case the VR-18-18 code is stamped on the boiler in a safe location, or engraved onto a plaque which is silver soldered to the boiler shell.

I chose the latter method.  And used the opportunity to put my name and date on it.


CNC’d the info onto a brass plate, and bent it into shape,  I use V-Carve Pro for engraving jobs. 


Then silver soldered it into position.   In this case I used a lower temperature silver solder… “StayBrite”, so I did not risk melting the previous joins.
