This simple video show the finished weld of the boiler end plates.
The end Plate is 3mm which sits on 80 Nominal Bore pipe, the wall thicknes of pipe is of a similar thicknes. Note there is a second 3mm plate tack welded into the inside of the pipe. The second plate has the same hole pattern as the external plate with slightly smaller hole diameter, this gives the front view of the locomotive a stronger  presence.

Note these plates were welded using the GTAW process, you choose the process you want to weld with which is dependant on skill level, for secondary school students i fing the GMAW / Mig process to be more appropriate. Only use tig welding to weld up the locomotive if the student has the skillset to do so.
