Boiler tubes (in profusion)!

The tubes are ready to fit…!

After what must have been an epic session, Nigel and his assistants in the southern group of the “Boiler Collective” have now cut, deburred and bent the 600+ tubes for the three boilers we are building.

The pictures below show the extent of this activity, and the bending jigs they made…. (thank you men)!

We first made a trial set by measurement from and comparison to the drawings (yes, yes, I know “never scale from drawings“), we then test fitted these and they were good. So then the team cut the rest using an angle grinder in an adjustable jig. Then cleaned up the ends with a bench-mounted wire wheel, and finally bent them to the appropriate angles using the bender we “pre-calibrated” in the trial run.

EPIC….
