Boiler tubes must be expanded to make them water and steam tight using a tool commonly called a roller.
Here Wayne rolls another of the 253 tubes. The machine he holds is an air motor which drives the roller.
Once all the tubes have been rolled, the next step is to form a bead on the end with an air hammer and special forming tool. - J. David
