Rolling or expanding boiler tubes ; just imagine a big spike with a tapered roller bearing the spike stuck through the bearing so that if you push it further up the spike the rollers were pushed out (expanded)this was pushed into the end of the boiler tube given a good whack with the short handled sledge hammer then turned by a handle like you get in socket sets (the straight rod that fits through the hole in the end)this pushed the tube out against the end plate , hopefully sealing the leak ,you did'nt know If you were successful until you had a full head of steam on again, the plugging was like two round end plates with a bar through the tube wich was tightened up to seal the tube , getting near time to leave her if you had to do that to often, mind you I'm talking 1950/60s it was all water tube after that
