Steaming Timbers - Part 1

I had prepared all the equipment needed to steam and bend in the new timbers whilst waiting for the oak to arrive.
The ribs in Nanw are longer (2.5m) than those I'd ever fitted to a Redwing or similar dinghy as she is a rowing boat and not divided by a centreplate case.  Therefore I had to make a new steamer.  For this I selected a 3m length of 150mm dia 'spiral duct' of galvanised steel; a wooden disc plugged one end and a batten was made to run the length of the tube to support the timbers being steamed. Insulated by old duvets, discarded by my wife, all held in place by cable ties.
Steam is provided by a large old kettle with electric element removed and heated by a gas burner. It is also arranged to use steam from a DIY wallpaper stripper which can be only be used intermittently as the generator that supplies power to the shed is 'only' 2.5kVA and all the lights have to be off to power the steamer!
