Haven't done much tray work and have a job coming up which may involve a fair bit of containment, have you guys got any tips when working with tray ie forming your own bends and sets.
A hacksaw, straight edge and pen/pencil is all that you would need. I would personally just buy preformed stuff as its quicker to install, even though your initial cash outlay for materials is more expensive.
All I can suggest is that a good supply of tea or coffee and bacon butties will always help any work that may be a bit repetitive, measure, cut fix, measure cut, fix.
