that is very immpressive! I have never been good at working with angled pipe work. I am a refrigeration/air conditioning mechanic by trade so that should be a big concern!!!! no problem with pipe benders though
has anybody seen the flexible steel ducting? it is made from mild steel and is a corrugated duct-like product. good for using where there is alot of heat, used to use it next to hot water pipes and gas burner extraction systems for air vents. it was fully flexible and quite strong. maybe it could be used in areas like that??
