I was installing fish processing machinery into a Russian shore based plant they also had an Icelandic engineer as well. Well this guy knew everything and yes he did lord it over me in a sort of friendly I know best way. But and it's a biggy I had a transfer roller missing that transferred the fish over the BA 51 skinning machine without being skinned, well this guy ( and he could have left me in the clarts) got a piece of polythene, disconnected two chain drives and low and behold we did a full days production with no stops with no skip roller. So sometimes it's good to listen and yes I thought I knew these Baader machines inside out but I didn't.
