angle grinder

had to go to this job yesterday.they wanted new heater fitted to a zan w/m.what had happened was they got 3 3inch nails caught in m/c and had damaged heater when removing it.husband opened door and showed me how he managed to get nails out.he cut 2 slots with an angle grinder about 3 inchs long in inner drum from rim down and peeled back to remove nails. he seemed quite pleased with his handy work and said to me what do you reckon then.i said it was very good if it was food processor he was trying to create cos what he had done was going to cut everything to shreds.i hadnt thought of that he said :oops:.i was going to take a photo but did not want to embarrass him.
