Got a 2.5 kva Lister alternator I'm tinkering with as a Winter project and the roller bearing on the pulley end of the shaft was complaining; one evening later and it was out. Got myself into a certain industrial services place near me and even the chap behind the counter was shocked, over 100 pounds (before VAT). My lip must have curled up a bit or eyes stared a bit harder because he then said it would have been over 700 pounds retail. Lucky for me I must have been grubby enough or something and he thought I was trade.
When I was walking up the path towards the counter I thought, now what about a spare, walking back - unprintable.
Any experts tell me how you come to over 100 pounds ?
