Dial Indicator tear down, inspection and repair

Got a bunch of dial indicator which arrived in rather poor state. This shows how to take them apart and bring it back to life. The pack of 6 are labelled "Coventry Grinders Ltd" The 2 DTIs are made by Kennedy and Verdict, also a Mercer and a Mitutoyo which do need some work. Just been to an auction and acquired a whole box full of Mitutoyo electronic indicators. Video of those now up, see    • Mitutoyo Digital Indicator repair   (c)2016 www.dynoguy.co.uk
