<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><u>In the 1970’s we mounted a die grinder in the tool-post of the lathe and then used a grinding tool in that to remove the outer shell of the bearing and then regrind the laygear
to accept a bigger bearing or a bush. Once that rear laygear bearing has started to fail, the laygear gets very hard and conventional lathe tooling wont work, even tipped tools can struggle to get thru the hard layer. Over the years, the tooling got a bit
flasher but the idea never really changed. Doing it by hand can be a disaster, because if you leave a ‘groove’ or dent in the laygear housing, a replacement shell type bearing will never last.
