I don't recall it being in my TAIG lathe manual |
If you buy the lathe 'kit' is most certainly in the instructions. The basic concept is just like lapping valves on older cars. It is a procedure that must be done on the kit lathes to get the best fit and smoothest operation of the carriage/cross slide. You do not use a commercial lapping compound though as the parts that are being lapped are aluminum.
