When your on the path, one must know how far they have come and how far they have to go.. And so it is with machining. From blue prints to planing the job, you have to have the means for establishing how much you have cut and how much more you have to cut..
Given the media intensity given to the Covid 19 (otherwise known as Corona or Wuhan) virus, there seems no reason to have posts on that very specific subject in several forums Accordingly, all of those posts will be moved to "Headlines". All new items on that subject should be posted there as well. This notice will expire on 1 April, or be extended if needed. Thanks, folks.
