Talk:Backlash (engineering)

Both purposeful backlash and unintended backlash due to wear
The lead currently says "backlash is purposeful clearance between mating components", but it should be adjusted to convey that backlash may be either purposeful or unintended and due to wear. For example, the cross-slide of an engine lathe may have started life with, say, 0.010" worth of (intended) backlash between its leadscrew and the nut; but after 50 years of service, the backlash has increased to, say, 0.080" worth, through the nut wearing out. — ¾-10 21:58, 30 October 2007 (UTC)


 * Made various edits. Cleared up purposeful vs. undesirable. — ¾-10 04:17, 11 November 2007 (UTC)

Mathematics to Gear Tooth Backlash
Changed section title to make it clear the subsection pertains only to gear tooth backlash. Other types of backlash require different treatments. Hope to come back after some research to fill in with other types of backlash. Vic (talk) 22:44, 11 August 2009 (UTC)Vivers

thou as a unit
You might want to avoid using this unit, as it makes it very difficult for anyone not familiar with this uncommon unit to understand the meaning. Especially for people who use the metric system. — Preceding unsigned comment added by 145.120.9.26 (talk) 16:34, 24 September 2012 (UTC)
