(more box ways) was re:Re: Accuracy of ( was Linear Slide Components

Elliot,

From this and Georges' previous post:

Hopefully you can see that things get difficult when we try to talk
of a "typical" construction for a machine part (box ways) which may
range from a few inches to many tens of feet in length; and which is
used in a machine from mouse size to house size(and bigger). Also
consider the words "expensive" and "big". Do they mean the same thing
to all of us when speaking about machines?

Hope this helps,

Ballendo
