Re: Stiffness and Rails

PJH,

How tall is a tree? How blue is the sky? How big is a boat deck beam?

Point is, there are so many variations of linear rails and their
support structure that we would need more information to give a valid
answer, IMO...

Consider that a choice can be made to use a stiffer structure with a
weaker "rail system", or a strong rail system and weaker structure;
both giving equivalent results...

Hope this helps.

P.S. If you look in the message archive and follow some of the links
on the Faq's, you will see pics of(or links to) many machines...
