The problem I have with sliding pins, is that to have the pins slide there must be at least some clearance in the location system. That's why I like the Hardinge system. I found a similar changer here: http://www.issintl-inc.com/latheturret/ > on a side note... when you huys see HAL, do you think of it as 3 > letters, like LED or SUV, or d oyou think of it as a single word, like > the name... kinda like shallow Hal? noticed you referred to it as > "an HAL module" and i usually think "a HAL module" which would imply > it's being said as if it were a name.

But now that I think about it, HAL doesn't seem to describe a particular entity. Whereas Hal might be thought of as the application of HAL concepts to a subsystem within EMC. You got me on this one. I'll watch to see if there any compelling arguments either way. Now that you mentioned it. I noticed some people using "than" when I would expect "then". -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending) ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
