I can find the VCMT inserts, but not the lop-sided tool holder it will take. I also stopped at Grizzly, and there is a GO704 in the back of my GMC now. I'll have to clear a place to put it, so ATM the rear of the p-u is tarped against the weather. Screws and a motor kit will be ordered before the next 24 is ~30~. Then I need to find another computer, but D525MW's have trippled in price since they are discoed. > EBo -- > > ---------------------------------------------------------------------- >-------- One dashboard for servers and applications across > Physical-Virtual-Cloud Widest out-of-the-box monitoring support with > 50+ applications Performance metrics, stats and reports that give you > Actionable Insights Deep dive visibility with transaction tracing > using APM Insight. > http://ad.doubleclick.net/ddm/clk/290420510;117567292;y > _______________________________________________ > Emc-developers mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-developers Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
