The supply will be whatever it needs to be. I don't think torque would be a problem because the etching bit will most likely be small at the tip. I suppose the RPM will need to be in the 100k range to get decent cutting feed rates? I have model car motor I used for drilling circuit boards which worked well. I want to mount the motor on axis with the tool holder and keep the overall length as short as possible. I was thinking about doing this a while back and I'm now beginning to remember some the issues I faced back then. I may have come to the conclusion that the outrunner was not ideal. I need to think about this some more. I think my last plan was for a backyard version of a Tormach speeder: http://www.tormach.com/product_pcnc_acc_speeder.html Thanks for the replies. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
