My current lathe has stepper motors, and stalls if asked to push a big drill, so in fact my 2kN number was derived from asking FS-Wizard what the push force was an a 25mm drill. However, when pushing a big drill I am not as concerned about Z axis acurracy. I was looking for numbers to plug in to FEA calcs of my Z bearing housing design. This is an interesting puzzle, as there are advantages in keeping it compact to keep the screw/nut as close to the work as possible. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Monitor Your Dynamic Infrastructure at Any Scale With Datadog!
