Why all the fancy ways to torque a nut? Simply make a spanner wrench with a 1/2" square hole on the end of the handle, and use a ordinary torque wrench. The only difficulty, is calculating the torque multiplication factor: http://www.freeinfostuff.com/TorqueExtension/TorqueExtension.htm Years ago, I had a special spanner, for rebuilding a Mercruiser outdrive, that came with a sheet of paper to calculate it's torque multiplication. I stamped the formula into the end of the tool, so I wouldn't loose it. I no longer have the tool, but the principle is the same. The one I had looked similar this: http://www.iboats.com/mall/image/vendor/16/bigger/18-9803_big.jpg -- MC Cason - Assocaite Developer - Eagle3D Created by: Matthias Weißer http://www.matwei.de/doku.php?id=en:eagle3d:eagle3d http://developer.berlios.de/projects/eagle3d/ ------------------------------------------------------------------------------ Everyone hates slow websites.
