"Herringbone" isn't a term used in the industry, as far as I know. They tend to call them "double helical" A double helical gear needs one element to have axial float to share the load equally. A double helical rack and pinion with deliberate axial thrust would give a backlash-free drive for a router table. I once saw a large _triple_ helical gearbox at David Brown's (where my dad used to work). That's a really stupid idea as the gears can't float to equalise load. (My dad pointed it out to me with a "They thought that was better in 1930, can you tell me why it's a stupid idea?") -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
