Last week I received new copies of the Winfred M. Berg catalogs, both inch and metric. Filled with machine components: gears, polished rails, bearings, sprockets and pulleys. Everything you'd need to develop a high-tolerance, precision mechanical device.I once had the catalog practically memorized, I used it so much. Little has changed since I first opened its pages some thirty years ago.
If you need to make a machine and you don't have your own machine shop, this is the catalog for you.
