Attention to detail is critical when you are working with Machine Tools. When I restored my Bridgeport I wanted to use R8-ER32 tool holders and wanted to torque the holders using a torque wrench. I was disappointed to discover that these custom torque wrenches could cost as much as $1,000 when I really wanted a torque wrench adaptor.  So I set out to make that adaptor, and I’m pleased with the results.
