Jan 11, 2015   //   by Bob Warfield   //   Beginner, Blog, Manufacturing, Techniques  //  1 Comment

Our last survey of 2014 (we barely got it in by launching it December 31st!) was all about what methods folks were using to affix workholding (vises, clamps, fixture plates, and so on) to their milling machine tables.  Here’s the result:
