In Reply to: Pritchell hole? That's a good one. posted by gmharris [71.105.36.203] on Monday, February 10, 2014 at 12:16:18 :
A hardy hole is to hold tooling like the hardy or a mandral, while the pritchell hole is there just to drive pins through...but a shop press with the heavy press plates with V and semicircle notches also works really well.
