Marv,

Wonderful story and background. The involution profile jaws are a great addition to the shop. Your aluminum drops gives us hope there may be an aluminum extrusion that may be available for general sale. Your advice about going page by page through the tool catalog is so true whether being a novice or an expert because there is so much to learn (or be reminded of what was forgotten) and image.

Thank you for the posting and excellent photos,

Paul
