New modified jaws for the Lancaster

We have modified the shrinking and stretching jaws for the Lancaster to leave sandpaper marks, NO LINES !

New jaws are stippled with a carbide welding process to leave marks that nearly equal 180 grit sandpaper grains, eliminating stress risers and potential cracks from your nice parts.

Our new jaws are on the top and the standard jaws are on the bottom in this photo.
