Default How Curved grooves for Wooden or Leather Fletches Were Cut Into Gothic Quarrel Hafts

Two line drawings, after 1505, from Martin Löffelholz's Nuremberg scrapbook started in 1505. They picture devices to cut slightly curved grooves into cossbow quarrel hafts for insetting wooden or leather flights/fletches to give them a more accurate ballistic spin as they went.

500 year old machine based mass production.
