Small (JR-CSM) – Large (JR-SCL)
Our Tapered Carving Screws are the better alternative to the conventional carving screw. The tapered part of the screw is turned into a pre-drilled hole in the base or back of the carving and tightened by using the hole in the “T” handle. When the screw has penetrated the wood deep enough for secure holding, the rest of the screw is passed through a hole in a bench or a slot on the carving arm. The “T” handle, which is also the nut, is then threaded onto the screw until the work is pulled tight against the bench. Considerable pressure can be put on the screw by tightening the “T” nut. If the carving needs to be rotated, loosen the wing nut and position the carving, then tighten again. No need to drill a deeper hole like conventional carving screws.

Accessories-06-2ViseClamp-New
Pointing System (JR-PTG)
The Pointing System is designed to accurately transfer points from a Model or Maquette to a Carving Blank. Why work from a model? Creating a 3-D carving requires the establishment of many points, not necessarily lying on defined two-dimensional planes. Using the Point System allows the carver to “reach in” to points that cannot be measured using 2-D drawings or photographs.

  • Accurately transfers points from a model to a carving block
  • Create a 3-D carving
  • “Reach In” to points that cannot be measured using 2-D photographs.
