What is a sinusoidal stake used for?
This small sinusoidal stake is perfect for anticlastic raising. Its wave like pattern means you can curve the metal in two directions. You will need to have a raising hammer.
What is a sinusoidal stake?
A multi-curved stainless steel mandrel for anticlastic* raising. Specially tempered. * Having opposite curvatures at a given point.
What is Anticlastic raising?
Anticlastic Raising is a technique of metal forming whereby sheet metal is formed directly with a hammer on a sinusodial (snake-like) stake. A flat sheet of metal is shaped by stretching its edges and compressing the center so that the surface develops two curves at right angles to each other.
How do you make a Spiculum?
Making a Spiculum
- Grade roll a sheet so one end is thinner than the other.
- Cut a shape from annealed sheet and file the edges smooth.
- Lay the metal along a groove in a wooden block.
- Reverse the form and and repeat the hammering along the opposite edge.
What is Synclastic and Anticlastic?
Anticlastic surfaces are those in which the centres of curvature are located on opposing sides of the surface. This is commonly-described as a saddle shape. Synclastic surfaces are those in which the centres or curvature are on the same side of the surface.
What is funnel stake?
Description. Funnel Stakes can be used generally for hand forming of funnels and similar conical items in Beaten Metalwork or Tinsmithing. They are so named because of their original use in the making of Tinplate funnels or Tundish.
What is a half moon stake used for?
(d) Half Moon Stake : This stake has a sharp edge in the form of an arc of a circle, bevelled along one side. It is used for circular folding and seaming.
What does Synclastic mean?
: curved toward the same side in all directions —used of a surface (as of a sphere) that in all directions around any point bends away from a tangent plane toward the same side —opposed to anticlastic.
What is the forming shell?
Seashells are the exoskeletons of mollusks such as snails, clams, oysters and many others. Mantle tissue that is located under and in contact with the shell secretes proteins and mineral extracellularly to form the shell. Think of laying down steel (protein) and pouring concrete (mineral) over it.
