A bandsaw (also written band saw) is a power saw with a long, sharp blade consisting of a continuous band of toothed metal stretched between two or more wheels to cut material. They are used principally in woodworking , metalworking , and lumbering , but may cut a variety of materials.
There are multiple techniques for constructing band saw boxes. The primary technique starts by cutting the main shape of the box. Then a 1/8" to 1/4" piece of wood is cut off what is to become the back. The drawer shape is cut within the main shape, which involves cutting through the main body, and the body must be glued back together.
A resaw is a large band saw optimized for cutting timber along the grain to reduce larger sections into smaller sections or veneers. Resawing veneers requires a wide blade – commonly 2 to 3 inches (52–78 mm) – with a small kerf to minimize waste. Resaw blades of up to 1 inch (26 mm) may be fitted to a standard band saw.
The saw filer uses a semi or fully automatic grinding machine for this. Saw bands operate under high stress and heat and in the presence of wood chips. Carbon migrates into the steel from the wood. Gumming prevents case hardening and fatigue cracking of the saw band gullets. Resaw Bandsaws (teeth on one side only) may be left or right-handed ...
Residual stress in a roll-formed hollow structural section causes it to gape when cut with a band-saw. In materials science and solid mechanics, residual stresses are stresses that remain in a solid material after the original cause of the stresses has been removed. Residual stress may be desirable or undesirable.

A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge used to cut through material. Various terms are used to describe toothed and abrasive saws. Saws began as serrated materials, and when mankind learned how to use iron, it became the preferred material for saw blades of all kinds.
A ring saw is a form of bandsaw where the band is rigid, rather than flexible. This requires the band to be circular, rather than the bandsaw's usual oblong [1] of straight runs between two (or three) guide wheels. Ringsaw blades are abrasive rather than toothed. The brittleness of this abrasive coating, and the need to avoid flexure, is why ...
