Mixtec blowgun Tlacalhuazcuahuitl depicted in the Codex Bodley. Many cultures have used such a weapon, but various indigenous and aboriginal peoples of East Asia, Southeast Asia, Western Europe, North America, Central America (the Huehuetenango region of Guatemala), and South America (the Amazon Basin and the Guianas) are best known for its historical usage.
Sumpit were generally made from bamboo, but they can also be made from wood. They were usually about 4 to 6 ft (1.2 to 1.8 m) in length and 2 to 3 cm (0.79 to 1.18 in) in diameter. They can be made from one piece or from two to three pieces joined. Sumpit used for war generally used thick wooden or palm leaf-rib darts.
Blowpipes have been in use for hundreds of years, but were first documented by John Joseph Griffin in his 1827 book A Practical Treatise on the Use of the Blowpipe. [1] Blow pokers are multifunctional fire irons. Primarily they are used to arrange the embers or firewood in a wood fire (the poker), secondarily they are used as a blow pipe.
It consists of a 1.2 m (3 ft 11 in) tube, with darts approximately 20 cm (7.9 in) in length. Unlike modern Western blowguns, the fukiya has no mouthpiece: instead, a shooter must maintain a seal with the lips while forcefully exhaling. The darts used in the fukiya are called fukibari. Traditionally, fukibari were 5 cm (2.0 in) in length.
Dead-blow hammers are used in woodworking to knock joints together or apart without denting wood components. [2] In metalworking, a dead-blow hammer can be used to properly seat the workpiece against parallels in a machine vise. [3] [4] Dead-blow hammers are sometimes used in orthopedic surgical procedures.
Lumber, pulpwood, shingle bolts, and whole logs move at different speeds and were prone to double-up in a V-flume’s low grades and curves. Finally, box flumes could move an unprecedented amount of material, up to a maximum capacity of 300,000 board feet (710 m 3 ), or three times as great as the maximum for a V-flume.
Log driving is a means of moving logs (sawn tree trunks) from a forest to sawmills and pulp mills downstream using the current of a river. It was the main transportation method of the early logging industry in Europe and North America .
The development and completion of that specific log boom in 1851 made Williamsport the "Lumber Capital of the World". [1] As the logs proceeded downstream, they encountered these booms in a manner that allowed log drivers to control their progress, eventually guiding them to the river mouth or sawmills. Most importantly, the booms could be ...
