WHAT'S ON THE BENCH...by Véro

Un lance-tube. Fallait y penser!

Super de vous revoir ici
Et surtout avec de nouveaux projets, c'est bon signe

[nallouch01]

hihi, jean louis et ses fameuses "safety shoes"…

Elle revient comment, la lame, après le pliage?
Droite comme à l'origine, ou voilée?

Je me posais la même question...

[freddy1]

J’aurais bien aimé avoir plus d’explication sur les tests, et ce qu’ils doivent démontrer, en fait.
Je note qu’il faut couper une corde « à la volée », il faut donc que le fil soit assez fin et tranchant.
Ensuite, il faut couper une poutre en bois (pour vérifier la résistance du fil ?)
Est-ce que après tranchage de la poutre, le fil est vérifié ?
Et in fine, on plie la lame a 90°c pour vérifier la résilience ?
Le but, c’est qu’elle revienne à sa place initiale ou qu’elle ne casse pas ?
Enfin voilà, je suis curieux quoi…

Pour le test de pliage, c est plus pour tester les tth : il faut avoir un bon compromis entre la durete du tranchant et la souplesse de la lame (resilience=resistance au choc)

[Poil d'Ortie]

Un grand bravo !

[Opiwan]

C'est bon maintenant lache le tuyau pour voir !!



En tout cas bravo à eux pour le test

[kraspek]

J'ai du mal à imaginer une lame revenir en place, mais je dois me tromper, vu le nombre de personne qui pensent que ça revient en place. Quelqu'un ?

Bravo pour le test et comme mes petits camarades je suis content de vous revoir ici.

y'a le passage rasage de poils que tu as oublié (Gunthar va râler !) , avant et après découpe des madriers

[TORNACUM]

quelqu'un a pensé à virer ces photos avant le retour de Tigrou ?

[can]

Sauf erreur de ma part le bout du manche doit passer sous l horizontal et remonter au dessus de l horizontal quand on relâche. la lame ne doit ni casser ni fendre. Mais elle reste pliée il n y a pas de retour a sa forme initiale.

c'est un test destructif.

extrait du protocole (point 4: bending):

The Performance Test must be conducted in the following sequence:
NOTE: ALL TESTS MUST BE PERFORMED BY THE APPLICANT, EXCEPT AS SPECIFICALLY PROVIDED FOR IN THE ROPE
CUTTING. THE MASTER SMITH IS TO SUPERVISE AND SERVE AS THE OFFICIAL ABS WITNESS.
1. ROPE CUTTING: THE PURPOSE OF THIS TEST IS TO TEST THE EDGE GEOMETRY AND SHARPNESS.
The applicant is responsible for supplying the test rope and ensuring that it is a minimum of
one (1) inch in diameter. If the applicant brings a larger rope, the applicant will be judged
using the same criteria as though the rope was one (1) inch in diameter. The rope is to be
hung in a safe manner, so that the end of the rope to be cut hangs loose without touching
the floor or any other object. As a safety precaution, the rope is not to be hand held by
another person during the rope-cutting test. The hanging end of the rope is to be marked
with tape or a marker to clearly indicate the area that is to be cut. The cut must be
approximately six (6) inches from the end of the free hanging rope. A minimum of one (1) cut
must be made. The applicant is to aim at the mark with a two (2) inch margin of high or low
being acceptable. The applicant must sever the rope in two with one stroke. If the applicant
fails on the first attempt, the Master Smith will allow two more attempts. However, if the
Master Smith believes that the failure to sever the rope is due to the lack of skill or strength of
the applicant, the Master Smith may attempt the rope cutting with the test knife. This is a test
of the applicant’s ability to make a knife, not his or her ability to cut with it. If neither the
applicant nor the Master Smith successfully cuts the rope, the applicant fails.
2. WOOD CHOPPING: THE PURPOSE OF THIS TEST IS TO DEMONSTRATE EDGE TOUGHNESS.
The chopping test is to be conducted with a 2x4 construction grade wood stud. The 2x4 may
be either hand held or clamped into a vise or other safety device. A chopping motion (no
whittling) is to be used. The 2x4 must be chopped completely through a minimum of two (2)
times. The applicant may choose the area of the 2x4 through which to chop. Following the
chopping test, the Master Smith will inspect the edge to determine if there is any noticeable
damage to the blade. Any nicks, chips, flat spots, rolled edges, or other deformations of the
blade, including bending, will result in failure of the test.
3. SHAVING HAIR: THE PURPOSE OF THIS TEST IS TO DEMONSTRATE EDGE RETENTION.
After the Master Smith approves the quality of the edge, the blade will be returned to the
applicant. The applicant must then shave hair from his or her arm, using the section of the
blade that was most frequently used in the cutting and chopping portions of the test.
Enough hair must be shaved to demonstrate that the edge remains keen and shaving sharp.
4. BENDING: THE PURPOSE OF THIS TEST IS TO SHOW THAT THE APPLICANT IS ABLE TO HEAT
TREAT A KNIFE WITH A SOFT BACK AND A HARD EDGE.
The bending of the blade is the final test. Safety gear should be worn. The edge and point
will be dulled prior to bending. The Master Smith will mark a line across the width of the blade
approximately three (3) inches from the tip of the blade. The blade will then be inserted into Page 4 of 6
a vise, tip first, such that the blade is placed into the vise up to the mark on the blade. If the
vise jaws are very rough, smooth metal or hardwood inserts may be placed on each side of
the clamped portion of the blade to protect it when bending the test knife. The blade shall
be bent by force applied to the handle. A leverage device, such as a pipe may be used as
long as it does not pose a safety risk. The use of such a device is at the sole risk of the
applicant and at the discretion of the supervising Master Smith. The applicant will then bend
the blade ninety (90) degrees.
The supervising Master Smith will signal the applicant when the ninety (90) degree angle has
been reached. Failure on the part of the applicant to stop his bend immediately when
signaled to do so by the Master Smith administering the test exposes the tester to risk of test
failure, as any blade damage occurring during a continued bend after that point will
disqualify the blade. The blade is allowed to crack at the edge on bending but not beyond
approximately one third (1/3rd
) the width of the blade, leaving two thirds (2/3rds) of the blade
intact. However, if any part of the blade chips or any part of the blade or tang breaks off,
the applicant fails. The Master Smith shall determine if the extent or location of the fracture
line is acceptable. The decision of the Master Smith is final.
