systeme de tension d'un lit a corde????!!!

[cupidon]

salut à tous!

ayant trouvé la motivation de (re)faire un peu de matos cet hiver (et non completement en panique une semaine avant la première sortie!!!) j'ai, à l'aide d'un menuisier membre de ma troupe, realisé un lit a corde tiré d'une iconos flamande daté 1473.

la réalisation se passe nikel jusqu'au moment ou on s'est alors posé une super question qui tue:

"C'EST QUOI LE SYSTEME DE TENSION DES CORDES????"

si quelqu'un a des infos la dessus je lui serai reconnaissant a vie!!!!!!!!

merci!!

Eh bien, quelques noeud astucieusement choisis ?!...

Un bon noeud de plein poing et quelques demi clés font des miracles. On appelle ça un noeud de tension.

Un début de réponse par là :

How do I get the ropes tight enough so they don't sag?
It seems very difficult to get the ropes tight enough with only one person. I use someone to help me (after the bed is laced). Each person sits on the ground on opposite sides of the bed. I start by sitting near the foot and bracing against the rail with my feet and pulling the first rope as tight as I can. I then hold the rope on the outside of the board with my thumb, and tell my partner to pull the next rope. (I hold with my thumb so I can get my fingers out of the way.) My partner pulls the rope, and then holds with his/her thumb and tells me it is OK to pull the next one. Normally, I am able to put enough pressure with my feet that by the 3rd or 4th rope I pull, the 2x6 rails of the bed are starting to bow inward (as shown in the photo above). We let them bow and continue working our way towards the head of the bed, alternating back and forth, pulling it as tight as we can. The bowed rails keep the bed tight, and even after two weeks at Pennsic, I have not had to tighten the bed once. In the picture of the bed, you can see some bow in the side rails. It takes about 5 minutes to tighten the bed after it is laced.

If you still have problems, then simple wedges between the ropes and the bed can be installed, and if each wedge is hammered down (taking up another inch of rope), then it is really easy to get the bed incredibly tight.
