JMG Posted March 1, 2010 Share Posted March 1, 2010 là ou je suis perplexe, (car le travail est impressionnant à voir ainsi)c'est comment testes tu la phase de tir, car ton vérin a l'air d'être fixé et donc ne pas permettre la décoche ? (j'ai certainement raté le système pour démonter et permettre la phase de tir) Quote Link to comment Share on other sites More sharing options...
brutus Posted March 1, 2010 Share Posted March 1, 2010 Très intéressant !!! Quelle savoir-faire, je suis impressionné. Par contre, ton arc n'a pas une épaisseur dégressive, non ? Quote Link to comment Share on other sites More sharing options...
CHRISTOTOPH Posted March 1, 2010 Author Share Posted March 1, 2010 le verin sert uniquement a determiner la force pour une allonge x , la tension de la corde s effectue avec un levier Quote Link to comment Share on other sites More sharing options...
