Just a few calculations of rope lengths. Let's see: Golden rope (the one for rungs, 6 mm in diameter) You need 1.8 meter for every rung and 3 rungs for every 1 meter of ladder, plus 1 bottom rung. So: 7 meter ladder = 7 x 3 rungs + 1 rung = 22 rungs = 22 x 1.8 meters of rope = 39.6 meters of rope Allow yourself some reserve for tying knots and burning ends. 41 meters should be enough. Blue rope (the one for main strings, 7 mm in diameter) You need two times height of ladder plus knots plus top eye plus bottom tails: 7 meter ladder = (2 x 7) + (22 x 2 x 0.1) + (1.5) + (2 x 1) meters of rope = 21.9 meters of rope Again, having some reserve is recommended, 24 meters is fine. Step 4: Rungs Step 5: Right Side Step 6: Eye Step 7: Left Side |
