If the helix begins to warp or distort, examine the string rigidity. Alter the strain evenly alongside all the helix. Moreover, be certain that the strings are securely tied and never slipping.
6. Uneven Spacing
Attempt for even spacing between the twists and turns of the helix. If the spacing turns into uneven, gently regulate the positions of the strings to revive consistency.
7. Incomplete Helix
If you’d like an entire helix, be certain that you proceed the twisting and crossing course of till the specified size is achieved. Don’t cease prematurely or the helix might be incomplete.
8. Unfastened or Untightened Strings
Be certain that the strings are tied tightly and securely on the ends. Unfastened strings may end up in a wobbly or unstable helix.
9. String Stress
The stress of the strings performs an important function within the integrity of the helix. If the strings are too unfastened, the helix might be weak and flimsy. If they’re too tight, the strings could snap. The best rigidity is average, permitting for flexibility but sustaining structural stability. Experiment with completely different rigidity ranges till you discover the optimum steadiness.
