6. Uneven Spacing
Attempt for even spacing between the twists and turns of the helix. If the spacing turns into uneven, gently alter the positions of the strings to revive consistency.
7. Incomplete Helix
If you would like a whole helix, be sure that you proceed the twisting and crossing course of till the specified size is achieved. Don’t cease prematurely or the helix shall be incomplete.
8. Unfastened or Untightened Strings
Be sure that the strings are tied tightly and securely on the ends. Unfastened strings may end up in a wobbly or unstable helix.
9. String Pressure
The stress of the strings performs an important position within the integrity of the helix. If the strings are too free, the helix shall be weak and flimsy. If they’re too tight, the strings might snap. The perfect pressure is average, permitting for flexibility but sustaining structural stability. Experiment with completely different pressure ranges till you discover the optimum stability.
