Hot Wire Cutting Note

Another note with the hot wire- I could have gotten a better cut quality, however with the higher voltage power supply the wire expanded longer than what my spring could accomidate, so I lost tension. During cutting I had to be pretty careful to get as good of a cut as I did. I need to rework my fixture to allow a longer spring for my next round of cutting. Or, what would work better would be to transition to a fixture that uses two long metal rods to hold the wire, which is what most people use online for large wing core cutting anyway.
