Round 6 #3 Prior UD experience.
The UD ceramic tweezers are very handy for coil building. I built an 8 coil twisted wire coil (UD twisted wire), needed to compress it. The ceramic tweezers let me do this while firing (at about 10W, without wick of course), when the wire is most malleable. The ceramic tweezers let me do this, so I now have a nicely packed coil.
(ONLY use ceramic tweezers for this kind of thing.)
