Hi. It was more tedious than tense. I cut down to just expose color and finished in the dark using an internal light to even things out and remove traces of other layers/color. Really takes a toll on the peepers and takes a while to get used to following the silhouette of the tool as opposed to seeing it clearly.
Did you use a wand light/ flexible light to do the internal lighting while working on it ? I understand the toll /tired eyes part very well...... all toooooo well lol!! thank you for that incite into your technique
I use a flex head led light to ensure all remnants of the lining are removed but found it doesn't work well for general illuminating, the beam is too focused.
I modified a $8 'bunny' led flashlight by cutting the led loose and running about 12" of wiring for the 'flex lead' and mounted the led (shallow mount to allow for max dispersion of light) into a suction cup (cup came with a clip for hanging things, bored it out). The cup gets attached to the egg with some flexible foam medical tape which conforms well and pulls off cleanly.
