A friend made me a lazy susan to hold all the "liquids" I keep on my bench - contact cement, Loctites, several viscosities of key oils, penetrating oils, denatured alcohol dispenser, super glue gel, lapping compound, water sprayer, etc, etc, etc. They stay in a small compact place and yet are all easily accessible.
This
is a tone hole gauge to check whether a flute tone hole is flat/level.
Turn the light on, sit the gauge on the tone hole and you can see where
your high and low spots are. This is great for those who push tone holes
up from the bore instead of filing; You can check your progress without
having to take the flute off the dent rod or mandrel. Also great if
you don't like to leave a leak light in a flute while you're working
on the tone holes because of the flute getting warm and your hands sweating.
