I built a ship in a bottle and used this pin vice drill to drill holes in an actual toothpick for part of it. Now I'm hand drilling holes in the hull. Yes, subs have a surprising amount of holes and vents in their outer hull. Not bad that 

I'm getting so much use out of an $8 tool. http://www.amazon.com/gp/product/B001DZE5BQ/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

I like to rubberband the hulls together. One half is really floppy because of the huge cutaway. Test fitting like this can let the plastic naturally sort of bend together and form fit before gluing-also it makes working and drilling easier with this stiffer object.

Holes!
