Portland’s scarlet star studios are home to Gretchin Lair & Sven Bonnichsen and are visited by a range of other creative types and artists. Sven is a machinist and animator and makes his own armatures, puppets and sets.
As a lot of the work involved in making armatures is drilling and tapping, he’s also been making his own tools such as a tap holder.
Sven’s got some excellent stop motion advice if you are making your own stop motion film and here’s some links to some of his articles on machining.
Here’s also a series of articles on building an armature for animation which looks at techniques for working with small components, soldering, marking out and drilling.
