Andy,
I think you should list all safety concerns up front and all the safety tips you have weaved into the work will serve as reinforcement.

> -does the sequence make good sense?

> Anyone with anything to contribute in terms of any knowledge whatsoever

> Note: you do not see safety listed here specifically because I intend on
> weaving notes on it throughout the work. It will definitely be covered.
> Should I add a section devoted specifically to it?

> a) How to hold the file
> i. Basic grips
> ii. Basic strokes
> iii. Twisting
> iv. Angling (direction of stroke and orientation of the tool relative
> to the stroke)
> v. Pressure and pressure bias (how much to use and how to use it in
> affecting very slight adjustments to the cutting action)
> vi. Draw filing (AKA ?Striking?)
>
> b) How to hold the work
> i. Vises
> ii. Jigs and fixtures
> iii. Hands

> c) Aids to precision
>
> i. Square
> ii. Straight edge
> iii. Adjustable bevel
> iv. Radius gages

> vi. Dividers (regular and proportional)
> vii. Compass
> viii. Calipers (inside, outside, hermaphrodite)
> ix. Scriber
> x. Prick punch

> e) Geometry never lies (significance of geometry and using it as a

> f) Filing to a line v. filing to an edge (how to obtain accurate
> results without ending up in a padded cell or ruining the work)
> g) Fundamental filing techniques
> i. Filing a flat surface (establishing rectilinear bounds, hogging,
> smooth filing, and finishing to dimension)
> ii. Filing simple concave surface (singly concave)
> iii. Filing simple convex surface (singly convex)
> iv. Filing complex concave surface (synclast)
> v. Filing multiply-curved convex surface (synclast)
