## Ellipses and Another Curve

All of the references give a method of drawing an ellipse using the two foci and some string. I have found this method suitable only for drawing jelly bean or kidney shapes.

## Determining the Counter-Rake for Work That Lies Athwart the Plane of the Rake

The thingy you’ve got to build lies diagonally across a raked deck. How do you figure out the length, angle and bevel so that it sits vertically?

## Compound Rake

Where the rake is the combination of two angles the actual slope of the rake is a transcendent trigonometric function of those two angles. I ran off with the theater to avoid having to deal with algebra; and Trig is Algy’s bigger, meaner older brother.

## The Stovepipe Problem

What are the dimensions of the opening required to pass a cylindrical object through an inclined plane?

## Cumbersome Division

What do you do when you have to equally divide a line with an awkward (39-5/16”) or unknown length into a difficult number of parts (7)?

## GEOMETRY

I’ve been tossing around terms like; erect a perpendicular, strike an arc; geometry. Unlike what you may have thought in Middle School; Geometry is your friend.
