Rating Instructions: How to make a Camera Lucida!

At first, the instructions for making a camera lucida looked quite promising and appealing thanks to the drawings, the font and the design in general. After taking a closer look, however, we realized that they are actually quite confusing and not very helpful.
What we first noticed was the missing material and tool list. It was only after carefully reading the instructions that we were able to make our own list. This fact alone takes out the fun of building the camera lucida with theses instructions.
In addition, chronological step-by-step instructions would be a lot easier to understand than writing everything in one paragraph as it is done on the sheet. It is far easier to follow a chronological list than a full text, especially because you want to refer back to the instructions from time to time. Moreover, the instructions are not very detailed, we were fairly confused from time to time.
What we recognized as well was that the drawings do not match the instructions Neither did we know where to start, nor could we make any sense whatsoever of the first drawing.
The firstly believed nice handwriting turned out to be hard to read: We could not decipher whether the figures given were in millimeters, centimeters or even meters.
What confused us the most was the mentioning of David Hockney, what has he to do with all this? Even if he is important in relation to the camera lucida, his name should not be in the instructions.
When analysing the instructions we realized that if we were to build a camera lucida by only using these instructions, we would give up completely frustrated and discouraged. Unless we try to find better instructions on line there will be no camera lucida for us.
