Using arduino IDE 64-bit on ubuntu 12.04 - Guide to Arduino make sure you open arduino as power user! Otherwise the serial port will be greyed out.

• Research for choosing between rod, dovetail, or boxed way for linear guide (whoa there's V-ways and half-round ways too!) Gah I need a free download of the book "Foundations of Mechanical Accuracy"

Dovetail

You are not under the impression that the dovetail cutter needs to be the full width of the female dovetail are you?The cutter only needs to be as tall as the dovetail.Your remark about not having large dovetail cutters prompts my question.

Dovetails only need 1 gib

Actually the dovetail is the simpler mechanism. It is simpler to make and simpler to adjust in use. The one gib at 45 or 60 degrees takes up slack both sideways and vertically. One adjustment and you are done.

I was afraid of the results before I made my first dovetail, but it is a piece of cake if you plan it properly. The setup is the same for both male and female parts. As mentioned above, you do not use a cutter that is the full width of the female dovetail. You use a standard milling cutter to rough out the center, usually to a depth slightly greater than the actual dovetail. then you cut each side individually. The cutter only needs to be tall enough to cut the whole angle at one time.

I used a CAD drawing and placed even sized circles tangent to both the angled sides and the flat top/bottom surfaces to give me a way of measuring the width of the dovetail. You can read the distance between them off the drawing to three or four places and them use drills or ground, round stock of the same size to measure your work. Just mike between them on the female dovetail and across them on the male. Real quick way of checking your work on the mill. Of course, with a gib, you don't need extreme accuracy.

Box

Boxed way more rigid than dovetail

Boxed way conventionally steel with turcite for anti-friction contact surface OR cast iron with oiling OR metal with high-pressure oil (hydrostatic)

Boxed way conventionally ground then scraped
