This is a set of four booklets by Robert Porter about making tiny drills; a micro drill press; drilling attachments; and information about taps, drills and dies for the clock and watch maker.

The title are: How to Make Tiny Drills Quickly, Easily, & Accurately; How To Make A Super Sensitive Micro Drill Press; How to Make a Pivot Polisher and Micro Drilling Attachment for the Small Lathe; Taps, Drills, & Dies, Inch & Metric: Useful Information for the Watch/Clock Maker and Model Maker.

How to Make Tiny Drills Quickly, Easily, & Accurately:

This guide presents a simple method to make a type of drill that is useful to the jeweler, watch and clockmaker, instrument maker, and others for repivoting work, prototyping, and many other applications where a small drill is needed.

How To Make A Super Sensitive Micro Drill Press:

This is a reference book intended for those who enjoy the hobby of clock & watch repair.

This simple and easy-to-make little drill press is designed to drill holes in the .004" to .032" (.1 to .8 mm) range, and also solves two problems common to drilling very small holes - namely, that an ordinary drill press is not sensitive enough for the operator to "feel" the cutting action of the drill. And, that the small drill does not turn fast enough to be as effective as it could be.

This drill press is very sensitive, and spins the drill in a range from 12,000 to 30,000 rpm with the recommended power supply. We also show how to make the micro drills, and how to make sure the spindle and drill are as concentric and axially aligned as we can make them. "X" and "Y" slides also provide a means to accurately position the work for drilling.

Although this micro drill press is designed with the watch and clock maker, model maker, or other highly skilled artisans needing a way to drill small holes in mind, it can easily be scaled up for larger work. Component sources are also listed.

You can make this little gem with a couple of pieces of aluminum bar stock from a hardware store, some 4-40 screws, and a few other off-the-shelf components.

How to Make a Pivot Polisher and Micro Drilling Attachment for the Small Lathe:

This 24 page how-to guide is packed with over 30 pictures and several line drawings to show you how to make a simple, but effective, polishing and micro-drilling attachment for your lathe. You are also shown how to make the laps and small drills. Polishing pivots reduces friction.

Slide rest mounted pivot polishers are difficult to find, and are expensive when you can find them. This simple and easy to make attachment offers the watch/clock maker, model maker, and other skilled artisans a way to grind and polish pivots; as well as a means to drill work in the small lathe. Polishing pivots reduces friction and increases the efficiency of a watch or clock gear train.

Taps, Drills, & Dies, Inch & Metric: Useful Information for the Watch/Clock Maker and Model Maker:

This guide contains over 65 pictures and many line drawings to show you just about everything the watch/clock maker, model maker, and hobbyist needs to know about inch and metric taps, drills, & dies to complete a project. You are shown step-by-step how to make your own custom-sized drills, how to make a special tap, and how to make a bushing and screw to repair a chronograph watch. Adjustable dies are explained as well.

A comprehensive list of drill sizes, as well as quick-reference inch and metric thread charts with suggested tap drill sizes, and other useful information about watch stem and crown threads, pocket watch pendant taps, and much more is included in this handy bench book.
