| === Airflow ===
| |
| Many pipe enthusiasts are familiar with Rick Newcombe's writing on airflow, where he suggests that pipes with an open air flow smoke better. While not the originator of this concept, he has been its most public advocate, and duly credited with its popularization. Ken Campbell has written an article for The Pipe Collector called [[Airflow: The Key to Smoking Pleasure]] which further explores the concept.

| The concept of "opening" was originally employed in the after-market modification of production engineering. Many pipe makers have adopted elements of this concept of airflow, with many American makers using airways ranging from 9/64" to 11/64". A related and perhaps more important aspect of an open air flow is providing for constant airway volume as it passes through the sections of the pipe. This concept was pioneered by [[J.T. Cooke]] and further developed by [[Trever Talbert]], [[Jody Davis (J. Davis)]] and [[Todd Johnson]]. While traditional pipe engineering often utilizes different diameter bits for airways in the shank and stem, this constant volume technique employs the same overall diameter bit throughout, with the exception of the last 1" or so at the bit. Here it tapers evenly down while also widening out. This provides for a comfortably thin bit, while also providing for a constant volume of smoke throughout the smoke stream.
