Since the majority of pipes are made of stems that were pre-formed, I think it is safe to say that stems were largely an afterthought for most pipes. I suspect that when most folks think of pipe making, they think of stummel shaping and stem fitting. I do not think it even crosses the mind of the majority of hobbyist pipe makers to actually hand cut stems. I am of the opinion that this is an unfortunate mistake. The stem, both functionally and aesthetically, is a huge part of the success of a pipe. Here's why:
1. Most flow problems in a pipe are in the stem. If you have ever had a wet smoker that whistled when you drew through the pipe when empty, I can almost guarantee you the whistle and wetness were caused by the stem. Lack of care in the stem is the demise of many pipes.
2. The comfort of the stem in one's mouth can have a major influence on whether or not it becomes a favorite of the smoker.
3. Because of the variations on shape, size and proportion of stummels are infinite, but the economical feasibility of manufacturing pre-formed stems requires a very limited number of shapes and sizes, using pre-formed stems requires compromises on pipe design. By contrast, stems made expressly to complete the design of a singular pipe offers the opportunity for the most aesthetically pleasing pipe.
4. Vulcanite is commonly considered the most comfortable stem material in the teeth. Its main drawback is that it oxidizes and therefore requires maintenance; however, the high-grade German vulcanite typically used for hand cut stems is a MUCH superior material to the vulcanite used for pre-formed stems. As such, the German vulcanite used for hand cut stems oxidizes so little that it requires little more care than the bowl of the pipe, while retaining its comfort advantage over acrylic.
All that said, I do offer some pointers on using pre-formed stems because I recognize the economic necessity of needing to start pipe making with compromises. Since we cannot buy pre-formed stummels, and start pipe making by fitting hand cut bits to pre-formed stummels, we opt for the choice to make stummels and fit pre-formed stems. It is a fine place to start, and thanks to the Pimo tenon turning tool, a relatively inexpensive place to start.

Delrin[http://en.wikipedia.org/wiki/Delrin] is the brand name for an acetal resin engineering plastic invented and sold by DuPont. Often marketed and used as a metal substitute, Delrin is a lightweight, low-friction, and wear-resistant plastic capable of operating in temperatures in excess of 90 degrees celsius (approx 200 degrees Fahrenheit). According to the material safety data sheet from DuPont, the material has a slight odor of formaldehyde.
