my dear Alan - here on this site in the link bellow you will find a lot of "how to's"
Pipemakers Forum
most of my "knowledge" related pipemaking comes from that and some other forums...
...
the pipe was cut in rough shape using a regular hand saw.. After that i used a french wheel to sand it into a more acceptable shape and after this step i used dremel rotary tool for fine things... when i was happy with the shape, than i used sandpaper and hand sanded everything down to get the fine, smooth surface... so sandpapers were 320, 500, 800, 1200 (if you are using briar you can also go with 2000 too)... from the step 500 up to the end on every step before going to a finer sandpaper i used polishing wheel and brown tripoli to smooth the surface better and to allow me better to see where the pit's are...
after sanding and olishing is done, i used carnauba wax and sewn cotton wheel from Pimo supplier to finish the pipe... that is how you get the surface to look like that...
also, you never go to a finer sandpaper gradation before you removed every pit you have from the previous papers (you probably know that rule as a woodworker)...
...
the mouthpiece was made out of a acrylic rod 25x30mm in crosssection... i have sanded it down to get a rough cirlular shape in crossection and than used a handmade lathe for turning wood... it is not very precise but good enough to turn a rough shape. after that, i used hands to sand the mouthpiece and finish it... sanding was the same as with the wood except i used a finer muslim polishing wheel after using brown tripoli and cotton polishing wheel... clean finer wheel is necesary in order to get the mouthpiece so shinny...
...
the process is more complex than this above - this is only a rough theory how to do it
if more info is needed, i am here
