I'll refrain from commenting on a Woodfast sitting idle...........only because my Teknatool Nova is doing the same thing at the moment :-)
There's probably five "main" methods of shell "making"...........:
1)Solid shell..........often considered the "ultimate", turned from a suitably chosen and cured "chunk of log".
2)Steambent.........again, often considered the "ultimate" as it involves old craftsman skills.
3)Stave (think beer keg)
\
both methods involve traditional woodturning technigues.
/
4)Segmented (think brick wall)
5)Ply..........the most common and used by the vast majority on manufacturers.
The first four all require turning at one stage or another but most people use a larger metal lathe with it's automatic feed, etc., which means they don't have to learn true woodturning skills, they just clamp the tool in place, set everything up and hit the "go" button :-). The easiest to make is a stave shell followed by a basic segmented shell and some more ingenious guys have made jigs which allow them to use a router for the shaping. A solid shell isn't "technically" difficult BUT it does require careful timber selection and a bloody long curing and turning process. Steambending is another story all together..........I did it many years ago for boats and although I have a steambox, it isn't overly high on my "to do" list just yet. I'm focusing on ply (snare) shells, mainly using Aust., timbers but because of what I've put into learning and developing my methods, details are only for private communications, also, it's probably the most labour intensive and potentially difficult method.
Two drum making forums are
