Love the industrial rangehood look - my local fish and chip shop could implement this in a flash.

As a matter of fact I probably could............but I won't.


Oddly enough, (and on a much smaller scale), I've been toying with the idea of fitting a horn to the rear port on my monitors.............silly, I know. Anyways, as soon as I'm able to reclaim my workshop, I've drum shells to be making :-).

out of curiosity ausrock besides having to buy a smock ( which i have sworn for years i am never ever going to do ! )

whats involved in making drum shells , do you laminate several sold pieces and turn them
as in making a clock front or round window frame , or do you find a suitable chunk of log , turn on the bandsaw add bowl saver and just go for it ?

i have a woodfast lathe that gets used more as "knob and handle" maker then something of its quality really ever deserved
maybe one day i will make something "of size" on it just to make it feel loved ... but the last thing i need is a house full of bowls so a snare drum or two makes me curious


got a link i can see?

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 http://www.drumshed.org/forum/ and it's spin off http://www.ghostnote.net/vbforum/ also, there's an active turning section on Australia's own woodworking forum http://www.ubeaut.com.au/ just go to the BBS there.

thank you ausrock , your always helpful.
now i did not say my woodfast sits idle in fact it gets used a fair bit ,
but just knobs and handles for things i tinker about building.

learning to make drums , now that looks like a good way to lose a decade:)

i will be very selective with my brain space before i follow those links,
i can aready see the flashing lights saying
"danger do not go here there rick there is nothing you need to know about there ,
there is already too much you dont know about here , do not press the link "
do not press the link...."
:)
