According to :
regardless of the shape internally , you could machine this part on a lathe
, with little trouble , the internal taper is a little tricky but not really

Not sure what an internal taper is, but it's good to hear that it isn't
that difficult.

what is it worth /

It really depends on the success I have -- the instrument I'm making
(an irish whistle) is broken into two parts, the body (which this is a
part of) is relatively simple -- that tapered piece with an 8" length
of tubing with specific sized holes drilled into it. That's the easy
and relatively inexensive part. The harder part, the mouth piece,
has a much more complex shape and requires me to bore out some delrin
and lathe a plug with a windway cut into it.

It sounds as though you are planning to go into competition with
Copeland, who makes the nicest tin whistles that I have ever tried.

how many do you need?

I'd prolly try to get 25 or so to start with for my first run.

have you tried getting prices from machine shops?

No, but that's another good idea! Being primarily a progammer, I have
no clue where machine shops are around my area (Delaware), so I may
have to look around.

Hmm ... as a programmer, this opens the possibility of using a
CNC lathe to produce your parts. (Though it really helps to have
experience with machining before you start with CNC, just so you know
what works and what doesn't.

Enjoy,
