I must make a very smooth, cosmetically impeccible brass tube that tapers
uniformly from 1" i.d. to 5/8" i.d. over a length of about 16". Lack of a
visible seam would be a plus.

It must be bent in three non-planar curves, none exceeding 45 degrees of
bend.

Anybody got any favorite methods?

Never tried this, but it sounds lie a job for metal spinning. Make a mandrel
with the proper taper on a live lathe tailpiece and feed it into the brass
tube on the chuck. Use spinning tools to work the tube down to the mandrel.

The bending could be done afterwards with a jig and sand filling the tube to
prevent kinking.

Does it have to be brass?

If you could use steel instead you could hydro-form it a bit easier,
just like the pipes on a 2 stroke.

You might be able to do that with brass, but I'm not sure you could hide
the seam as well. How about making the seams a decorative item? Form the
two halves, then trim the flanges down, and silver solder a decorative
strip down them?

Does the taper need to be full length? If not, scrounge a male and female
of whatever Morse taper (or whatever taper you can find) covers your ID
range and use it as a swaging punch and die on the inlet end of your tube to
make a taper 3-6" long (annealing as needed), then like others said pack
with sand and bend.

I can make the tube the correct taper out of a single sheet of metal,

After bending, coarse-sand the outside, then fill defects, sand smooth,

Do you mean electro-less seeding of the carbon fiber finish, then plating,

If I plated the metal, I'd have to do something with the seam (like they
show on that trombone vid) to flatten it.

Bending isn't the issue. I have a bender that can be pressed into use for
this purpose.

The issue is all the mandrels, seam rollers, and other smoothing devices
necessary to get the tube 'clean' before bending.

I saw somewhere that the material in the tube during bending is NOT just
water-ice, but a mixture that freezes hard (like would, say, ice cream),
but does not form a brittle crystal like water-ice does.

I'll have to look that up before Monday.

The tube is 1" i.d. at the mouth, and 5/8" i.d. at the small end, over
16", with three sub-45-degree non-planar bends.

It's an _almost_ trivial project, except that I want it to look sexy and
slick, because the rest of the machine is beginning to approach 'steam
punk pretty', and I don't want to add ugly parts to it.

Three or four parallel seams might not look as out of place as a

I had a thought about hte fiberglass/carbon idea, Lloyd.

Is there, or might there possibly be, a possible danger with static
electricity?

If so, metal would be better choice than any plastic, including a carbon
lay-up. The carbon fiber fabric would be encased in resin, which would
insulate the carbon fiber and possibly result in a static charge buildup
due to the paper sliding through the guide.

Metal work. Good stuff...

Make a brass "funnel" ("first - catch a rabbit")

Fill it with sand and start wrapping it round a mandrel / post.
Ideally, one mid sized to the curve you want and the tube you have.

Geeze, you guys spend more time spitballing than it takes to do it.

LLoyd you have two problems. Bending is the easy one. The taper is something
else.
Because of its long length and small diameter it will be a bitch. I can
write a thousand words on how to do it with a tapered strip of brass, a
rawhide hammer and a beakhorn stake, but it will still be a bitch.

Rethink the taper. Make a short taper and attach it to a 5/8 straight brass
tube.
Myself I would saw the rim off of a .50 cal cartridge, silver braze a piece
of 5/8 brass tube over the neck and turn a fitting to attach the big end to
the 1" .

To bend, fill the tube with lead (first paint the interior with milk of
magnesia and let it dry, it will keep the lead from sticking). Use wooden
dies for your bender. Carve matching grooves in them. And be prepared to
bend more than one before you get it right.

The finish is now easily solved. Make the tube of brass, with just a lap

As long as you know how to sodder.

I learned to "sodder" long before I learned any other metalworking

I am just having a giggle at the propensity of Americans to leave out
