Looking for a tube/kinda funnel
Hello,
I'm looking for a pipe/funnel (or any other plastic/glass container that can be easily adapted to that shape) like in the following drawing:
![](http://i60.tinypic.com/2jbs021.gif)
(lateral view on top, bottom view on bottom)
it should be open and circular in both ends,
the larger end should be flat,
and the smaller internal diameter should be at least 0.9 inches (about 23mm).
I don't know what to look for, so any idea is appreciated ![:)](./images/smilies/smile.gif)
Thank you and sorry for the odd question.

They're called "thistle tubes".

Rapopart’s Rules for critical commentary:
1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it
that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.
Anatol Rapoport was a Russian-born American mathematical psychologist (1911-2007).

That was a good call, thank you! ![:)](./images/smilies/smile.gif)
I think it'd be difficult to find one shape more like my drawing because I'd need surface at the bottom and larger smaller end to fit another tube in
it (of about 0.8" diameter).
Thanks again

When I saw the drawing I immediately thought of this:

Right (it's already written in the title) but I'd need something closer to my drawing and with less interal volume at the bottom (thus not conical).
Thank you

Have you checked with this person:

It's a simple piece that I could almost make by hand, even with my poor skills, but any glassblower with a lathe could do it easily.

If you really want to do it yourself (It won't be expensive if thglassguy does it for you), just use a thick glass tube in a drill,
using a graphite battery rod or wet dowel as a shaping tool. Flare it out while heating. I flared out the ends of several 5mm tubes like this, which I
use as thermocouple wells.
Fear is what you get when caution wasn't enough.

Looks like a valve from a my old straight 6 Dodge...
Also looks like a glass frit funnel bottom, that is the closest thing I have seen to that.
