Do you know the secret handshake? If they told you they would have to break all your reeds! In short, I haven't a clue either. ![[grin]](http://test.woodwind.org/clarinet/BBoard/smileys/smilie5.gif)

One looks to be a post drilling jig. Also one looks to be a barrel reamer. I think the smaller tools are for the lathe. I can't make out the cylindrical forms, perhaps hard rubber for socket grafts.

Yeah, I believe with some determination, a stout pocket knife and a nice chunk of dogwood someone could make a nice little clarinet with those tools. Sure. Why not? Let's go for it....
I think you're correct about the drill jig, John. And the round things, ummm, something for fitting the jig to different size posts? Or - not? Naw - it looks to big for that. The lower objects look to me like pivot reamers, maybe, and one could be a tube shortener... or maybe sumthin' else.
My, oh me, but we are good guessers tonight... 
Somehow, just me I guess, but I don't have the gumption anymore to write to sellers about stuff like that.

I am curious to know the best kind of tools and machinery actually used to mfgr a quality clarinet. Is there a web site or other info available that describes a manufacturing process, tooling setup and design drawings that anyone may know of to mfgr quality clarinets?

These are the "Wouff-Houng" and "Rettysnitch" of clarinet making.

Thank you all. After viewing the sites it seems the commercial clarinets are made on a CNC and the Chardash are made on a lathe and milling machine. Im curious as to how they hold the undercut tone hole cutting tool inside the bore in order to do the undercutting from the inside! Judging from the direction of the tone hole cutting tool angle the tool shank would have to be attached after inserting the angled cutter into the bore. A tedious task I would think and with four differant size holes they probably have to use four differant size cutting tools with varied angles. The photos of the tool used clarified to me how my clarinet was undercut. I would like to tour one of the mfg facilities. Very interesting. Thank you. ATV

You may be able to arrange a tour with a small group, Avumba. If you know a couple of band directors who would be interested, or maybe some who have already made arrangements, you might get in that way with them. It's my understanding that they don't give individual tours. That's what I was told a few years ago when I stopped by (a factory in Indiana) for some other information. Another way you could get in (they also told me) might be to apply for a job. That way you could get a real good close up and personal look at just how mundane and boring some of the work really is
I believe there are still some cottage industry type instrument makers in Europe who turn out a few or a few dozen clarinets a year. That might be more in line with what you have in mind but possibly more expensive for you, depending on where you live now. Perhaps some of our friends there could lend a little information about that possibility.
As you can see from the above links, there are many approaches to the instrument making process.

Undercut burrs are passed on a carrier into the bore to the appropriate hole then seized by the shaft of the drill-like tool and pulled upwards to fit and cut the underside of the tone hole.
Now, can someone pleez tell me where I can demo some nice instruments when I visit New Orleans?

What intrigues me is the bodies with the INTEGRAL raised tone holes.
Just how do they carve away all excess timber around the tone holes to get such a perfect cylinder. Lathe turning is out of the question because that would remove the raised tone holes.
I guess a CNC machine, could neatly work around the raised parts, but how does Chadash do it, with his apparently relatively primitive equipment? Would he lathe parts between the tone holes, and then finish the rest by hand? That would be extremely tedious!
I notice the photos neatly avoided covering this process.

I noticed that too, regarding removed wood around the chimneys, Gordon. It's one of those things I always wondered about but didn't know who to ask.

Good question Gordon. I cant figure out how the raised tone holes can be machined before or after the outside bore is turned to size even on a CNC. It certainly looks like all one piece but is it!

My mistake Bobd but, I think you get the drift.

"It certainly looks like all one piece but is it!"
Probably. This is pretty standard for many pro instruments, and I think it has been around for longer than CNC machines.
Somebody must be able to disclose this trade secret.
Ken knows these sorts of mysteries of life. Ken?
