Re: Mainstock ferrule and cup taper

Thanks Geoff

Let me just say that it's very encouraging hearing from all three of you

Re: Bore Profile Distribution into Multiple Reamers

With this Coyne based concept of scaling where the throat sizes increase with pitch(not sure to what extent this applies to the works of other 19th c. makers) would this throat size difference affect the volume of the chanter? If so, should drone bores be enlarged or decreased with the chanter throa...

Re: Mainstock ferrule and cup taper

Alright. So the slight change in wall thickness may actually help to produce a steady hum rather than distinct ticking.

Thanks

Re: Mainstock ferrule and cup taper

Thanks for such detailed explanations.

One other thing: When making a tapered hollow mainstock would it be best to use a boring bar to cut a tapered bore on the inside, in order to keep a uniform wall thickness, or is this unnecessary and a parallel bore could be used?

Re: Mainstock ferrule and cup taper

On a related note, when bass regulator bars are curved slightly to splay out nicely, especially when fit to a tapered stock, how does this work with the wooden insert inside the metal tube? Geoff Wooff briefly touched on this in the video where he talks about his Harrington set but I'm still not exa...

Re: Uilleann Reamer making issues

what sort of section/shape did the steel initialy have? As he's making a D reamer, it would have started as a tapered rod, turned on a lathe. Then he grinds off just less than half the material with the pictured grinding set up to create a D cross section, which will make a scraping cut well suited...

Mainstock ferrule and cup taper

I'm looking into rolling ferrules from sheet and am wondering about the mainstock cup and ferrule. On some 19th century examples it appears, though it's quite hard to be sure, that the ferrule is tapered just like the drone slides. On the other hand, I really can't find decent enough pictures or dat...

What types of wood would that be?

Re: Bore Profile Distribution into Multiple Reamers

Thanks Bill

The throat of the c chanter appears to angle in more than the others just below the throat, and the throat also seems closer in diameter to the C sharp than the b. Do you think this is the way it was intended, maybe made with a different throat reamer?

Re: Bore Profile Distribution into Multiple Reamers

Actually, the C and C sharp chanters shown on the tone hole placement graph in the lecture seem to both have throats of about 3.9 mm. Does this mean that a Bb chanter of the same design parameters might have a throat that's the same size as the B, which is 3.7? Interestingly enough, the Coyne narrow...

Re: Bore Profile Distribution into Multiple Reamers

This graph section shows the throat areas of the Hannan, in blue(dark is min, light is max) and O'Hannigan(red) chanters: throats.png The area indicated by the green arrow is the main area of the two bores which is in disagreement, disregarding the differently shaped lower sections. Surely this was ...

Re: Bore Profile Distribution into Multiple Reamers

Also, do you have any ideas about the more inwardly curved, smaller bell of the O'Hannigan chanter?

Re: Bore Profile Distribution into Multiple Reamers

Do you think it's true that a straight bass drone slide would require a different standing section than a slide of the curved type with or without a puck? I believe something to that effect was stated in the Sean Reid Society article about the Harrington body. Are drone pitches ever scaled by manipu...

Re: Bore Profile Distribution into Multiple Reamers

Thanks for all the info Bill, I suppose I have a bit more graphing to do! If the throats of sharper pitched instruments are larger than the throats of their lower pitched counterparts, does this mean that their tone holes will also have to be larger? Regarding the drones, do you think that the drone...

Re: Elder reeds prior to the 20th century

Maybe the pipe makers would have had cane available to them since they mostly worked in centers of commerce, but the pipers in the countryside making their own reeds would have had to use elder.
