I got this in my email the other day and have no idea who did this but what the hell It’s worth a look …

Seems a little short for a concert chanter…
365mm = 14.37"
Does that seem short to you?
The chart is a bit difficult to parse.
Yes, I guess just a little , my D chanters are approx 14.625 or 14 5/8 
as far as the chart being parse, sorry its not my chart. I just got it in an email
Yes, I realize that. I saw these specs last week when they were posted to the Yahoo Amateur Bagpipe Makers discussion group by somebody going as “kilkee01.”
The dimensions David Daye gives for the “Flynn/Quinn” Rowsome-style concert-pitch chanter are even shorter at 362mm / 14.25". I’ve seen measurements for a Froment D at 14-1/16", a Taylor at 14.59", and Bruce Childress gives his concert-pitch chanter length as 14.45".
Where did you get the 14.625" dimension from?
Hi, I’d like to get a look at these plans, but the link won’t work for me (I get an error message) and when I went to the Amateur Bagpipemakers Group I couldn’t find the posting (I checked back to December). Can anyone help me out? Thanks
David
(Not short IMO)
Perhaps the article was removed by request?
Just sign in yahoo amateurbagmakers group go to files and look at Rowsome 1930 D pdf. The measurements of the reamers I made myself and use to make these chanter. The way of working in Exel I learned from Gerard Beau. Thanks Gerard. Instead of measurements of the chanter itself I used 7 different tapers. They sound real haunting.
If someone posted these to me I’d be able to comment. I can’t access that yahoo group, the yahoo site is toxic to my browser.
Thanks chanterdan and Kilkee.
It’ll take awhile for me to digest those measurements for comparison. Nice reamer plan, by the way. Could be tricky to keep the insertion depths straight though!
Aha. This plan seems to be taken from the data for the Hughes/Talty chanter; the measurements were first published by Craig Fischer in the Autumn 1999 edition of Iris na bPiobairi/The Pipers’ Review. The measurements (not shown in the graphic) were taken by John Hughes who now owns the chanter, using drill blanks at 0.1 mm intervals.
The original chanter was 362.5 mm overall, so it looks as though the reamer plan adds 2.5 mm to the bell, and it looks a smidge bigger at the bell as well. That said, I am having trouble interpreting the Reamer 1 data, as far as intended insertion depths.
The Reamer 5 data seems to suffer from an off-by-ten error, I’d make the overall length 345, not 335, to match up with the Hughes/Talty data. Once you make that adjustment, it looks to be a pretty close match for the measurements in most places, The bottom hand bore looks too big to me, around the 11.0 mm point, though. However the similarities are too big to be coincidental, this is surely derived from the Talty data… for instance, subtract 2.5 mm from the tonehole distances and you end up with the Hughes/Talty data
exactly.
This chanter was made of boxwood in “the 1930’s” according to the article in Iris na bPiobairi, “and previously belonged to Martin Talty of Miltown Malbay.” I haven’t tried to reed the chanter in question, and as John isn’t really a concert-pitch kind of guy, I can’t report much on its recent playing characteristics. That said, neither John nor Craig are neophytes so the fact that they chose to publish this data, and that Martin Talty played the chanter for years, suggests that it merits investigation.

Where??? From my plans of course… 
BTW, if anyone is thinking of using this reamer plan, I’d advise consulting the original Craig Fischer article for comparison with the measurements. The reamer plan is pretty unclear about insertion depths and even using a “logical” interpretation of the data in the graphic image, the Reamer 5 and Reamer 1 data don’t seem to match up well with the measurements.
{edited to add}
the top hand bore looks excessively smoothed out to me as well; in the original there is more of a constriction. So overall my impression is that the reamer plan may have removed some significant bore features of the original.
Indeed the reamer I is 53. That is also the total length that goes into the bore. So reamer 1 is marked on 53mm. Reamer 2 on 139mm enz. Reamer 5 should be 346mm. All reamers are made from RVS steel milled on three sides. I put another revised pdf on amateurbagpipemakers group.
Thanks Billh for the remarks. You have seen the flaws. I changed the measurements in the drawing at amateurbagpipemakers.
