DIMENSIONS FOR MY HARDIE PIPES
(to accompany PVC bagpipe article)
PLEASE NOTE -- I am a bit hesitant to provide the following
information as it is MUCH better to borrow a set of real pipes and
take the measurements directly yourself, but I have had very many
requests for dimensions & offer the following in answer to these
requests. With an instrument of this type, the keyword is
experimentation! If something does not work or sound right, diddle
& alter it's dimensions a bit.
-------------------------------------------------------------------
NUMBERS = outside diameters
lower case letters = inside diameters
UPPER CASE LETTERS = length of particular section

TENOR DRONES (SAME MEASUREMENTS FOR BOTH TENOR DRONES)
INSIDE DIAMETERS:
a- 7/16
b- 11/16 by 4" long
c- 3/8
d- 11/16 by 3 7/8" long
e&g- 9/32 (same diameter entire length, with slight end
flaring for reed)
h- 7/16
i- 5/8
k&m- 9/32 (same diameter entire length, with slight end
flaring foor reed)
bell- rather "chalice shaped" inside, 1 1/8" maximum diameter
SECTION LENGTHS:
F- 1"
G- 3 7/8
H- 2 3/16
I- 2 7/8
J- Total length of this section is 5"
L- 1 1/8
M- 1"
N- 6 5/16
O- 4 3/8
P- 3 9/16
Q- 3 5/8
R- 4 5/16
S- 3 1/2
T- Total length of this section is 6 13/16
V- 1 7/32
OUTSIDE DIAMETERS (Note that these are not at all critical)
1- 11/16
2- 7/8
3- 1 5/16
4- 5/8
5- 7/8
6- 1 5/16
7- 5/8
8- Tapers; 1" on each end & 7/8 in middle
10- 3/4
11- 1 5/8
12- 7/8
13- 1 5/16
14- 9/16
15- Tapers; 7/8" on each end & 13/16 in middle
17- 11/16
DIMENSIONS OF DRONE STOCKS:
Bass Drone - Tapering; 1 5/16 at bag end to 1 1/2 (outer diameter)
27/32 non-tapering inner diameter
Total length is 7"
Tenor Drones - Tapering; 1 3/8 at bag end to 1 5/16 (outer diam.)
(both the 25/32 non-tapering inner bore
same) Total length is 5 1/2"

DISTANCES TO THIS LINE-------------------------->|
Overall chanter length is 14 5/16" (left end to right end of
diagram above)
Overall taper of chanter inner bore is 27/32 at big end to 5/32 at
other end - linear taper.
Overall dimension of chanter outside bore is 15/16 at big end
to 1/2 at other end - linear taper.
Two 3/8" diameter "air/sound holes" (not fingered) are drilled
opposite each other 2 5/8" from big end of chanter, & on sides (not
in line with finger holes)
"knob" just behind "plug-in" is 1 5/16 max diameter.
"plug-in" is 11/16 diameter by 15/16 long. This is where the
chanter plugs into the chanter-stock.
Thumb hole is obviously on the opposite side of fingerholes.
-------------------------------------------------------------------
I'm afraid that's about all the information I can provide. There
are sources on the internet of various pipemaking info - even some
including dimensions. I will try to find some of these sites &
provide a link here. In the meantime, if anyone does locate such a
site, please tell me.
