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 1 2 3 4 5 6 7 8 9 10 |~~~\______/~~~~~~|____|~\______/~~~~~~|____|~\___________/~|___ |bell a b |__c_| c d |__e_| e | g| |___/~~~~~~\______| |_/~~~~~~\______| |_/~~~~~~~~~~~\_|~~~ ^ M^ N ^ O ^ P ^ Q ^ R ^ S ^ T ^ V^ BASS DRONE 11 12 13 14 15 16 17 |~~~\______/~~~~~~|____|~\___________/~|___ |bell h i |__k_| k | m| |___/~~~~~~\______| |_/~~~~~~~~~~~\_|~~~ ^ F^ G ^ H ^ I ^ J ^ L^ 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" ------------------------------------------------------------------- CHANTER DIMENSIONS (Taper is NOT shown here) HOLE DIAMETERS || 5/16 5/16 9/32 3/16 ||______________________________________________________/~~~| | 5/16 9/32 15/64 3/16 '-----, | o o o o o o o (o)thumb | | 8 5/16 6 1/4 4 1/4 2 5/8 ,-----' ||~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\___| | || 9 9/16 7 5/32 5 1/4 3 1/4 | 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. Thanks Dennis Havlena - W8MI, northern Michiganclick here to access my homepage
