...some from my research (actualy from web sites of makers, several forums and talking with some makers...) few years ago when I had sweet ilusions of becoming great pipemaker
- indian/ceylon, african, macassar and brown ebony
- european boxwood or castella boxwood/lemonwood
-
cocobolo and some other rosewoods like tulip,
madagaskan, brazilian, indian, sonokeling…
-
some south american woods like palosanto, lignum vitae, snakewood, purpleheart
- native like
plum, pear, apple, olive, laburnum, holly, yew, hawthorn, hazel and even
maple
-
african blackwood, mopane
-
pink ivory could also be used
- less known leadwood, american persimmon,
partridgewood, dogwood,
mountain mahagony
- some australian woods like
red lancewood and few others as well
- some french makers like to use »cormier« which is sorbus and some german makers swiss pear (service wood) which is another from sorbus family
- Dan O'Down used also the
greenheart if I am not mistaken
- some makers today use manmade materials like
delrin, ebonite ect.
The one with bold text has been already used for Uilleann pipes as far as I know (at least the chanters), the others were used for other types of bagpipes or experimentation
...so, many woods can be used if they are dense and hard enought. I hope it helps, Best, AA
