Tagged: Oboe Hardness Tester
I am thinking about purchasing one for my reed making. Does anyone have any experience with this? If so, what numbers are you striving for? and Do you measure the pre-gouged piece of cane or gouged piece of cane? Any information is much appreciated!
Thanks in advance!
I have used the Reeds n Stuff digital hardness tester personally and in my business, Supérieure Cane Processing, for several years and find it to be precise and an objective/consistent method to judge cane quality. I test pregouged cane (Reeds n Stuff pregouging machine) at about 0.80 to 1.00mm thickness (dried cane) and try to target a hardness reading of 0.10 to 0.12 (hard) … final gouge is 0.57-0.58 (final shape I use is RDG 1) and select/premium cane tubes from the French areas of Cogolin/Grimaud, Saint-Tropez, Bormes-les-Mimosas/Le Lavandon.
General hardness guide: Extremely hard* = 0.05-0.07; Very hard* = 0.08-0.09; Hard = 0.10-0.12; Medium = 0.13-0.16 (good flexibility & stability … some consider to be the professional standard); Soft = 0.17-0.20 (lighter in character & good for student reeds).
* Very dense/hard cane typically needs to be gouged thinner by .02 to .04mm than standard (ie .oboe: 0.56-0.58mm for hard vs 0.58-0.60mm for medium/medium hard oboe cane).
I have just been debating about if it is worth the money especially when trying to make my results more consistent. Thank you for all your information Don!
