I guess we are right back to sanding vs planing and scraping. I gave up ebony because it was increasingly causing me irritation. It never bothered me for the 30 odd years previous. Fortunately bog Oak came to the rescue and I have absolutely zero problems with that or any other European hardwood for that matter (at least the ones that I've tried). Unfortunately good old oak is rare in terms of guitar woods. I also strongly suspect that maple is low on your chart, a wood that is much more commonly used for musical instruments. Poor old cherry rarely gets a look in although it can look very beautiful especially if a reddish colour and with figure. Don't know where walnut features on your chart but it doesn't seem to irritate me.amezcua wrote: ↑Mon Jan 08, 2018 9:25 amSurprisingly the list of woods for making guitars shows even an innocent sounding wood like Elm is on a danger list . That`s danger from dust . The word "common "in the list refers to how common the bad effects have been . One of the safest woods where the word "rare" appears is good old fashioned Oak and oak is a nice sounding resonant wood . It`s certainly not a rare wood in the normal sense . The chart I saw mentions the word Sensitisation for several woods . A few dust types will attack the central nervous system and at least two will give you a Cardiac . Time to check your air cleaner systems . Sweeping brushes are now recognised as the most dangerous pieces of equipment in a workshop . Sensitisation can lead to itching and rashes on the back of hands and forearms , eyelids , face , back of neck and (wait for it ) genitals . Now wash your hands .
