Two skinny J's
Sadly I don't know I found out very quickly in my small shop, even with all the air filtration I have and dust collection, if i don't wear a respirator I'm coughing and chocking pretty quickly. Walnut scares me anywayBet that smells nice when you’re working it.
The allelopathic chemical from black walnuts is called juglone. Many people have allergic reactions to the juglone present in pollen from black walnut trees. Woodworkers who breathe sawdust from black walnut can get a runny nose or have asthmatic reactions.
