I was using a mask and I still had trouble. I used the mask and a little wind to help finished the cutting, routing and sanding of the slingshots today. I already have two coats of lacquer on them and will finish sanding them a little more tomorrow and put two more coats of lacquer on them. I did not sand these as much as I normally do because of my extreme allergy to the Yew dust. I made these a little shorter than I usually make, just to see if I liked them that way. As far as the wood is concerned, it is not very hard and tries to chip when routing. Because of the cost of it here in the states and also it’s not all that strong, I would not recommend it for slingshots. Also if I were making a bow I personally would use Osage orange instead of Yew. I will post a picture of them when they are finished. I have heard so much about Yew, I just had to try some. My favorite wood for slingshots is Hard Rock Maple. -- Tex
