Maybe I dodged the bullet. All is well this morning, but I'm not taking any chances. My router has no dust collection, so I'll try to rig something. I'll also wear goggles and a dust mask, long sleeves etc. This is going to be a long walnut project and I don't want to nix it in the first week. I only have a little more router work to do, all the rest is hand work or machine work where I have good dust collection. Wish me luck!
