I had a contractor that wanted a 7" x 7"carved frog for the top of a newel post. My first question was what kind of wood, hickory, and then how will it be attached? Ouch, hickory! I have never carved hickory but I had a pretty good idea that this was going to be a challenge. A challenge wasn't even a good way of putting it. It was down right HARD! The end grain made it even harder, the grain ran up and down. I ended up using a Foredom and burrs. They wanted a spigot to use for the attachment. My part of this project is complete and I think it turned out pretty good. I'm hoping that the contractor can get some installed pictures for me and if so I will post them.
