Thank you. It works well for me. I like yours too. I have not made the "key" yet as you have. I just use the wrench. We live in the woods and have lots of oak, hickory, walnut and maple. hickory is my favorite but the oak was already slabbed. I am making a smaller version for little tasks now. Still think I will sand the slope a tad more though.. thank you for looking and sharing. RainSpirit
