I bought willow blocks and linings for this project. I can't tell if I like it or not yet. I have only used spruce blocks previously. The top block was much narrower than the G molds upper block recess. I like my new mold it's easy to work with and the outline is very elegant. The rectangular whole in the middle is very handy. Time is becoming a problem again as I only have an hour here and there to be in the workshop.
