Progress on my second birch cup. First is big - 12 ounces for beer. This will be 6-8 for coffee. Different approach from first time where I used only hatchet, pocket knife and fire. This time I'm using table saw to rough it out and square it up. Made a few cuts and just one dumb mistake over cutting on underside where I couldn't see. Sliced handle almost in half. Forced to abandon long handle as originally sketched. Used drill holes throughout bowl, then chisel to start hollowing. I don't own a hook knife yet so the bowl is a challenge. I'm going to investigate a wood rasp bit for my drill.
