Foghorn, thanks. I haven't looked at Lee Valley yet, but something in that line to get me started.
Mike, thanks. With my hands I can get a good grip. The head was milled to be 1-3/4" square, then the 8* bevel cut.
Jim, thanks. The dovetail is the key to the strength, but I should not be whacking the chisels that hard. I was thinking the angle would allow for more of a square hit, I see if the angle works or if it needs to be adjusted on the next one.
