Thanks Timberwrestler. I was getting the tool to be highlighted and I got the peg tool cursor. Someone from this list notified me off list with the key to getting this to work. You get the error I described if you click with the peg tool in the joint and then drag across the cheek of the TF joint tenon. The problem was in the dragging to the location of the peg hole.

I was able to get the tool to work correctly by clicking once in the joint and then clicking again (not dragging) near where I wanted the peg to show. The tool places a peg hole at that point, and then I could modify the coordinates to be exactly what I needed in the VCB.

I really appreciate the help I got.

Thanks
