That is not a copy lathe i do not think it gives a rough shape. and cuts normally side ways leaving a rippled effect on bats.
The lathe is fitted with a initial shape (templete) and the 3 or 2 or 4 clefts under are rough copied to the template but it is not as neat as the picture.
It not a programmable thing it is a crude template copier.
However there a few little holes both top and bottom.
Dan does press a very good bat i have been there when he has done it.
