Never seen anything likr that before.... I wonder how useful it would be for dovetails... To me it does not have enough reach across the table to do wide dovetails, by the time you angle the head inwards..
I wouldnít mind betting that was more intended for blade grinding, as in Guillotine and folder blade work & paper slitters etc.. Elbís were kind of famous for that. Lots of their latter CNC stuff was for grinding Turbine blades.
Thatís a Wigglesworth Video. (Been discussed in General before). It wonít be the first time they didnít have a clue what it was they were selling.
