Basically it is a shoe/baseplate for a 125 angle grinder to enable a cut action on sheet sheet similar to a rotary saw on ply.
It s made to utilise the 1.6mm ? x 125mm cutting wheel. It increases the safety of the operation by a good factor.

No drawing or plan was offered but its not that hard to guestimate some dimensions based upon your own angle grinder.

Checkout his other projects , there are some interesting ones there and they are well executed.
