The device is excellent for quick and precise cutting laminates for PCB. Stands for angle grinders are not very convenient, because you can only cut materials of small size and they are not very precise (large clearances on hinges).
Angle grinder 500W 115mm disc diameter was used. 9mm thick plywood 250x400mm was the top. An oblong hole was cut with a straight grinder placed in the cradle for milling.
Steel blade was used to cut the laminate. Additionally, an external speed control was used, because without that the edges are burned (11000rpm is far too much). Visible in the last photo protruding long M6 screw is necessary to diverge the grinder, to set the angle between the blade and the top.
