Mcmaster T-slot Cutter: 8789A12

Cold-rolled iron rectangular bar

25mm x 150mm x 300mm is about 9kg. Iron density = 7.87g/cm3

Spacing from long edge: 25.4mm (1"), 76.2mm (3"), 127mm (5")

Use T-slot cutter on mill. (31/32" Cutter Dia, 25/64" W Face)

Match or be a bit less than the depth of the slot; firmly lock the height for this entire step.

Make the T-slot across the length of the iron bar.
