Abstract

Present invention teaches a notcher having primary structures of a base plate with a mounting plate set in a vertical orientation. A square plate carries a pivotable trapezoidal plate that carries the notcher assembly. The square plate is slidably connected to said mounting plate wedges on the square plate where those wedges match to v-grooves on the side of the mounting plate. A T-post clamp serves to provide the holding structure to hold work pieces in place for the notcher assembly to do the needed work of cutting/notching out a hole.
