<div style="FONT-SIZE: 12pt; FONT-FAMILY: 'Calibri'; COLOR: #000000">Need some
metal working expertise. I know there is a simpler way to notch
metal than what I’m using. I had to fabricate a latch thingy for a
neighbor using 3/8” plate which required a rectangular notch to be cut in the
plate about 3/4” wide and 3” deep. I used a Metabo grinder with a .040
cutting disc to cut the sides but how to cut the back end of the notch. I
thought about a saber saw with a metal blade but the notch was very narrow and
it would have been difficult in that small area. Guess I could have used a hole
saw at the back of the notch and then squared up with a file...</div>

<div style="FONT-SIZE: 12pt; FONT-FAMILY: 'Calibri'; COLOR: #000000">I couldn’t
reach in the gap with a 4.5” grinder to hog it out... finally I drilled a number
of holes across the back line of the notch, broke out the slug and finished it
with a file to make it square. There has to be a better way. Can’t
find a hand tool to handle 3/8” material and notching machines aren’t in my
budget.. </div>
