I am installing a 4 x 6 DF beam using a 3/16" knife plate recessed into a brick column.

I was hoping to get some tips on how to cut a pocket into the beam for the knife plate to insert. It is 13 1/4" deep with two countersunk bolts through.

I looked into a chain mortiser, but none of the rental shops in my area have one.

Thanks!

You can get a nice one from Mafell for 5 grand or you can build a chainsaw jig.

Is is for a porch roof with parapet walls and two brick columns. The beams run the perimeter and support the rafters. The beam seats are recessed into the brick columns and have a knife plate that enter the beam.
