Re: Cutting a Glulam Beam

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Could you cut the 4.5  inches  plus maybe 1/2";  route a  3/8" square trench
up the center of the bottom lamination and structural epoxy a steel cable in
place. To maintain appearance, fasten 1/2" face lumber over the steel cable.
Calc it out and you should easily be able to achieve the tension capacity of
the removed wood.
