Re: "Home-Built" Trusses

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Hello Fountain,

The "Midwest Plan Service" has a publication "Designs for Glued Trusses"

They suggest that you use 3/8" or 1/2" plywood for the gussets (on both
sides of the truss members)

They also suggest that you use Casein or Epoxy resin glues.

Finally, they recommend that 5d or 6d box nails be used to nail the gusset
to the truss,  nails spaced at 2" centers.

It might work.  BUT if he's trying to save money on the trusses is he
going to also have you design the trusses ?

I would use plywood.
