Re: Wood Truss Reinforcement

[Subject Prev][Subject Next][Thread Prev][Thread Next]
     The force transfer problem that you describe is similar to the flitch
plate force transfer that has been a topic on the list recently and (last?)
year.  You could search the archives for flitch plate and probably get some
leads for more options.
