Homemade Cottonwood Roof Trusses

[Haytrader]

I have made several trusses with waffer board, construction adhesive, and staples.
These are the only ones that aren't covered by sheetrock.

I have a Paslode stapler and a lot of 1 1/2 staples so my theory is use what ya got.
I have used various adhesives including Liquid nails and have not had any problems.

I fell for the marketing and I agree their marketing is effective, but I have had no failures with the glue. First time I used it on a dock was in 1999 and it is still holdin just fine.

Sounds like I'm on the right track anyway.  Now I can buy a framing nailer to build the trusses and then frame the rest of the building.  I believe the framing nails are .131 if I remember correctly.  Good thread!

Thanks for the info!!

I wrote the Am Ply Association's Help Desk, asking if osb could be interchanged with same thickness ply in the ag service plans seen on the net. Here was the response;

Allowable design properties of OSB are similar to those of plywood. Interestingly enough some of the important mechanical property characteristics of OSB are superior for gusset applications.

An engineer can design truss gussets from either plywood or OSB. Assuming that panel axial tension capacity is the critical characteristic we would expect specifications for gusset thickness and nailing to be the same whether plywood or OSB. However, we cannot make a blanket statement that OSB gusset panels can be substituted for specified plywood or visa versa.

just have IRL exposure to this ..

built trusses using OSB and ply and both with nails and staples...
and of course construction adhesive...
had to take some of them apart...
ply with glue and nails were the toughest to break down...
