OK. So to create plywood gusset in the end like in this pictu

http://www.sweethaven02.com/BldgCons...02/fig0104.jpg

only make it as big as possible to reach as far back?

Since my sister timber will be right next to the existing one with the last
12" rotted out, how will this help? so instead of a 2x4, with my reinforced
timber it will have a total of 4x4 in size, how would a gusset along the
"side face" help? I must not be visualizing something correctly.

Thanks, MC

Homemade trusses were and are made with plywood gussets glued and nailed
instead of the gang press plates used at truss factories. You and I have
no way to press those plates into the lumber. The suggestion was to use
plywood gussets that you can glue, nail, bolt, etc.

Hi I am repairing some stained ceiling sheetrock in my garage, and
after removing some sections of it I realized there is more damage.

First the leak in the roof has been found and repair, so there should
be no more water penetration.

Now I can see the water leak has been there for a long time as the
end of the truss were severly damaged. The end of the joist and
rafter meet and they rest on the concrete block wall as shown below:

Now there is a truss every 24" or so but one of them directly below
the leak is damaged very badly. If you look at the image attached,
the section labeled "C" in green when I pushed it just crumbled. Now
the good news is that the roof is still up and it has been like this
for years this truss has not been supporting it's share of the load
for a long time now. The ends where it is rotted away is about 12"
or so in length.

I went up to the attic and tried to see if it's possible to remove
"A" and "B" completely and put new lumbers in but this is going to be
near impossible with all the AC duct work running across, electric
conduits nailed along it, ceiling hi hats and fans etc...and very
tight space.

So what I plan to do is to get two 12' 2x4s. I plan to put one
adjacent to the rafter and one adjacent to the joist for almost the
entire length. The question is now should I attach the two?

Should I drill a hole every 18" or so and insert large (1/2") bolts
through both and tie them together?

Or should I use some sort of structural glue/epocy to glue both
together?

Or should I use those galvanized steel tie/straps to nail them
together?

Or all of the above?

I also plan to insert some vertical wood members between the new
sister rafter and joist.

Or this is all wrong?

Thanks in advance,

MC

Cut back the rot treat the timber

bolt your timber either side , between the truss and timber insert
spike washers / timber connectors

Fit a 18mm ply gusset over the repair

before you do any of the above check the truss for alignment with the
rest of the system and prop it in place

Got it, except for one part - what is a 18mm ply gusset? Are those the
metal plates with lots of holes in it for framing nails?

Thanks.
