roof overhang knee brace design


can anyone help me find an attractive way of building a knee brace (AKA "bracket") to hold up a 2X6 barge rafter? the rafter is 10' long and is attached to the ridge at the top.

i made one brace out of oak, let-in 45 degree joints, and timberlocked. it took forever, but looks pretty decent.

i'd like to get the sort of craftsman style. would you make it out of 2X4? 4X4?

the roof is already totally covered, so i can't really go back and do "lookouts" or anything.

thanks.

Craftsman look-outs are 6" in from the house corners, not on the corner trim.

Measure the over-hang on roof, build the bracket 3" longer.

Do not notch anywhere on bracket, as per picture, not necessary. Make your seat cut in the barge rafter 3-1/2" wide. Slip the premade bracket up, nail or Timberlock screw into place. Be safe, G

thanks man.
so you'd make the brackets out of 4X4 material?
is it OK to use green oak? i've got a bunch of scrap left over from a job.
just pre prime it all?

thanks.

I would not use green anything, as it will shrink and open the joints. Mine are made from 4x4, then painted. 45* the nose all around, leaving a 1"x1" blunt point. Be safe, G

Depends on the roof load and barge rafter size; http://www.flickr.com/photos/5546567...-95238041@N00/
