Well that's why I mentioned the Git Rot above...look into that closer, cause you won't have to cut it out...that stuff is VERY STRONG and forms a structural-strength core encapsulating all the rotted wood (gotta be dry)...take a good look...I think it'll do a great job and save you lots of time & $$$$ ...
