Hey @crosscreekcooter , you ever use wood epoxy to repair rotted wood that is too difficult to just replace? I've heard some good stuff about it. I'm gonna try this stuff from PC Products, the first part is a low viscosity "petrifier" that you brush on in thin coats after removing as much rotted wood as possible and it makes whatever is left solid as a rock. Then there is a two part putty epoxy that you can use to build up the wood until it gets back into shape. They say its stronger than the original wood and you can sand, drill, cut, etc. I would only need to use it on a few small areas but if it works it'll be way easier than pulling so much stuff apart to replace a small section.
I have used a repair product called Durham's Rock Putty numerous times in areas that might be difficult to replace. Not a petrifier, but a filler that truly becomes rock hard. It's a gypsum based product when mixed with water can be shaped, sanded, painted and stained. If it's an exterior situation wood had a tendency to continue to degrade so you have to be careful to make sure the cavity you are trying to fill is sound and dry. Whether you use an epoxy or some other filler, it is helpful to provide some mechanical form of bonding reinforcement (which could be a small nail or screw) between the wood and your filler inside the cavity to ensure it has a good bite.
edit: I notice their label now reads Water Putty-$2 for a one pound can at HD-that one pound can will make about 1 cup of putty, mix in small amounts as it begins to set rather quickly, short pot time, should be applied in successive fills
