Most of the rest is solid, but that one area is rotted all the way into the channel. I removed all but two large bolts and one smaller on that attaches the frame and channel together.
So, should i remove the whole piece? Or use Get Rot and some epoxy paint? I just struggle on how i am going to slide this piece of wood into the channel... How did they do that at the factory? At some point they had to have had cut pieces to do it otherwise how? I saw a thread where someone had done it with two and was spiced in the center. I thought of splicing it in two places over the frame where there was support for the splice.
