So, now that I have a much better understanding of cabinetry and woodworking, I decided to revisit this. I think I may build new faces as Drew suggested. If I'm going to bother to do it, I think it's going to be the start of a long redecoration of the house. I'd like to get it to more of a hardwood finished home, rather than painted trim and cabinets and such. That includes either refinishing or refreshing the hardwood floors, replacing painted trim with stained, etc. Replacing interior doors or maybe just stripping and finishing them. Everything is in good condition physically but old and has enough coats of paint that just repainting isn't an option.
When the time comes to start, I'm going to take that island, and see exactly how the face frames are attached. If they're not glued on, and I can get them off without damaging the carcasses, perfect. I'll build new facing.
I was at Lowe's the other day looking at their various cabinet door options just to get a feel for what different woods looked like in cabinet doors. I want to do simple construction and use the wood itself as the primary feature for a country/rustic look. From the woods I looked at (cherry, maple, oak, ash, hickory), I definitely thought hickory worked best. Good color variation and personality in the features. Hopefully I can actually get enough locally at a price somewhat comparable to the others.
