Building new face frames for vintage cabs?
Wondered if any experienced woodworkers might be able to offer their insight on our current dilemma. We're attempting a kitchen facelift, and one of our challenges is that our beautiful 75-year-old built-in-place cabinets aren't deep enough to accommodate modern appliances (most notably a dishwasher). We're exploring various ways in which we might be able to adapt the original cabinets since if we gut them and replace them, we're not in a position to buy anything near their quality. I'm wondering whether it's possible to build a new face frame and either pull off the old and attach the new (it's somewhat loose already, but I'm not sure what it will do to the cabinet to actually pull it off) or, alternatively, attach a new face frame to the old one to pick up the extra inch or two that we'll need. (We would defer to a qualified cabinetmaker or finish carpenter to do the work itself, but I want to see whether what I'm proposing is even realistic before I start asking around.)
At the same time, we're contemplating getting new drawer boxes and doors for the cabinets. (The old boxes are pretty much done; doors could stick it out, but are designed for 3/8" partial offset hinges, and we've had trouble finding these. So did the old owner, apparently, and replaced several with awkwardly sized alternatives, which in several place required cutting chunks out of the cabinet face frames so the hinges would clear.)
Is it possible to do new face frames and doors/drawers all at once so that everything will be square, and then attach them to the existing boxes? The cabinets are 1939 built-in-place wood cabinets. They are not original to the house (house is c. 1915 and you can see the beadboard walls behind the cabs) so we don't think they're structural.
Would this plan work? If not, do we have many/any other options that might allow us to work with the existing cabinetry?
