trying to add 10 inches to existing cabinet doors

You’re gonna have a grain matching problem. Even painting the doors will “telegraph” the grain through the paint. I’d replace the entire door.

Why not just build some new 10” doors? Maybe even glass doors so you can display knick knacks or what ever collectables you have. Or just build an open display shelf. Going all the way to the ceiling with shelves they’re going to be hard to reach anyway.

Or another thought, build 10” doors on both ends and in the center display shelves. Draw up some ideas and see if this will work for you.

there’s no way to stop this “telegraphing”?

and Terry.. I know they will be hard to reach..we’ll be storing stuff you don’t use everyday there, serving trays, fondue set, etc… stuff you need around just not at eye level all the time :)

You can stop the telegraphing and hide the seam with spackle. But, by the time you go through the processes to finally get a 10” taller door, you may as well have just built them to begin with.

Adding on to your exizting doors wouldn’t work for me. I agree with terry add some kind of doors at top. Maybe make a soffit with sliding doors.

oh I know I could turn around and buy a new set of doors… but I like to salvage whenever possible…even if it means more work…hard work keeps me out of trouble :)
so I don’t mind spending a few nights fiddling with this…as long as I can get good results

You mentioned you were painting the doors. I suggest making a NEW door. The doors are what makes the cabinet look good. Doing all the extra work behind and then “PATCHING the front” is not the way to go.
Use the old doors for another project .

Add a new 10” display cabinet to the top, make glass doors to match what you have now. You’ll have to get on a ladder anyway to access the top part, so you might as well make them seperate. I have done this with good results, Clients love them and display little used dishes/knicknacks or what ever. Can even add lights.
I’ll see if I can find one of my projects that I used this idear on.
Whats been said above about painting oak, it’ll never match.

some good point s floating around… I’m still debating what to do… have a few ideas floating around… this info helps!

I did mention this to a buddy of mine who worked as a cabinet maker for years and said that using bondo (auto body filler) to hide and gaps and wet sanding until my arms fell off… he claims that after that process no line would ever be visible

I wonder about wood movement… even I get the same type of wood… what if it contracts differently from the other…even if slightly, could that make that seam “pop out”?
thanks

I’ll go the same route as others and say build new doors. Will probably be less work and no worries of the seam showing or dealing with trying to hide the oak grain. Use some poplar frames and MDF panels, and you’ll have some affordable doors any size you need. Reuse the existing doors on a future project.
