Building Shaker Style Cabiner doors out of MDF?

1/4” MDF panel glued into a real wood frame will work just fine. The MDF is dimensionally stable, easy to paint, super flat. Should not be any problem with that. You could use Maple for the frames.

I’m in a similar predicament- My wife wants shaker doors and honestly our cabinets are in such rough shape, I agree we need something new. Same thing- honey oak cabinets. FWIW, my plan is to get rid of the existing cabinet doors, build new shaker doors out of maple with a 1/4” panel slipped into the dados, then see if I can successfully fill the oak grain on an old door and paint it. If that works, I’ll fill the grain on the existing cabinets and paint them to match the doors. It all sounds good in my head, but I’m sure it won’t go that easily. I’ll be starting this project in a few weeks and if you haven’t done anything by then, I’m happy to pass along any lessons learned.

For the flex issue, I don’t know the answer, but maybe certain species of ply are better than others for this application? I planned on just using maple panels since the frames will be maple, but I don’t know if that’s the right answer.

I hear you on the cost advantages of MDF, but the way I’m looking at it is that by building the doors myself I’m saving a ton of money even with maple. And having more fun.

I would use poplar or alder for the frames
1/2 mdf for the panel. back cut the panel for the 1/4” tongue.

AAA, you answered your own question. 1/2” and 1/4”. The advantage of poplar is it holds screws better. Mdf is much easier and cheaper

So, maybe I wasn’t clear or maybe its such a stupid idea noone has responded to it, but I was thinking of taking 1/2” MDF, cutting it full size and then making a separate face frame out of MDF, assembling it, then gluing it on top of the panel I cut. No dado or rabbet – is this just a stupid idea?

I can do the dado/rabet, just it’s something I don’t do frequently and I’ve always had trouble getting it just perfect…

^You can do it the way you’re talking about, It’s not stupid.
But you will always end up seeing the line between the frame and panel.
If I was going to do it like that, I would rabbit it out for the panel, like so.
Miter the corners.

jbay – I thought that too – BUT, if I oversize the frame and panel by 1/4”, once glued together, trimming it to size in the table saw, then with priming and painting maybe the line would be hidden?

I also wasn’t sure about long term durability and swelling of MDF with moisture.

After 1 season the line will show up, although it won’t be horrible you will be able to see that a back was just added onto the frame.

If I understand your description correctly you plan to make the door entirely with MDF. I would be a bit concerned about how well the screws for the hinges would hold up.

Added: I see that Mike also mentioned the screws issue in his earlier response. I missed that. MDF is heavy stuff and not known for holding screws all that well. Glued panels in dados are great, but all MDF doors with screwed in hinges may well fail in the long run.

If you do this I Think what you will find is two things that you won’t be happy with.

1) As Jbay said, the joint between the layers of MDF will probably be visible, even if you cut it after assembly as you suggest. Maybe not the first year, but after some time it will appear.

2) The exposed edges of the MDF are going to take paint very differently than the factory smooth faces. I think you will be unhappy with the variation in the appearance of the edges and tops of your doors compared to the factory faces.

and they won’t hold up…..
