How do I screw 1/4 MDF from inside for invisible joint exterior panel

[griffindodd]

I plan on using 1/4 MDF for all of my front facing panels on my cabinet, they will all be covered with plastic laminate on their exterior sides.

I want to be able to remove the panels for service/modification if need be, I am happy to unscrew them with a screwdriver should that need arise. My question is how do I create these joints so they are invisible on the outside while being tight and removable on the inside.

As I am using a structural freestanding internal frame, the only thing I could think of would be to glue blocks on the inside of the panel and then screw those blocks to the frame inside the cabinet.

My frame...


Any other suggestions gladly welcomed.

Using 1/4 inch MDF... I think your suggestion might work best.  Glue blocks to the inside of the panels, and then you can screw from the inside and nothing will be visible externally.

heavy duty glue and pocket hole screws. here's a build thread for a sub my friend made me out of mdf using those exact methods.

I've never seen any pocket hole screws that would work on 1/4 inch material.

Yeah, a pocket hole won't work on 1/4".

I'd glue blocks and then screw into those.  There's really not an easier way with material that thin.

for some reason I completely overlooked that it was 1/4".
