With the box glued together, it is time for the next step: taking the top and bottom off again. And yes, this really is the best way to do this. By making a closed box first, you ensure that the box is correct and the corners and everything is aligned. The doors are going to be 7 cm deep, but the closing extrusions will also add about 1 cm to the door.
And here is the first side done.
After taking off both sides I started making the closing extrusions. I chose to use reversible extrusions because you waste less and you can use the same on both sides which is better because I have to think less when making them.
After a lot of cutting (8 frames per side) the doors were finished.
To be honest, the project costs a LOT more time than I expected, but it’s worth it.
