Update:
I began where I left off. The brackets to which the folding side panels will be fastened. I glued two nuts with pratley.

Screwed shut.

Right here the bolts that fixes the panel to the hinge are reversed, because they are too long and collides with the other bolts at the back preventing the panel from closing. So I had to shorten them. A regular side cutter just won't cut it...

So I got out something a little bigger. A bolt-cutter. Hehe

I screwed every bolt in where they should go and cut them

And afterwards forced the nut out. This repaired the screw path ("die skroef draad" <- sorry, internal brain english dictionary out of date) This is pretty much the last thing I needed to do. Every part is now ready.

I took everything apart to prepare the big panels

After I sanded them and took the plastic cover off, all the parts are good to go.

The plastic covers can now be thrown away!
