again:

IMO it works a lot better to weld up rectangular frames of dexion square
25mm slotted tubing, sit that on the floor, bolt it to the wall and have
aluminium flats cut to length in the vertical slots and sit the shelves on
those. And have more verticals with the heavy stuff like bookshelves
so you can use the much cheaper melamine coated mdf instead of
timber or ply. And have the frame front to back distance so that the
long lengths you get from the shed drop in and only need to be
cut to length.

Darn, so far this thread has been Rot-free! And now the cretin HAD to butt
in with his senile rot again!
