I salvaged an aluminium drying rack for glass tubes. I already had some salvaged lab glass tubes and long bottles that I wanted to make racks for, and they fit nicely in the holes. However, I didn’t have enough of the bottles to fill it up, and it was too tall for the reaction tubes. So I drilled out the little rivets, sawed one of the plates with holes into two, and made the thing into two racks to fit both the tubes and the bottles.
It was nice to work with rivets again, I don’t have much experience with those. It shows if you look closely – the one in the back has four different sizes of rivets – but I learned in the end.
I’ll use these for propagating plant cuttings. They fit perfectly in the windowsill :)
