I wanted to make s dear friend a potting bench made from old pallet wood. I'd just picked up a load of single use pallets from a local tile store. Unusually, there were some some 2.4m long pallets which were perfect to make the long "L" shaped legs for the back of a potting bench.
It took about half a day, but then I do have a good chop/table saw, plus I used outdoor glue and air staples for most of it with wood screws for the framework underneath the bench proper. I gave the whole thing lots of decking oil to finish it off.
