Just in case anyone has any doubts about what parrots like to do to tree products... I was going to use this one for a caption comp, but the potential prize had to go elsewhere. Feel free to have a go if you fancy.
Anyway, the stricken planter. As you can see, all was not well at all. I ended up taking the thing apart in the end and found uncured glue on the mortises. Humph. I also took a fraction off the width of the panels in case that was exacerbating the problem. Trouble is I forget how darn dry the workshop is these days. Great for furniture for the house; all wrong for outdoor stuff.
Anyway, I broke out my little hatchet and some oak offcuts, rived me some peg material and drove it through the dowel plate to make some sturdy pegs.
All joints are now mechanically locked in (sorry, forgot to take a pic), so if it's gonna come apart again it's going to be so much harder to repair... Funny, the planter's not actually been outside for long, but you wouldn't believe the number of insects and such that high-tailed it out of there once I started in with the mallet. I know it's an oft-quoted thing that one oak tree supports some astronomical number of living things, but an oak planter...?!
