Hi peeps,
I'm completely new to woodworking and in dire need of help! I tried making a wooden planter with 45 degree cut corners and glued it together with Sellys aquadhere -the first one looks okay but the rest of the corners are terrible 😢
This was made with scap wood I found on the side of the road. I would like to try again with some 12mm thick tasmanian oak I bought from bunnings and coat it with tung oil (apparently it cures the wood and makes it waterproof?)

I want to create something like the planter on the right...any help would be greatly appreciated. Oh and I bought a corner clamp from bunnings but it never clamped the corners properly ... either that or I didnt use it properly?
Please help 😄
Kim
