Step 3: Cut Joints
I then labeled up which pieces were next to each other...it can get pretty confusing so it's good idea to mark, cut, and glue one block at a time.
Then I set up the dovetail jig, testing and tweaking it with some offcuts until the joints are coming out just right. I chose to use 6mm dovetails.
*UPDATE* dovetails are a bit over the top, you can get away with just rebating each edge 6mm and doing a rabbit joint with some pins, glue, and plenty of clamps. */UPDATE*
Then a long day of cutting joints! Make sure you're fully covered in your PPE, as this stage is very dusty...and MDF dust is nasty stuff.
