Step 6: Assembly
Drill pilot holes at each end of the sides 1 hole in each plank.
Lay the first side onto the planter the ends should butt up to the B pieces inside and be flush with the end of the planter - thats what the 15mm gap at each end was for.
Repeat for the other side.
as the sides are screwed into end grain the will definatley pull out over time so go round the ends and base with a liberal sprinkling of nails 1 / 1/4" is about right and whack a couple of long screws through the base at each end up into the end pieces.
The timber I used is from reclaimed pallets and is already treated but I think I will end up painting them. I am going to line these with a horticultural textile to stop the soil falling through any gaps. I will add a step when I decide how to do this.
