That doesn't support much. Most of the pieces were still in good shape the screws just had lots their grip. But one piece was broken.
Last spring I had to fix this too and I assume I have to fix this next spring also so I desided to do just a quick fix for it. I took my tools, some various lenghts of screws, a piece of wood and got started.
I drilled holes on the piece of wood and screwed the piece to hold the broken beam. I started out with only two screws but it wasn't very stable so I added two more.
So here it is all fixed, looks good to me. And it can now hold the heavy berry filled branches of the black currant bush.
