Another interesting project.
This was sent to me, following an image that was emailed.
This was the image.
As you can see, a bit of an odd set-up.
So, I took a standard folding opener and removed the upper and lower brackets.
Using the sample lower bracket, a replica was made.
Put the whole thing together and end up with this.
The ring is on the top, as there was a trap point with the original set-up and I'm told that this works much better now.
