Seat Stay Link for Belt Drive Modification

I wanted to have a link in my bike to utilize a belt drive (eg. gates carbon drive).
This is a brazing/soldering link for seat stays to open and close again.
For it has no loose part you have to be very carefully when opening the frame not warping it.
I recommend lateral orientation.
Of course it needs to be adapted when not having a 13 mm chain stay with 11 mm inner diameter.
There are two versions for countersunk screw and for flathead screws.
