progressive BRAKE: construction details
The D- Ring at A11, C 11 or B11
The D-ring is home made of 1mm welding rod (used to weld stainless steel)
The D-ring has to be smooth since the bridle line has to slide over it as good as possible.
The connection to he sail must be rotation proof. In this case I used the existing bridle point.
If the D ring is allowed to rotate Bridle 11 will get entangled.
The O ring at Qp:
This is a simple commercial seamless steel o-ring.
This is how The O-ring is attached at Qp of the NPW-A//C.
The big o-ring is not necessary, that is just my way to make Qp
This is how it is attached to Qp of the NPW-HA
