Here are some photos of the progressive steps in making a scabbard tip/chape/drag. First two is of the two halves hammered to shape on the form and ground, then sanded to the wanted height on the side of the scabbard. The contacting edges have been sanded dead flat to fit together with no noticiable visible gaps when brazed. Silvaloy 355 silver braze will flow into the joint even though you may not see any noticeable light through the joint. However, I would recommend you not sand finer than 220 grit on the edge faces.
The photo below is the two halves held together in the desired position with fine steel wire, and fluxed, ready to be brazed.
This photo shows the two now as a unit, and the wire ground and sanded away. You can see that the length is yet to be fully determined and have the top trued.
Here, the top has been trued and most of the sanding and clean up is done
And here is the 99% finished piece. It only lacks a polishing buff progressing from black compound, to green chrome, to yellow jewelers rouge, and then it can be mounted to the scabbard with glue.
