Chavez;

Yes, I turned the chamber end to 1 inch in diameter. Note: The cutting of the relief depth is for the barrels to seat down onto the shoe lump platform rounded slots where, after seating and brazing the center of the barrel chamber end will be at the dead center of the firing pin holes when the barrels are closed. Therefore the fitting of the shoe lump to the action face and action flats and hinge pin ("jointed") must be done prior to the barrel brazing. The thickness of the shoe lump platform also has to be calculated to ensure the centering of the barrel chambers to the firing pins.

No, I did not have problems removing the hinge pin from the action.

A ring torch or similar is prudent. Go to YouTube and watch the Verney-Carron video and watch how they braze the barrels to their shoe lumps.

That amount of silver is too low for me to consider using. Use something like Silvaloy 355. A silver braze that flows in the temp range of 1250-1275 degrees F with 55 to 60% silver. No cadmium.
