Here it is after annealing, before any work was done.
Here are some photos of the finished frame. All of the screws are of the pin spanner type which will hopefully discourage any "unauthorized entry" later. The floorplate screw hole was so badly funneled from the buffing wheel that I had to machine it to a larger diameter in order to get rid of the damage. Obviously a new screw with a larger head had to be made to fit the new hole.
