I messed up this time! Maybe some one can give me advice. Please

I have been fixing up this 1867 Swede Rolling Block in 45-70, the breech block looked like new, but it was rim fire, so I mark where the firing pin should be, locked the breeck block in a vise and drilled  my hole. with the line that the firing pin was going, I wasn't going to use the orginal screw that goes all the way thew the block and holds the fire pin from comeing out, because the orginal firing pin ( which I have never had or the holding screw) had a place on the firing pin that had been turned down  so wide, to let the firing pin have room to travel. After I had drill the block I knew that the orginal set up wouldn't work, but I thought I could cut a slot in the firing pin and use a shorter screw just so it would let the pin slide in the slot. After I made the firing pin, I found out there wasn't enough meat at the orginal screw hole to cut a slot. so Do I weld up the orginal holes and relocate the holding screw  pin, and place it where I can use the same princable they used? If someone  reads this that has done this, plese tell me how you did yours!
Thanks ACE

Ace,

On one of the RRB target rifles that I built on an original rim fire action I faced the same problem that you have.  I started by completly plugging the original firing pin hole in the breech block so that I had essentially a solid breech block to work with.

After marking the location for the firing pin on the face of the block like you did I carefully set up the block in my lathe and drilled from the location of the rear of the firing pin through to the front of the block with a pilot drill.  I then enlarged the hole to fit the new firing pin.  I was able to use the existing retaing screw hole in the breech block with a shortened screw and a notch cut in the side of the new firing pin.

I have drawings of the modifications that I made to the breech block and of the the new firing pin.  If you would like copies of these drawings send your name and address to me at wrheller@sbcglobal.net.

Hope that I can be of help.
