Fitting the bottom plate |
|
|
|
The best 500 bucks I ever spent. |
|
|
|
Bottom plate Rivet holes counter sunk so rivets are flush with plate. |

Getting ready to rivet the bottom plate. |

I'm glad this part is done! I think it will look fine with a little finish work and Parkerizing. |

This is the riveting tool I made. It works in a muffler gun. The trunnion Rivets are much easier. A steel block and a hammer. |

Cutting the trigger slot to the new width after welding. |

  |
| 1st Time out! It sure feels good when you pull the trigger and she fires and everything works. Still needs a little work on the trigger. |
  |
| I took some more off the trigger to clear the bottom plate. Ran 75 rounds through it with out any problems. |

|
Parts blasted and ready for a bath |
|
|
| Warming up the bath. Below the bubbles and fizz are the parts. |
  |
| Not bad I guess for my first time over all I'd give it a "B" |
