No files? Hmmmmm... So you're gonna use a Dremel tool then, right? |

To err is human, to really screw things up requires a Dremel tool

We opened the frame window this weekend so I thought I'd post some photos: Base gun disassembled:   Locked in a vertical Bridgeport mill:  Indexing off the axis centerline (never trust that the upper and lower edge are completely parallel to the base pin):  Cutting the upper edge:   Cutting the lower edge:  The cylinder will be 1.80" so the window was opened to 1.84". That'll give 0.020" clearance on each side. It took a lot of passes to accomplish this. The stock window was 1.764" so 0.076" was removed. That's 0.038" per side and with 0.006" cuts it required 6 passes per followed by a clean-up run. BTW, Seville frames are hard as hell. Much tougher to mill than a Blackhawk. -Lee www.singleactions.com"Building carpal tunnel one round at a time" |

We used a 3/16" endmill which gave just the right radius on the corners. And I'm glad you're enjoying the thread. This is a special project for us so I want to document it front to back. -Lee www.singleactions.com"Building carpal tunnel one round at a time" |

Just curious where the valve springs and pushrods fit in the seville? Hahha....ya, our shop is a mixed bag of gun and motor projects. Keeps things interesting though. -Lee www.singleactions.com"Building carpal tunnel one round at a time" |

the bigger the toy, the bigger the fun...
1.84 window-1.80 cylinder = .040, / 2= .020 per side, though, right?
slick project.

I don't care how much you file, those firing pins and springs are never going to fit. ;D |

Measurements corrected above. We hope to blank the cylinder this weekend so updates will follow. -Lee www.singleactions.com"Building carpal tunnel one round at a time" |
