    Filing Machine

    I built this filing machine for the sole purpose of being able to file 90 degrees from a flat surface and to maintain that squareness no matter what shape or geometry I'm filing, I have used filing machines in different shops years ago and loved them, I do a little gunsmithing from time to time and everyone knows how intricate these little parts can be, You can only do so much with a conventional Milling Machine, Unless you have a CNC Mill which I don't have !!! So this was my only alternative.
    It doesn't have an overhead support for the file because the thickest material I'll be filing will never exceed .250"
    I made a ball and socket to hold any shape file, the ball and socket also allows me to square the file with the table very accurately, the crankshaft has a 1.250" stroke,

    Below are some photos

    Thanks for looking and Happy Machining

    Above shows the ball with a file in it, the socket is to the left of the file, the knurled nut is to the right of the file, all made from 4140 then heat treated and polished

    Above shows the file inserted into the ball and socket with a knurled retaining nut, the socket and nut both have the same radius machined into them as the ball

    Above shows the machine housing, fabricated from 1018 CRS, painted Rust-Oleum black hammered finish, the file assembly is just sitting on top

    Above shows the crankshaft installed into the housing, the crank is supported by two R10 sealed ball bearings

    Above shows the housing with the crankshaft and bronze linear bearing fitted over the crank pin, the crankshaft was made from 2" round pre-heat treated 4140, the crank pin is a hardened 3/8" dowel

    Above shows the linear bearing housing which is 4140 heat treated steel, slipped over the bronze bearing with the vertical shaft locked into the bearing housing by two 5/16" set screws

    Above shows the housing with the file holder installed on the vertical shaft, the precision ground table is ready for installation, the table was made from .500" X 6" X 10" 1018 CRS
