    The Bishop's Jig

    Friend of mine, Mr. Bishop, is in to Black Powder firearms.....think Josey Wales handguns...and he had a jig made to help reload the old cap & ball pistols while on a range...just a "stand" to hold the revolver with the barrel pointing up....

    But, it wasn't working quite right...no place for the hammer to sit, at half cock...to allow the cylinder to rotate. My task was to re-do this jig for that problem..
    Decided to buy a bit of White oak, and a few hinges, and build a second jig...that when He returned with a revolver or two, I could cutom fit the new jig for fit..

    Cut a bit off the 24" long plank, to make the two parts...had to use the bandsaw, only room I had,,,

    Blade had too much set (have since stoned it back..) looks like i need to shoot the edges..

    Shooting board.. laid out a larger groove for the revolver's grip to settle into..Dremel with a cutting wheel to make a wall, of sorts..

    As the OEM one was at the wrong angle to hold the grips...Then dig out a gouge, and do a little chopping...

    A little wider, and a tad deeper, into a flat, vertical wall.. laid out for a hinge..

    And chopped a shallow recess for it...
    Stay tuned, part 2 coming up...

    Then screws were added to this side only, for now..

    Wax the screws BEFORE driving them in...yes, that IS a phillips tip in the Yankee 30A....

    The other half of the new jig had been cut to match the existing one...left alone otherwise, awaiting a fitting session with a Remington Army Model...
    That will be in part 3...stay tuned..

    Ok, part 3. Mr. Bishop brought a couple revolvers to the shop...and we custom fitted the new jig...a notch was added for the hammer, and a bit more room for the cylinder to set into...

    Notch was cleaned up with a chisel. laid this onto the old jig..

    And outlined what needed sawn out...hinges on the old jig ( with square drive screws, no less) was too loose and sloppy

    Recessed one leaf of the hinge...

    Then put things back together...same with Jig #2

    Then was told he wanted 3 jigs, total, counting the rebuilt one...by this time, I had found a VIX bit to make hinges easier

    Found a better way to hold the part while chopping grooves..

    Soon had all 3 assembled,,

    And stained...Any rough edges were beveled with a sanding drum in the Dremel...then fold these down, when dry..
    Mr. Bishop stopped by Friday to pick them up...was very happy. he was headed for a shooting match in IN. and was going to put them to work..

    Not a bad little project....
