    For those that always end up with caps that fit loose on you revolver nipples I am showing an easy way to cure the problem.

    Make a percussion cap crimper.
    Some time in the early 70's I made one just for percussion caps from a couple pieces of 14 ga. cold rolled sheetmetal.

    The crimper has a screw on the one handle to fine adjust the size of the cap crimp to make them a perfect fit on the nipples of your gun. puts a very small inverted bead in the cap skirt. cap stays round.
    To go with it I had made a wood dowel that has a bigger dowel over the outside of it that is glued on to inner dowel. This is to hold the cap and is the gage to put the crimp in the right place.

    I just set the cap on the small dowel, lay the pliers down against the stop with hole around cap, lightly squeeze the handles to hold the cap and take out the dowel then finish crimping.
    I haven't got it dug out yet so I am just showing a drawing of it for now but it looks just like this.

    drill the hole first before cutting the shape open on the end of each half of the plier. And then use a larger bit to drill the taper (counterbore) to the sharp edge. If you have a countersink reamer that would work. Then cut off the side of each hole to finish end of plier. drill hole for hinge bolt and put together.

    Someone out there gave instructions on how to make a pair out of needlenose pliers. You have to heat it cherry red to take the temper out of the wire cutter part, then drill a hole in it that fits the cap and nipple just right and then reheat it and temper it. He sits and crimps all the caps in his tin so they're nice and snug when he uses them. The wire stripper idea is good.

    While doing a search for caps info, I saw your old post about a tool for crimping caps. The text implies that there is a sketch, but I did not see one in the post. I cannot visualize what you made by the description. Do you still have the sketch? If so, can you send a copy?
