I thought folks might want to get a closer look at the cap-maker that Brushy was using in his video.
It was obviously patterned after the Forster Tap-O-Cap, but there are some distinct differences. Here's a photo of the new cap-maker on the left, and the original Forster Tap-O-Cap on the right -
The new cap-maker has a shorter cylinder body, made from aircraft-grade aluminum, while the original Tap-O-Cap had an all-steel body. Both machines have a steel rod anchored down in the base of the body (not visible in the photo).
The new cap-maker has a plunger/piston with 8 teeth on the end, made from non-magnetic stainless steel. The original Tap-O-Cap's plunger was a bit longer, and had 12 teeth on the end.
Both machines work the same way. First you insert thin sheet aluminum into the slot on the side of the body, and then you drive the plunger down into the body. The plunger cuts a disc from the sheet aluminum and folds it into a little percussion cap hull.
Here's a photo of the new cap-maker's hulls on the left, and the original Tap-O-Cap's hulls on the right (I used the soft sheet aluminum from disposable pie pans). The new cap-maker's hulls are almost identical to the old Tap-O-Cap hulls. They are the same length, and they fit well on the nipples of my Uberti and Pietta revolvers.
