the setup: my set came with two different sizes of dapping punches and a
dapping block with corresponding hole sizes which I placed on a mouse pad. I
used a nylon hammer that we had at the office and started out with a copper
blank that is 1" in diameter (the same size as the largest hole in my dapping
to hold the dapping punch perpendicular to the block, like this:
hammering the blank until it conforms to the shape and size of the hole in the block.
This took fewer strikes than I anticipated! I then switched to the smaller
hole and punch, and refined the curvature even more.
not to polish the domes; I like the rustic appearance and plan to turn them
into a pair of earrings.
decided to experiment with a few other shapes (before, on the left, and after,
on the right). Notice that I was not able to shape the patterned pendant at all
(it was not malleable-see Mark's tips above):
watched another video about using the same method on stamped pieces, but I was
still curious as to whether the dapping process would harm the stamped words. I
started with another 1" circular copper blank, stamped words and an image,
colored the indentations with a Sharpie, then polished the whole thing with a
Pro Polish pad.
It worked just as smoothly as before!
