The key (ambiguous) word there is “spread”…Not by forging them
wider, but by spreading apart the two pin stems. You end up with a U
shape where the base of the U is narrow (where it goes through the top
tube) and the arms of it widen out into a very open-topped U. Hard to
describe…did that help? Sharpening the stems has nothing to do
with this stage—it just precedes it.
Also, when I have tried a variation of this, I placed my tubing
perpendicular to the line that the pin stem followed - the end of the
pin stem wire close to the tubing (vs. the end by the catch) would be
bent down and the pin stem coming through the tubing would then be
bent at a 90 degree angle so that it would not come out of the tubing
and it would follow the horizontal line of the piece to the clasp.
Could you let me know if we are on the same page and clear up my
confusion on the part in quotes?
Sounds like you are thinking of one short end of the pin stem and one
long one (otherwise I don’t think you’d talk about a end close to the
tubing). In the double wire version, both pin stem ends are the same
length, and both get caught in the catch. Otherwise, yes,
perpendicular, right angle, the rest.
Makes you wish you could attach pictures to messages, doesn’t it?
