[Shop-talk] Repairing a clasp--could be shop-related

What kind of steel wire?  Paper clips aren't very "springy", I would think
you'd want something more like piano wire.  But twisting it into a loaded
spring shape while stuffing it into the joint sounds very difficult (and
likely bloody) to me.  Obviously it has to be under considerable tension
when you're done.

> I believe it's known as a 'lobster' clasp

A quick Google turned up all sorts of lobster clasps with antique brass
finishes.  You might find something there that would work, without looking
too out of place.  Eg,

Go slow, and keep it moist with water.  You should be able to grind away the
end of the rivet without overheating the clasp (which might also be pot
metal that would melt easily).

OSH used to carry an assortment of fine spring wire (aka piano wire); don't
know if they still do.  If not, I could probably part with some from my
personal stash.
