is about 3" long, 1" x 3/4" made of cast iron and has a 1/2" hole in each end.
one hole is cross drilled 1/4" for a roll pin. The end is broken off across
this hole. I'm wondering if I should silver solder it or V it out and braze it?
I'm also considering putting aluminum rods it the holes to keep the flux and
brazing material out of them. What is the relationship between the melting
point of aluminum, silver solder, and braze rod?
