Thanks for your pointer Steve.

OK - so, a little build history will go a long way here - if you look at many (almost all) mass produced road bikes of the brazing era you will see what's often called a "domed stay" where it's rounded at the dropout end and the dropout just snugs in there - how do they shove in 1/2 a rod you wonder?

They don't.
They just 'lipstick' the edges around the end of the stay, maybe feed a bit more in at the back of the DO and on you go to the next 1000 you have to do that day and they last just fine!

Also, no need to cut it apart to see where the bronze is - just look at the dark cherry colored plug as it cools slower than the rest of the stay - this is the extent of your fill - indeed, many builders leave the stay 'lipsticked' around the edges of the slot and the end of the spearpoint is open to drain, no plug.........
