My part also had holes. Drill first and then mill it out. I never could have
done it if it wasn't for CNC.

Odd temperature range on the solder. I am familiar with soft silver like
StayBrite that is in the 450°F range and then hard silvers that go from
1100 - 1500 °F. Never heard of material in that middle range.
