In the picture above I'm starting out by knotching a fork blade that the dropout will insert into. The slot needs to be a few thousandths larger than the dropout.
Next I sandblast the forks inside and out to prep them for brazing.
Here I've brazed the dropout in with silver braze.
Next I spend some time cleaning it up. Sanding and filing.
And finally I assemble it into the fixture to braze the fork blades to the crown.
