Love it! Repeat as necessary..LOL
Use a deep socket that will slip over the stud and a big C clamp after removing the brake drum from the hub. Tighten the clamp firmly, then smack the end of the clamp screw with as BFH. Repeat as necessary until the stud seats itself against the hub. If you try to pull the stud in with a lug nut, you'll stretch or break the new stud. You can also support the hub over a set of vise jaws gapped open just enough for the stud to go between them and and drive the stud into place with a BFH and a piece of soft steel round stock.
