Casting Tutorial #3

After following the previous two tutorials you should be ready to pour the properly heated metal into a correctly clamped dry mold.

Pour the metal steadily, avoid hitting side of the pour hole. Do not stop until the pour hole 'well' is full. The weight of the metal in this 'well' pushes the metal into the extremities of the miniature (Fig.1).

(Fig.2 & 3) While pouring and for a few seconds after it is advisable to tap the mold gently with a piece of wood. This helps settle the metal in the mold.

You could also tap the entire mold, using both hands, off the table it rests on. But use extreme caution not to spill any of the metal on yourself.

STOP tapping when metal shows signs of cooling and stiffening (after 5 seconds or so) or risk cracking and damaging the newly cast miniature inside.

Slowly and carefully part the mold about five minutes after pouring. If the casts have not properly filled - DON'T PANIC.

You may have to try a couple of times to make the mold work.

If it still fails to fill awkward areas like reins or bayonets (Fig.4) then venting will be required. That is covered in the next tutorial.

Tips to remember:

  • Pour gently to fill the 'Well' of the mold.
  • Tap the mold gently for a few seconds after pouring.
  • STOP tapping when the metal begins to cool and stiffen.
  • Wait at least five minutes before opening mold.
  • If a gap appears in the casting, remelt the metal and try again.
  • Consider Venting for stubborn areas.
