>>6610433Edit: If you plan on adding a lightkit, replace the Plate 1 x 12 (#60479) with two of Plate 1 x 6. Otherwise the original list is fine.
Capacity of the forge is roughly 250 studs with lightkit, 300 without. I recommend about 25 trans red studs, 25 trans orange studs, 25 trans yellow studs, and 175-225 trans neon orange studs. depending on your capacity.
Good luck!!
