IMPLEMENTATION OF THE BRICOPATE (paste)
1 - preparation of the paste
To avoid wasting paste, fill a box adapted to the dimensions of the future mould.
Place the dough in a hand covered with a glove.
Add the red catalyst in tube: 1 ml per 100g for a hardening in 10 minutes.
Mix well by hand for 2 minutes until the colour of the dough is uniform.
2 - creation of the first hull
Place the paste in the box.
Push half the thickness of the master into the dough.
Wait until it hardens. Squeeze the parting line with a sharp knife and remove the first shell from the box.
Cut two notches as a guide to bring the two hulls together.
3 - creation of the second hull
Brush the surface of the first hull with Vaseline (petroleum jelly).
Take the necessary quantity of Bricopâte (paste), place it in a hand covered with a glove.
Add the catalyst in tube: 1 ml per 100g for a hardening in 10 minutes.
Mix well by hand for 2 minutes until the colour of the dough is uniform.
Place the paste in the box.
Apply the first shell firmly to the second by overflowing the paste on all 4 sides.
Deburr with a sharp knife.
Wait until it hardens. Remove the second shell from the box.
4 - creation of the casting cone
Assemble the two shells with a clamp and drill an opening towards the centre of the mould.
Extend the opening to facilitate the casting of molten lead. The mold is ready.
