80-10 Imperial Guard Mounted Mamaluk
Venting Instructions
|
The Mamaluk kit is one of the most complicated models that Prince August has ever produced. In order to create the full detail of this magnificent cavalryman and to place him in such a realistic pose we have had to make the kit in 11 pieces. The number of pieces has necessitated that we lay the pieces out in the mould in a certain way. In order for the home caster to get the best results from the mould it is necessary to cut vents into the mould. The vents allow excess air to escape and enable the cavities on smaller items to fill completely.
The only tool needed is a very sharp craft knife or scalpel. Always cut away from you. To make the vents cut a contiuos V shaped groove into the rubber from the area which needs venting (see broken lines on diagram below) to the edge of the mould. Make sure your vents follow the lines on the diagrams as these show the correct direction for the flow of air. The vent need not be deeper than 1mm, if the area still does not fill after venting try to make the vent a fractionally deeper and make sure that there is contact between the vent and the part. Before venting the part try out your cut on a blank area of the mould. It is possible also to vent the moulds with a mini drill. Drill the hole from where the beginning of the vent line would start completely through the mould. Make sure the hole is free from any blockages. If a mould has been drilled it is not necessary to put in the vents but they can still be cut as a back up. Once the figure has been cast the there will be small marks where the vents have joined the piece. It is easy to remove these marks with a file. |
Every mould is different, test cast & vent the parts that don't get filled
