Problem with filling thin parts of the mould
I have a problem with filling small parts of the mould, such as the sword of the infantry man with the gun. Even after venting, heating and tapping the mould and using the best metal, the part of the sword does not fill with metal. I solved the problem with using other moulds for making the sword.
Tech support: You should not have problems if you use modelmetal. Test the temperature with a wooden stick like a burnt out match. Thirdly do you use a wise for clamping the mould. The air need to escape from the mould when you pour in the metal. Our clamps are flexible and opens up a micro millimeter and lets the air out. I hope this helps. If not email me some photos and we will come to the bottom of this problem.
