Re: casting Bronze porthole rings

I will try and take some pictures later of forms and core boxs BUT you need to spend some time on a foundry fourm and learn a bit more about shrink factors and core boxs

If your going to win at this you need to gain a better understanding of how a sand casting mold is made
