Its just not possible to do such an undercut part easily with this method that I see. That's why I just tried a track pad but this alone is also undercut for the leading and trailing edges to mesh with each other track pad. So it didn't work out. What I want to be able to do is cast a track pad and links together without having to bolt the two together or have to machine each piece even more. Even if there is a way to do sand casting with the whole piece. I still don't think I'll do it. Its still such a long process to do just one sand mold for one piece. It would take me weeks for a set. My goal is to be able to cast a complete set of tracks in one day.
