| Link in multi-metal chain. I had been wondering about how hard it would be to make a multi-part graphite mold with which I could cast chain links around each other. That is, given an existing link, cast a new one interlinked with it. This turns out to be quite do-able: Here is the mold I made (using my drill press as a vertical mill and a round-ended router bit):   In case you ever want to try this, I'll give you an important hint: The third link is the real test, not the second one. Using this mold I have cast a chain out of all the metals I can easily cast. Click the Sample Group link below to see all the links together. This chain (counted as one sample) is the 600th sample added to my collection.
