Just keep temps as low as possible so your crucible does not degrade to quickly. It sucks when your pickup tool does not quite fit the replacement after the inevitable melt through
The story about the boat and couple is amazing, use to listen to the wooden boat podcast and he did a couple of interviews over the years on it. She use to still come over to the festival in Washington. Cool to be part of history in the sailing world.I poured some aluminium bronze shackle parts for a guy named Larry Pardey and his sail boat Taleisin a number of years ago. Also bronze for my Gingery Lathe Top Slide. Past that only aluminium. Had I continued on the track to build a Lyle Hess cutter (still have the plans) I'd have cast much more of the parts and pieces for it. Maybe if I make a sailing dinghy or a steam launch. But for now. Just aluminium.
What are you casting in brass?
