It's been tough to work indoors now that warmer weather has started -- so much to do around the yard and house. But I have been taking a little time each day to do at least some small job on the lathe. Here is a pattern I just finished for the carriage casting: |

Looks nice Steve. I am anxious to see you finish this guy... |

Thanks Eric! :beer: Might take awhile. It threatened to rain today, but I took a chance and did manage to get the part cast late in the afternoon. It's a somewhat tricky pattern with a parting line up a short way, and needing to be coped down in the center section, so I had to bed it in a false cope first. Plus there's a greensand core that luckily held together. And it just barely fit in my larger flask. I had only a half inch to the edge at the riser. I was worried it would break through. The whole thing worked out first shot, so I'm happy. And it didn't rain! A few drops now in the evening. The raw casting....about 7 lbs: |

That's it, I am going to VT this summer so I can see some casting done in person. Looks nice! |

Sure Eric! But I don't have much interesting high tech stuff. That pattern was made of white pine scraps left over from building the bench. The casting was molded in plain sand mixed with fireclay (not even bentonite) -- ten years old, too. And melted in a plaster of Paris lined furnace, with a simple homemade half inch EMT tubing propane burner. And no blower. All this stuff detailed elsewhere on this forum in various places, so there's not going to be a whole lot new to show you! |
