If the rest of that stove was in great condition, then this would make sense. We have some guys here who have graduated from aluminum casting up to iron and built several cupolas. I don't know a whole lot about that, but i do seem to remember that they had several adventures with it before they got it to work well. I think they do about one pouring session a year with it, and accumulate seveal patterns to pour when they do it. Jon |

I have plans to build a smaller furnace - sized for my small homemade clay crucibles - to cast brass/bronzes . The big one works but is not efficient for the size pours I plan to do in brass . I have no plans at this time to try iron . -- Snag |

Jon Oh , and the rest of the stove is pretty clapped out too , has steel plates where firebrick is supposed to be , shows signs of serious overheating around the flue thimble . My bet is it has seen more than one flue fire . -- Snag |

Christ! No wonder the guy wanted them repaired instead. Stoves are a real ripoff from the start, though. Thats a "grate". It would be easy to weld up something that would replace it using 5/16" flat stock. Hell..take it up to 3/8" or even 1/2". Easy to lay out, easy to weld up. Could do a grate in about 5 minutes with a MIG welder. Lay out a bottom course, lay flats across that..mig em together. Stainless ..can be done..but would be pricey unless you find a good source. Id simply weld one up out of CRS and be done with it. It will last for 50+ yrs and none of us will ever worry about it again. Gunner |

I mean, when casting news grates, one gets to try all sorts of new things. It's "rec.metalworking" after all. I would amble down to my local fab shop with a drawing or a CAD file and ask them to cut it out with laser or plasma, from the appropriate thickness of mild steel plate. If they're friendly and if you're lucky enough to find a big cutoff they have in their scrap bin, they probably won't charge much. Or take them a piece of plate from your local scrap dealer. It will be better than any c.i. you can buy or cast and a lot better than anything you could weld. You assume there *is* a local fab shop ... the closest we have is a small CNC shop that makes widgets for the gov't or something . "NO we do NOT do small job shop stuff." Well, as I said, that's what *I'd* do. g There are two shops with laser plate cutters within a five-minute drive for me. Likely at leat 10 within 20 minutes here. And my partner in the plane building project has a plasma cutter in his garage at home. |

I mean, when casting news grates, one gets to try all sorts of new things. It's "rec.metalworking" after all. True indeed. If one wants to cast a new one...by all means. Wax casting might be a good method. All one needs is 40 lbs of wax, lots of green sand, casting box, and someway to melt down humm..50 lbs of cast iron and then pour it into the mold. Simple!!! And one could use the old one as a direct pattern!! I believe that pattern makers have to use a "shrink rule" to make the pattern a certain percentage larger than the desired casting. And exactly what percentage is used is a function of what metal is being cast. (Starrett used to list multiple shrink rules in their catalog.)

True, but some times the part grows rather then shrinks. Gray cast iron, for example, has a stated shrinkage of from -2.5% to +1.6. (note: a shrinkage of -2.5 is actually a growth :-) -- cheers, John B. |
