So I've heard of greensand folks leaving molds rammed up ready to pour for months before actually pouring metal into them. How long can you leave a petrobond mold rammed up before you have issues with it? I've got a bunch of patterns that need cast and no time to do it when the weather cooperates. If I can get molds rammed up while it's crap, and they'll keep. I might be able to get some parts out the door. Thanks, Bruce
That's great to know fish. Hopefully a nice weather (no rain/snow) weekend will be here within a month. But I can have molds ready when it comes.
Put a piece of paper or something over the sprue. Keeps the spiders out, it could be overly exciting if a big juicy one is down inside during the pour.
Or, something rather larger than a spider has taken up residence... like a rodent. "Don't be Bold - Address your mold! Guard it well, till it grows cold - Or the Sand-Man will come...."
Since my moulding bench is outside and the neighbor has multiple cats, I cover the sprue holes with rubber gaskets and then plywood large enough to cover the flasks. Every spring when we would fire up the tractors and 4 wheelers at camp, acorns would shoot out of the tail pipes. You didn't want to be standing behind them. Damn chipmunks.
