Aha, so its that plugin I need to check out, some news sites, CBS in particular, have videos that don't play either. Checking my plugins, did you mean M4V? MV4 isn't listed. > > > But thats an odd bucket for handling the hot alu. > > It is actually a very standard silicon carbide crucible these days.

We had to, at the beginning of each shift, repair the damage if any to the pour lips of our ladles with fire clay, and I never saw the core material of the ladle. They could have been some sort of a graphite molding for all I know. I believe the ladle was fitted into a circle welded up out the of about a 5/8" diameter steel rod the handle was made from, with a smaller hand loop to control the tipping with the right hand. With all the fire clay covering it, you had to let your imagination work overtime. As for silicon carbide, small town iron foundries don't have that stuff in their budget. > > > What I've used for > > casting iron was an equally long handled, fireclay covered bucket that > > we tipped over sideways to pour the iron out by rolling the loop on > > the other end of the handle to control the pour.

In the beginning it was just hard work, which at my age then wasn't a problem since I was also learning something new. We were making lots of seed plates for corn planters, and the gear cases for Maytag washing machines. The planter plates were made in several styles as there were many similar but different designs to fit all the major brand names. Each day shift 'set' as many sand molds as they could in about 6.5 hours, 2 plates to the mold. I was making about 90 2 plate molds of them a day. Then they'd tap the electric furnace & bring the iron around in about 500 lb buckets on an electric trolley, filling your ladle as it hung on the trolley. and go on to the next work position. You poured as many as you had iron for, then yelled for the bucket again, sometimes 3 or 4 times. The day shift left them sitting on the floor, and the night crew came in about 3 hours later, kicked the parts out of the molds, shoveled the sand mix back into a pile at each mans work position & ground off the flash off when it was cool enough to handle. They were also in charge of the sand mix, adding whatever it took to get the right cohesion for its reuse the next day. > I have a steel crucible that holds about 100 pounds of aluminum and > weighs over 30 pounds empty.
