I started casting about 4 years ago. I read all the books I could find on the subject. But until you ram up a flask and pore some molten metal into it in a furnace that you made, you won't know how to do it. Casting is fairly easy and the learning curve is fairly steep. Nearly all the problems I have had was because I wasn't paying attention to the books) The main problem that haunted my foundry was judging the temp. It boiled down to sometimes I got lucky sometimes I didn't. Every book I read mentioned needing a pyrometer. I was just to frugal to spend the dough to buy one. Their expensive you know) I can't remember where I got the idea but I found a pyrometer gauge for a kiln and a probe on Ebay for 20 or 30 dollars. The meter went to 2500 degrees, which is close to where I needed to be for bronze. When they arrived I made a quick handle that housed the meter and the probe. The wires go up through the pipe. Near the probe I had trouble with the wires starting to melt. I wrapped this joint with an old fiberglass glove and some KO wool.
Sorry, I had trouble posting pictures. Something about me forgetting my password to photobucket( I'll get them up tomorrow along with a link for those meters.
