Today I'm doing a test cast to make sure my new casting torch is going to be hot enough. Last month I did a test run using my old torch and it barely melted the surface of my casting grain. I had to pull my glass torch off of the bench and use that to finish the job and even then, I barely had enough heat. My new torch will run on acetylene and tanked oxy - woohoo! HEAT!!!
Here's a pic of the rings sprued onto the rubber base:
Here they are with the metal flask around them:
And here they are invested. :^)
My burn out cycle is about 10 hours long so I will be casting around 1:30 in the morning, woohoo!!!
