Re: Cerrosafe --how to use?
I knock mine out at 10 minutes. Cerrosafe shrinks for the first 30 minutes and then begins to grow. At one hour it is supposed to be exact chamber size and at the end of 200 hours it will have expanded approximately .0025".
From the Cerrosafe instructions.
The solidified casting should be removed from the chamber before, or when, it cools to room temperature. If allowed to remain in the mold over an hour, it will grip the chamber walls and be difficult to remove.
If a brass rod won't drive it out I believe you will have to melt it out. Your clock is ticking.
Oops, just reread your post. Looks like you got it out.
Some kids want to be a fireman or a doctor to help people. I wanted to be a gunsmith.
