Oooops....I meant Arsenal..^^^...not Accurate.
This thang wants to be beat silly to release these casts. I've done the eraser thing to the cavities and cleaned it spic and span with the brake cleaner spray...it shines clean like a new silver dollar...but it wants to hang onto those casts like a dog with a new bone!
I bought this mold used but it's in excellent shape. It's a big heavy hunk of aluminum and casts 2 ea. gas check and plain base.
Today was test run day and the keepers were only about 20% and that was a pretty loose standard as I don't think I'll use any of these due to micro wrinkles and such...they just are not perfect.
I ran the Pb pot from 650* through 750* and the mold ran from 385* to 490* on the hot plate...I just can't find the sweet spot yet...although that's not the worry as I can't understand why it wants to hang onto those cast like it does...there was a very narrow spot where they were falling out with minimal encouragement from the whacker...those were only a few.
Is the problem because it has such square lube grooves and drive bands?
Anyone using this exact mold? Do you have any tips so I can learn to live with this one? (Leement it...possibly to soften the edges?)
This is wheel weight Pb sweetened with 2% Pewter Sn. and the ingots were tested @ 16.6 BHN. It should be a great boolit metal.
