Man I'm frustrated, and excuse my ignorance with everything as I am a newbie. This is my first mold and my second few hour session trying everything I could think of and have read on this site.
The problem is that the mold doesn't pour all the way down into the barb. Sometimes I get a partial rounded barb, sometimes it doesn't even get down to the barb. Once in a great while I get a good one.
I'll post a link of the mold at the bottom of this post, the 1/2 oz. seems to pour the best and the 5/16 the worst. I'm using the hooks they suggested with the mold. I get maybe 1 of 8 that pours good for the 5/16 and maybe 1 of 3 for the 1/2. Somewhere in between for 3/8.
I'm using a 10 lb. Lee melting pot with setting just low enough to keep it from getting red hot (around 6-7).
Lead I got from a friend and it's in 1 lb. bricks. It doesn't appear to be super soft, it does make a bit of a clank when I drop one. So maybe it has some tin mixed in or something, not sure.
I've read through a ton of posts and tried the following:
- heated mold
- heated hooks
- heated hooks and mold
- slanted the mold every which direction
- filled the pot up 2/3+ (this helped some)
- etched a couple small scratches from the barbs (nothing too crazy, I figured it was more likely something I was doing wrong and didn't want to do much to the mold)
- added some spacers that just created flashing and didn't help
- played with higher and lower temperatures
- held the mold closer and further from the spout
This is the mold (MF model):
