Just a question...Did you preheat your mold or are you having difficulties with it "cold". If you did not preheat you might try
it.Just an idea.Good Luck

Anyway good luck.Another idea is to try heating your lead just a little hotter as a guy should not have to modify a mold to increase gate size.I have modified molds for larger hook size though...

Search for a post by DrNip on this subject. One of the things he talked about was placing the pour spout completely in the pour hole on that mold. I started doing that on my do it molds and it made a big difference.
I ended up opening the throat up to 3/32, which is what the Do-It molds are, and it made all the difference in the world. I hated to modify it, but I was frustrated.Quote:

Hey Barry,
Just out of curiosity which Jacobsen mold were you having problems with?Just wondering.Glad you found a resolve.

LOL, I don't know why I was calling it a "Jacobsen"??? It's "Jacobs". It is a 1/16 Pillhead mold.Quote:

Also had to physically lift the finished jigs from the mold. I attribute this to the shinier finish on a machined mold compared to what I think is a cast mold. Different animals. The smaller gates make snapping the spruce much easier but tricky to pour sometimes.Good luck with it
I use a mold release spray. It's for making your own bullets. Works great,I sprayed them really good the first time and now and then as touch up.

Hey Barry,
You have been given all kinds of good ideas from the CDC crew .I realize you have opened -up your gares for a resolve.That is water under the bridge so to speak.The first suggestion from all should have been to go to Jacob's website and read their casting instructions. Do-it provides instructions with every mold but I do not know if that is the case with Jacob's.Hopefully they do as that is probably your very best source of mold usage information .Good Luck and enjoy your tackle-crafting.

Mis-spelling above... "opened your gates"
