chachybaby Posted August 17, 2011 Report Share Posted August 17, 2011 Hey guys, Was wondering if anyone could help out with this. I own one of the Do-it weedless jig molds. 3 cavities, 5/16,7/16 and 9/16 oz. The 5/16 and 9/16 oz cavities pour great. But lately I've been having problems with the middle cavity only. It used to work perfectly before. I've put a candle to the cavities, made sure they are not plugged or dirty. I melt the lead on a single stove top type burner, then further heat it when I'm about to pour with flame from propane tank. Also heating the mold a bit before I pour. I'm pretty sure I'm getting the lead hot enough, cuz the other cavities pour, but my end result for the middle cavity comes out with holes/unpoured sections on the back of the jig leading down to the hook. Its always the same area on the back of the jig that don't fill properly. Its driving me nuts!! Any help or insight on my methods is greatly appreciated.

Basseducer Posted August 18, 2011 Report Share Posted August 18, 2011 chachybaby, After you do all the stuff you normally do try putting the hook in the cavity and waive that porpane torch over it a few times. You may be getting everything except the hook tp to temp. Hope that helps. Quote Link to comment Share on other sites More sharing options...
Ogajiga Posted August 19, 2011 Report Share Posted August 19, 2011 Did you change to a different type of lead? Ladle pouring is very finicky to harder alloys especially in the collar area. No offense, but sounds like your pouring setup is winging on the cheap? A decent bottom pour melter might make it a lot EZr. Quote Link to comment Share on other sites More sharing options...
chachybaby Posted August 21, 2011 Author Report Share Posted August 21, 2011 no haven't changed the type of lead. Ya my pouring method is pretty old school, I should invest in one of those bottom pourers. Its just weird because it was giving me no problems before. If It was all three cavities, I understand, but its just the middle one. Quote Link to comment Share on other sites More sharing options...
smalljaw Posted August 21, 2011 Report Share Posted August 21, 2011 It happens sometimes when a mold is new and sometimes when it gets used awhile. Try holding it at different angles when you pour, maybe tilt it up slightly or leaning left or right, sometimes thats all it takes. Quote Link to comment Share on other sites More sharing options...

Jig Man Posted August 24, 2011 Report Share Posted August 24, 2011 I have a poison tail mold with some cavities that would not pour well. I did all kinds of stuff and finally painstakingly used some 600 grit wet/dry sand paper to smooth the inside of the troublesome cavities. That along with smoking and cracking the mold made them pour a lot better. Quote Link to comment Share on other sites More sharing options...
chachybaby Posted August 24, 2011 Author Report Share Posted August 24, 2011 ya I even tried opening the colar area a bit by sanding it down lightly. It calls for a 4/0 in the middle slot, but I noticed the the hook comes very close to that back part of the colar. This would surely increase chances of not filling properly around the hook. I thought it would help and it did a bit. I get fewer messed up pours from that slot now. Still inconsistent though. Quote Link to comment Share on other sites More sharing options...
crankpaint Posted October 8, 2011 Report Share Posted October 8, 2011 you might try another hook that sometimes helps diff. make maybe? Quote Link to comment Share on other sites More sharing options...
bass100 Posted October 8, 2011 Report Share Posted October 8, 2011 There is nothing wrong with your pouring set-up. A bottom pour can increase productivity and make the work area a little cleaner but it doesn't produce any better of a product than ladle pouring. If your lead is not fluxed properly then it will show in your ladle pouring. 90% of the time it is the lead you are using. The softer the lead the easier the pour.

Salty's Posted October 8, 2011 Report Share Posted October 8, 2011 Can you put an air vent in there? Could it be captivated air keeping the lead from filling out? Quote Link to comment Share on other sites More sharing options...
sdsaw Posted October 8, 2011 Report Share Posted October 8, 2011 Try brushing a small amount of baby powder into the problem cavity. It's been doing the trick with problem cavities for me. Doesn't last for more than 4-5 pours but does do the trick Quote Link to comment Share on other sites More sharing options...
chachybaby Posted October 10, 2011 Author Report Share Posted October 10, 2011 will do, thanks guys Quote Link to comment Share on other sites More sharing options...
jp48 Posted October 18, 2011 Report Share Posted October 18, 2011 I don't get on much, but pour my own jig's. A previous member on this forum recommended Frankford Arsenal Drop Out! I was reluctant to try it but I ordered a can 6oz $9.40 plus shipping. A bit pricey , you spray it on your jig molds and let it dry! it will last a long time! and It is the Cats Meow! I wouldn't ever pour again without it on a mold! the jigs drop out of it like there greased, and I use it on my DO-It Molds! what a difference.
