Stagio Posted January 22, 2009 Report Share Posted January 22, 2009 I have a couple of cavities that are geting a great deal of flash around the eyelet. This is a football and round shakey jig multi size/hook mold. I use the 32798's in it pretty much exclusively. Is this because my lead is too hot, because I use the nipple on my lead pot to inject and create pressure? Is it something I am doing and is there a way to fix it?

Basseducer Posted January 22, 2009 Report Share Posted January 22, 2009 If you have been pouring these molds sucessfully in the past, you might want to check the machined surfaces on the mild. Sometimes a tiny spot of lead gets on the surface and is just enough to cause a little flash. Quote Link to comment Share on other sites More sharing options...
Stagio Posted January 22, 2009 Author Report Share Posted January 22, 2009 Thanks TJ. I went throuhg and cleaned the mold really well and it is still doing it. I think over time somehow the mold has worn down right where the eyelet leaves the cavity---if that makes sense? I generally remove the jig by the sprue and I have never used larger hooks than recommended so I am not 100% sure how it has happened, maybe it is just the nature of the beast. Is there something i can reshape this with beyond going to a machine shop? I saw some posts that said using JB Weld but I am a little leary of ruining my mold. I have gotten pretty quick at removing the flash but its hard to get in a grove when you are constantly haveing to "repair" product. Not sure what the life cycle of a mold is but maybe its time for a replacement. Also, I think I bought my fluid bed from you. Great product! Cut my paint useage and eyelet plugging down SIGNIFICANTLY! Quote Link to comment Share on other sites More sharing options...
Basseducer Posted January 22, 2009 Report Share Posted January 22, 2009 I get this sometimes when I use a smaller diameter hook than is called for or going back to the recommended hook after using a heavier hook. The JB Weld is one method, but I can't coment on it as I have not ried it. One thing you can do is try turning down the heat and the lead will be less likely to seep into those very small areas. Just not too low that the cavity doesn't fill out. Quote Link to comment Share on other sites More sharing options...
Ogajiga Posted January 22, 2009 Report Share Posted January 22, 2009 Might help to examine your molds for complete closure both empty and with hook in place. Check how much light if any you can see thru the seam between the closed mold halves. Its rare to find a mold with a perfect flush seal & a little light showing thru is normal and actually facilitates air release from the cavities during a pour. If the mold cracks excessively when empty there might be a particle stuck on or damage to the mold faces preventing closure. If the mold cracks wider with a hook inserted than emply you have a problem with the hooks or there might be particle contamination in the hook slot(s). Mustad Ultra Points are usually consistently well formed but I did get a bad batch of 32729 recently with twisted and canted eyes which had to be repaired to allow full mold closure. I've got Do-its with 10s of thousands mileage which don't appear to flash any more than previously. Since you're having a problem with multiple molds I would suspect the hooks.

JSC Posted January 22, 2009 Report Share Posted January 22, 2009 Just a thought ... has this started with a new batch of material ?? Heat not being set right in counjuction with the material you are using can cause some strange things to happen. Let us know what you find.

Stagio Posted January 24, 2009 Author Report Share Posted January 24, 2009 Went through some old jigs to see if maybe "someone" had made a few jigs with the wrong hooks and I did. Must have grabbed out of the wrong bin or had one mixed in. The difference between a 4 and 5/0 is pretty huge, so I must have been a zone or luremaking lala land. I bought an expoxy putty called "Quick Steel" and I am hoping that will resolve the issue. Thought a putty would alow me to make an impression rather than using JB Weld which would be more trial/error. Stuff is good to 500 degrees which is a bit of a concern but i'll post and let everyone know how it works out. Quote Link to comment Share on other sites More sharing options...
21xdc Posted January 24, 2009 Report Share Posted January 24, 2009 Better yet... Drill out the eyelet areas deep and over fill with permatex ultra copper high temp RTV silicone. Let it dry and cut off flush with the mold. Now you can put the hook in and never worry about any flash. Works great. Quote Link to comment Share on other sites More sharing options...
