I poured about 40 collerless jigs today out of a new mold I bought, when I went to powder paint them they seemed to have some oil on them and paint would not stick ..... i melted 4 tryin to maybe cook the oil off of them
so my question is what do I pre-clean my new molds with? I candle soot them before pourin but this time it seemed as if there was alot of oil on the mold
as always thank you all
Nothing beats soap and water. Be sure its dry because you DO NOT want to mix water w/ hot lead.
Flux and flux again. Clean the molds really good. Don't use a scented candle. Only time I had that problem was using a scented candle to heat my jig heads.
I've never seen a mold from Do-It that had oil on it!!!!!!!! I've taken them out of the bag, pulled the plastic wrap off the one side and started pouring. I've never used a release agent and NEVER understood why people soot their molds!!!!!
You've seen the trays of jigs I pour and only problem I ever had is with the double sided horsehead mold - 1 - can't use really big hooks and 2 - couldn't understand how I poured fine for 1 1/2hrs. and then the mold didn't want to close tight, with the 1/32nd size below the 1/16th I didn't notice a small piece of lead stuck on the bottom cavity and once I did and got it out I was back to normal.
thanks guys I think my problem is I'm usein a scented candle
the mold in question was in a long plastic bag from bass pro it looked kinda old maybe someone shot some wd40 in it ??
oh well like night prowler said good old hot soapy water and 40 mins in the oven at 300 degrees all is well
as always thank you all
I just got a new mold and there was oil it. It appeared the pins were over-oiled. About 8 pours with no hooks burned it off nicely.Quote:
