Blowtoad

Okay this is a recent occurance, but now it's happening constantly and I'm seeking advice. When bringing the pot up to temperature the lower section of lead melts and just flows out of the spout. Not drips- Flows. It's untenable. The lead at the top of the column is still solid at this point- the lower area is liquid and flows until it's empty and I have a hollow cavern under the solid section. During this time I am unable to adjust the spout tube because it's stuck in place by the solid top layer. Now, once the leaking bottom section of lead has made its escape all over my work table, the solid top layer eventually melts down and I have no problems. I can fill it back up full when hot and not even a drip. I try to pour with a mostly full pot, and have had no prior problem brining a full cold pot up to temperature- until recently where it's been a nightmare. Typically I set the dial to max, then back it down to 6-7 to pour. I now resort to basically emptying the pot at the end of sessions and slowly feeding it lead once at temperature, but this doesn't seem normal. And again this hasn't been the case until recently. Any idea what's going on and how I can address this issue? Thanks lads

Update after a while, bunch of changes and testing- I THINK on these jigs in particular, twisting off the sprue deformed the lead a little bit, leaving some gap between the lead and hook (when the jighead has some wiggle to it)- The air in that gap expanded and caused the bubble. After dipping some new ones, I would put them back on the heat gun for 5+ seconds and pop I could see a bubble emerge at the shank or eye. Once that air was purged the melted powder seemed to backfill the hole and they're so far good to cure. A lighter coat of paint seemed to help as well. Thoughts?

Maybe 4 seconds rotated on the heat gun, knocking off excess after. You think it's a too hot/too much paint issue? When I do the 1/16 dips the powder almost always glosses over- okay or too hot?

It's got me baffled tbh. All my paints are protec. Sprues twisted off, quick file, heat shrink on the eye, and dip. These are 1/16, cured for about 15mins at 300. Seems to mostly happen on my small jigs.

Wagner 2-Temp (Amazon for ~$21) has been good for me. I like having the lower temp for heating up smaller jigs

I've been encountering (what seen to be) bubbles that appear while curing powder painted jigs. It basically leaves a hole in the paint and is always adjacent to the shank or eye of the hook. Doesn't happen all the time but it has happened with several different colors, and boy does it look lousy! Can anyone lend me some insight into what's happening? and also how to fix/avoid it? Thanks!
