Pouring update:
I cleaned out the pot, removed the spout closure bar, and cleaned out the spout. There was a ton of crud in it, and in the bottom of the pot. I sanded the inside of the pot with 400grit wet and dry, and then sprayed WD 40 into the pot, and on the closure bar. Then I sprayed isopropyl alcohol into the pot, and wiped the closure bar with alcohol.
I blew out the alcohol with my compressor, and heat dried everything with my hair dryer. I sprayed Drop Out into the pot and spout. I sprayed Drop Out on the closure bar, too. I let everything dry for several days, and then reassembled.
In between steps on the pot, I fluxed 9lbs of lead with paraffin and burned it off with a lit paper towel. I skimmed all the crap (dross/) off the lead, and poured it into 1/2lb and 1lb ingots.
Today, I heated the pot on 7, and melted 5lbs of lead ingots. I put my mold on top of the pot while it heated. While the lead was melting, I put a teflon bowl under the spout to catch any drips. There were none. Once the lead was melted, I lifted the spout closure rod to see how it poured.
Holy crap! The lead flowed in a beautiful steady stream into the teflon bowl, and shut off, with no drips, when I released the handle.
I did one pour with no hooks, and everything filled completely, so I loaded my hooks and weed guard pins. I put the mold in my metal working vice, and gave it a good squeeze, to make sure it closed completely with the hooks in place, and then I poured my first batch.
They came out perfect! I wound up pouring 10 each of 1/4oz, 3/8oz, and 1/2oz weedless arkie jigs.
Thank you all so much for all your help!
