Just "upgraded" my casting arsenal with a Lee 20 pound "magnum melter" and a Lee 4-20 bottom pour.
The "magnum melter" will be dedicated to ladling wheelweight. It is a good value and does the job. Admittedly, the Lee temperature control system allows the pot temperature to wander quite a bit, but it's not a huge problem. Thumbs Up
for the Lee Magnum Melter.
The plan was to dedicate the 4-20 for pure lead. I hate ladling pure lead because it oxidizes like crazy so you have to flux frequently which is pretty unpleasant in the winter when you can't open the windows. In theory, a good bottom pour pot would allow you to cast pure lead while ignoring the flux on top of the melt.
Well, the 4-20 has given me a hard time. First time I went to use it, the pour spout refused to pour. The pot was 850 degrees so I knew the spout wasn't frozen. Eventually I unjammed the spout with a piece of wire. Out poured the hot lead ..... and it kept coming out, and out, and out, spilling all over the bench. Only after twisting the stem with a screwdriver did the pour stop. By that time, the pot was half empty. I had to clean up the mess, dump it back in the pot, and wait for it to reach temperature.
OK, finally it's up to temp and I start casting. Boy, that's a pitiful stream of lead -- looks to be 1/16", maybe 3/32" tops ??? It takes quite a while to fill each cavity. Bases are often rounded because the flow is too puny. Grrrrrr.
In between pours, DRIP, DRIP, DRIP.
The pour handle is located on the right-handed side of the pot. Who on earth pours with their right hand ?
How many decades has Lee been making the 4-20 ? And they still can't get it right ?
At this stage, I cannot recommend the 4-20. It is a piece of crap. Aside from the horrible leak, the pour stream is inadequate even for linotype. What is Lee thinking ?
However, before I use it for target practice, I'll try some mods. Drill out the pour spout, move the pour handle to the left side like god intended, and experiment with ways to fix the blasted leak. Stay tuned.
