Sounds like you are gearing up for a serious cast.
Might be a little much though.
I got a double burner hot plate from a Flea Market. My shop is in one so it was just taking a break and walking around. The double burner types have the hotter larger plate. I use the small one for Wheel Weights, the Larger for Roof Boots. My lead melter is the Lee Pro 20. It does the trick. I like bottom pouring. I use vegetable oil to "flux" the melt, and Kitty litter to decrud it. I put Kitty litter on the melter, and lay the lead on the litter. It melts through without a visit from the Tinsel fairy. Water is bad with molten lead. It goes pop and the Tinsel fairy spreads her goodness everywhere. A mess at best, definite hurt if in the eyes or on the skin.
One thing I do, is on a fresh melt. I put the lead in the pot, then turn on the burner. As the pot heats up, the water vapor is dispelled and is gone. Any crud floats to the top and I then push it to the sides of the pot. I do have to scrape the bottom of the pot as crud forms there. It makes flakes and can make melting impossible. When I scrape that up, it floats to the top and can be removed.
Get a porous spoon also. You can clean the melt with that. Preheat it and scoop away. I find on my first melt downs, I get crud. As the lead gets cleaner, the crud goes away. Some oxides, but not bad.
Keep wheel weights from the roof lead. Wheel weights will harden the melt on cooling. Also, watch for zinc. It will float on the melt. Dump them. With wheel weights, I use a cheap pair of needle nose pliers and grab the clip.
I put both my hot pad, and melter on paving bricks. The splash usually does not go anywhere. Just drips and can be picked up and remelted.
I cast sitting in a chair. My melter, is at shoulder level, I push my sprue cutter on the paver with the dowel, I use a rake handle for that, them dump the castings in a large water container. My sprues can be put back in the melt after they dry. I like things simple. I make a hundred or so, then spend months shooting them. One roof job, can be at least 100 balls. I like things real simple.
Your tools will get heat affected so do not use good ones. Your pot handles will loosen, so get carriage bolts to fit in the handle threads.
Keep the work area clean, dry, and apart from anything that can fall into it.
Keep an exit in mind. Mr. Murphy might come visit on occasion. Never had a fire, but keep a fire extinguisher handy. And water.
Remember this is hot stuff and it does not care if you are in the way. It really does not.
I live it, but I also cast silver, copper, and gold. Just part of what I do.
