    Hey Bob , what do you know about Lyman model 61 bottom pour lead pots
    ? I scored one at a yard sale last Friday for IIRC 30 bucks - older unit
    I think because it has the cast iron base . The mica at the power plug
    is destroyed but I managed a temporary fix for testing . It heats and
    melts the lead , but it dribbles . Is there a recommended way to clean
    up the valve area to stop that dribble ? This unit is going to make it
    viable for me to cast with the aim to sell a few bullets/balls to
    friends and neighbors . Not for profit but more to enable purchase of
    more casting supplies for whatever comes down the road ahead . .

    I cleared the outlet with a wire and let all the lead run out . It
    drips because apparently there's a bit of debris in the outlet . From
    the article you cited this is not uncommon , just annoying . I'll pull
    the rod in a day or two and clean it out along with wire brushing the
    whole pot . I think this is the first time this thing has melted lead in
    quite a while ...

    Also get nickel plated high temperature crimp connectors for the stranded wire. Solid wire is for stationary wiring that doesn't vibrate, stranded for anything portable.

    Look for one with type K thermocouple wire with glass or ceramic insulation, others might not be good for 800F. If necessary the hot section of the wire can be insulated with glass or ceramic beads, I've used wood stove gasket cement.

    PID is a sophisticated and precise control method that isn't really
    necessary for a lead pot. Ideally it maintains a constant temperature. The alternative is on/off control that turns power on at a lower temperature and off at a somewhat higher one, like a mechanical thermostat that needs a temperature differential between On and Off to power its snap action.

    I've got a couple of PID controllers that I housed in boxes and set-up
    so they can be used to control different kilns as the kiln plugs into
    them and the kiln power controllers are just set to 100% so the PID
    controller and SSR does the power switching.

    Lead oxides build up in pots over time. I believe the steel also scales
    up under the extended time at temperature. At higher temperatures its
    more reactive. I do not have a Lyman bottom pour pot, but I have an
    RCBS ProMelt 20lb bottom pour pot and a Lee 10lb pot bottom pour pot.
    Its almost impossible to stop the dribble. I just put a bar mold or a
    catch pan under the spout to catch the drips. After a partial
    disassemble and cleaning of scale, oxides, and whatever else is there
    the dribble is typically very little or nothing for a little while, but
    it comes back. Now I usually only clean my bottom pour lead pots when
    they stop flowing as well and it affects the quality of my castings.

    I've seen guys on tackle groups swear up one side and down the other all
    you have to do is clean it, or theirs never drips, but there is somebody
    who never has that problem or who's claimed solution fixed it forever.
    Like the guy who's racing pad bass boat never chine walks or even hints
    at chine walk at any speed from 0 to 200mph, and he hits those speeds
    with a bigger boat and a smaller motor than anybody else. LOL.

    P.S. I had a bass boat that didn't chine walk at any speed, but it was
    a twin tunnel. Not a common racing pad design. It ran like it was on
    rails.

    Anyway, depending on who you believe it might be possible to reduce the
    or eliminate the drip, but it might be easier to just accommodate it.

    A long time ago before I switched over the the RCBS ProMelt pot for my
    primary test melter I did reduce the drip on one of my Lee pots by
    increasing the weight on the lever arm that closed the valve. It was
    not 100%. It was just better.

    For larger castings I don't bother with any of my electric melters. I
    use a propane turbo burner, and a cast iron pot I found somewhere that
    has a pour spout.

    The Lee pot uses a simple analog control. The older style RCBS Pro Melt
    used a slightly better analog control. When they switched to a digital
    PID control it almost destroyed their lead pot business. Fortunately
    for them they sell decent quality molds, dies, and other reloading
    supplies. RCBS quit selling melters for a while, and finally they got
    their digital control working properly, or more likely started buying
    them from a more reputable Chinese supplier. I can't speak to whatever
    lyman uses. I have a Lyman ladle pour melter, but not a bottom pour
    pot. Their ladle pour melter has ALWAYS been a little cooler than I
    would like at max temperature setting.

    As long as I stay below the vapor temperature I'm good. Most lure
    casters run from about 775F to about 850F. To hot to check with my NCT.

    -------------------------------

    I snatch up used crimpers at flea markets and use whatever fits best. If
    they have calibration specs they no longer meet, like pulling tight on a certain size of drill bit shank, I shim under the dies. For home use a
    perfect crimp that properly strain relieves the insulation isn't as
    important as for a machine that will be jolted in the back of a
    cross-country truck.

    The old Stanley 84-203 crimps tight enough to pass a pull test on most everything.
    https://www.ebay.com/itm/226842087604

    https://nepp.nasa.gov/files/27631/nstd87394a.pdf
    Table 12-1 on p.54 gives the pass/fail limits.

    "For those contact-conductor crimp connections not contained in Table 12-1, the
    tensile strength of the crimp connection shall be no less than 60 percent of the tensile
    strength of the wire. Reference the manufacturerrCOs datasheet for wire tensile strength."

    Straightening solid copper wire by pulling it past its yield point gives a good feel for wire strength. I've seen the pull force test machine but never anyone using it, an experienced tug by hand was enough.

    At work the company bought the proper tools, which cost as if they were hand-crafted by Swiss watchmakers.

    Thats a method I teach for using stainless safety wire to make wire
    forms. Its not perfect, but its pretty good. Spool out several feet.
    Clamp one end in a vise and the other in a good pair of locking pliers.
    Then back off until you feel the wire "give." Cut off the ends, and
    start cutting lengths fo the forms. For heavier wire forms I typically
    start with straightened wire. 308L TIG wire is a good start with a few standard sizes available.

    PID is a sophisticated and precise control method that isn't really
    necessary for a lead pot. Ideally it maintains a constant
    temperature. The alternative is on/off control that turns power on at
    a lower temperature and off at a somewhat higher one, like a
    mechanical thermostat that needs a temperature differential between
    On and Off to power its snap action.

    The Lee pot uses a simple analog control.-a The older style RCBS Pro
    Melt used a slightly better analog control.-a When they switched to a
    digital PID control it almost destroyed their lead pot business.
    Fortunately for them they sell decent quality molds, dies, and other
    reloading supplies.-a RCBS quit selling melters for a while, and
    finally they got their digital control working properly, or more
    likely started buying them from a more reputable Chinese supplier.-a I
    can't speak to whatever lyman uses.-a I have a Lyman ladle pour melter,
    but not a bottom pour pot.-a Their ladle pour melter has ALWAYS been a
    little cooler than I would like at max temperature setting.


    For calibration the melting point of pure lead is 621.5F, 327.5C.
    This shows the effect of added tin:

    As long as I stay below the vapor temperature I'm good.-a Most lure
    casters run from about 775F to about 850F.-a To hot to check with my NCT.



    -a For my test run I had the thermostat set at 650 . Don't know the
    alloy that was already in the pot but it looks like probably pure lead .

    Pure lead or atleast soft lead is usually used for muzzle loader and cap
    and ball bullets. Hard cast is usually used for cartridge bullets.

    You can get the best "known" alloy from RotoMetals. You can get the
    most consistent lower price hard cast or soft alloy from PBCastCo. You
    can get the cheapest lead usually from lucky scavenging or the local
    scrap yards.

    I think 650 sounds awfully low for good castings, but you can't really
    trust the temperature on an analog dial. You just turn it up until it
    works, or you max it out. If it uses a thermocouple and a PID
    controller you can usually trust the digital display is pretty close.

    "If you have to replace any wiring in there go to an electrical
    supply house and ask for stove wire, get some of the slip on
    insulation for it too while you are there."

    Also get nickel plated high temperature crimp connectors for the
    stranded wire. Solid wire is for stationary wiring that doesn't
    vibrate, stranded for anything portable.

    I buy used industrial temperature controllers cheap at ham radio
    (general electrical) flea markets to use as thermostat replacements

    All I was interested in was seeing if it will melt lead . I have 2 varieties on hand , soft lead from old shower pans and lead pipe removed
    from old houses , other known relatively pure lead . I also have quite a
    bit of wheel weights cast into ingots . I do as you said , hard for
    cartridge arms and soft for balls and muzzle loader slugs , I've got a
    couple of type K thermocouples and a pretty good digital MM , I can
    verify the lead temp vs the 'stat setting next time I fire it up .

    As this shows, none of the plastic insulations can take molten lead temperature.
    https://www.omega.co.uk/temperature/z/wireinsulation.html

    You strip it or can let it melt off and bend the wires apart, as long as
    they don't short to each other before they enter the melt. Being shorted by the molten lead doesn't matter. The proof of that was a homework exercise,
    the voltage develops where the wires change temperature. https://www.meter-depot.com/blog/thermocouple-tip-contamination-with-other-metals-has-no-effect/

    The better way is to insulate them with ceramic beads or buy a metal probe. Omega charged me $30 to make a custom Inconel 600 probe. I don't trust cheap used stainless probes from flea markets in food, they might have been in
    lead or mercury.

    Wood stove cement or water glass keep the end of the glass braid from unraveling and will stabilize a winding of threads from fiberglass cloth. I made the water glass from lye and pool filter powder.

    I've measured (and felt) enough leakage through the insulation of old
    heating elements that I would be sure to ground the pot with a 3 wire cord. The highest Ohms range on a multimeter may not be enough to show AC leakage you can feel, I use a Megger that measures up to 1 GigOhm at 1000V.

    When I was young and had only woodworking machinery I cast lead salvaged
    from broken discarded batteries in wood ingot molds routed on the Shopsmith
    in vertical knee mill mode. The wood slowly charred and degraded and a
    plaster coating didn't hold up either so I had the bright idea of trying to cast under water since I knew molten copper poured into water would insulate itself in a stable steam bubble and briefly remain glowing.

    Lead also quietly filled a flooded mold cavity and hardened with a shiny unoxidized surface. I thought I was onto something until I poured into a cavity with a dimple in the bottom, an old nail hole that the lead flowed over. The resulting steam explosion plated the ceiling with a thin shiny layer. Luckily I wasn't in its path. After that close call I became more careful.

    Molten aluminum dribbled into a snowbank freezes into shiny teardrops with pointed tails.

    I found a few other cures on line, like bleach + ammonia which creates a poison gas. One good idea was to first cover the entrance with screening so they can't rush out.

    I was once attacked by wasps while sandblasting, and suitably protected. Apparently the sound of the air blast provoked them because they would try
    to rush the gun until the sand shredded their wings.

    The Google AI "knows" we are too dumb and incompetent to do anything like

    A drop of water in a lead pot can certainly be exciting, but at a much

    be worse because it sticks when it hits you.
