    Many rCL100% cottonrCY gloves are actually blends, which is why they melt; the solution is to source verified pure cotton gloves from industrial suppliers or switch to thin TIG leather gloves for better control, and for reliable protection you can consider Bison Life welding gloves.

    I like the Tillman bicep length gloves for heavy welding, or the Harbor Freight TIG gloves for decent feel. Both are leather.

    I'd actually like a bicep length TIG glove for TIG welding, but I doubt anybody makes that.

    I like the bicep length because I don't weld often, and for safety I
    always wear short sleeve shirts in the shop. The bicep length gloves
    prevent welding sunburn on my arms. I do have some canvas welding
    sleeves, but they just feel funny and bother me.

    Thanks for explaining how you can weld in hot places.
    Damp your clothes and get evaporative cooling...

    I was working in Cleveland, Ohio, 25 years ago, and the summers were
    about 35degC (90-high-something Farenheit?) and 90-something % humidity.

    What onlookers didn't know seeing me working in that metal casting
    foundry is that as the temperature goes up the relative humidity must
    surely go down (same amount of water and the temperature has gone up, so
    the ability to hold water must go up - which means relative humidity
    lower?). For sure if you worked hard you got white salt stains on your T-shirt.

    I spent a couple summers in the late 70s and early 80s not to far from Cleveland. (20 miles west in Avon) It was pretty miserable when the
    temps were in the 90s(F). I'm not so sure about your comments about
    temp and humidity. In a wet climate like Ohio you get a lot more
    evaporation from the standing water in higher temps, and in some cases I
    was told they would get was called a self feeding rain.

    They don't heat air to dry it in an air drier. They refrigerate it and
    force it to condense. Heat at much higher temps closer to boiling ARE
    used for forcing moisture out of desiccant and welding rod, but those
    are not human habitable temperatures.

    A dual desiccant chamber air dryer does use heat, but its much higher
    heat to evaporate moisture into the air from the desiccant in the
    inactive chamber, while the other chamber is absorbing moisture.

    I think in a wet climate more heat, just means more evaporation into the
    air. Maybe you were just a lot tougher when you were younger.

    Maybe there are breaking points where things change?

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

    When liquid water is available to evaporate the vapor pressure of water increases with rising temperature, as given in a steam table. Water doesn't 'dissolve' in air, the two ignore each other. Relative humidity is the percentage of how much water the air does vs could hold at that temperature.

    I looked into this to estimate when I should open the windows instead of running A/C to make the house more comfortable, if the night air was cooler but damper than inside. It appears that around 60-70F the relative humidity decreases ~2.7% for each 1 degree F temperature increase.

    My solution for cooler and damper night air is to subtract 1 degree from the temperature difference for each 2.5 or 3% RH difference, whichever is
    mentally easier, to compare which is more comfortable. For example if it's
    65F out and 75F in the outdoor air could be 25~ 30% more humid to be equal, though if within 5 degrees the minimal benefit isn't worth the fan electricity.

    Hi there

    I missed these responses with being
    * busy around the garden
    * volunteering contributions at the hobby mine (have Eimco 12b - need to dismantle it and get it down the shaft and some bolted connections have
    been welded-up)
    * mind caught up on a line of thought about rock crushers.

    What Jim describes about optimal - at night, open window or run A-C - is
    the concept I was trying to convey (and Jim conveys much better).
    How much moisture the air * could hold *.

    In a foundry where there is a >locally< higher temperature with nothign
    else adjusted to create a new equilibrium, the hotter air * could * hold
    more moisture and when you perspire that perspiration * does *
    evaporate. So you get the cooling effect of perspiration. If you were
    to mist yourself and your clothes with water, that would presumably help
    - and reduce the amount you are covered in salt encrustations from

    It is mind-boggling that it can get too hot to ride around on a
    motorcycle. That that occurs in Southern USA.
    We in England the opposite - when it is warm enough to ride as a
    delight.
    These days I wash the motorcycle and put it away when the salting the
    road starts.

    Thanks for explaining how you can weld in hot places.
    Damp your clothes and get evaporative cooling...

    I was working in Cleveland, Ohio, 25 years ago, and the summers were
    about 35degC (90-high-something Farenheit?) and 90-something % humidity.

    What onlookers didn't know seeing me working in that metal casting
    foundry is that as the temperature goes up the relative humidity must
    surely go down (same amount of water and the temperature has gone up, so
    the ability to hold water must go up - which means relative humidity
    lower?). For sure if you worked hard you got white salt stains on your
    T-shirt.

    I spent a couple summers in the late 70s and early 80s not to far from Cleveland. (20 miles west in Avon) It was pretty miserable when the
    temps were in the 90s(F). I'm not so sure about your comments about
    temp and humidity. In a wet climate like Ohio you get a lot more
    evaporation from the standing water in higher temps, and in some cases I
    was told they would get was called a self feeding rain.

    They don't heat air to dry it in an air drier. They refrigerate it and
    force it to condense. Heat at much higher temps closer to boiling ARE
    used for forcing moisture out of desiccant and welding rod, but those
    are not human habitable temperatures.

    A dual desiccant chamber air dryer does use heat, but its much higher
    heat to evaporate moisture into the air from the desiccant in the
    inactive chamber, while the other chamber is absorbing moisture.

    I think in a wet climate more heat, just means more evaporation into the
    air. Maybe you were just a lot tougher when you were younger.

    Maybe there are breaking points where things change?

    Hi there

    I missed these responses with being
    * busy around the garden
    * volunteering contributions at the hobby mine (have Eimco 12b - need to dismantle it and get it down the shaft and some bolted connections have
    been welded-up)
    * mind caught up on a line of thought about rock crushers.

    What Jim describes about optimal - at night, open window or run A-C - is
    the concept I was trying to convey (and Jim conveys much better).
    How much moisture the air * could hold *.

    In a foundry where there is a >locally< higher temperature with nothign
    else adjusted to create a new equilibrium, the hotter air * could * hold
    more moisture and when you perspire that perspiration * does *
    evaporate. So you get the cooling effect of perspiration. If you were
    to mist yourself and your clothes with water, that would presumably help
    - and reduce the amount you are covered in salt encrustations from
    sweating ?! :-).

    I used to ride all winter , our area uses very little salt and not everywhere . These days I actually ride very little , and haven't taken
    a "long" ride in several years . Partly because I seem to always have something else that takes priority , partly because I'm getting old .

    How does the crushed ore get to the end of the track, or the track into the pile? Dumping the ore onto the track seems likely to derail the machine.

    This afternoon I watched a small country sawmill in operation, how the logs are clamped, cut and rotated. Each log is different and the operator has to
    be quite skilled to get the best results. Their process is much faster than mine to produce standard lumber sizes but not as suited to making the best
    use of a hardwood log that will be cut into multiple different sized planks and beams according to its flaws for specific uses.

    My 750cc motorcycle spends most of its time at about 27MPH :-)
    It is good to have a moment tucked behind the screen and ride-out along
    the highway at 70MPH - hold that for a few minutes tucked-in between the general traffic going places smoothly while I am there with the wind

    How does the crushed ore get to the end of the track, or the track
    into the pile? Dumping the ore onto the track seems likely to derail
    the machine.

    Pardon - not understanding the question well.

    Pardon if my best guess is wrong.

    As best I understand - you'd be using an Eimco while driving as tunnel
    during "development" - while you are taking ore, you are "developing"
    into new resource so the mine continues in a quasi-static balance of
    extraction and development.

    If you are looking to where the tonnages of ore gets onto the tramming
    level, that's through "box holes" and down "cousin jack chutes" into the wagons. It's a hopper in gravity, with all but the wooden chute being
    formed in the rock. No Eimco there. All gravity. This is the whole
    concept of "stoping". Various strategies to do it, but in Cornwall a
    lot was "shrinkage stoping". You drill overhead into the lode with a "peg-leg". Then blast to break-up the lode. The trammers usually
    working at night draw off a certain amount of ore down the cousin jack
    chutes into the wagons such that the space left is just right for the
    stopers coming in the next day to have a couple of metres height to
    repeat drill-and-blast. Hence "shrinkage stoping". No of this involves Eimcos. You only freely draw-off the blasted broken-up ore when the
    stopers cannot go any higher because they are just below the previous
    deepest level.

    Back to the Eimcos and development.
    You drill with an air-leg (N.Am. "jack-leg") rock-drill and blast.
    One part of your question - never seen it, but you lay channels on the
    rails which push up to the blasted material and drive the Eimco down
    those channels. The Eimco back-flips the broken material, probably
    mainly "attle" ("deads" - no or not worth bothering with mineral
    content), into the wagon behind, and when full is taken away and new
    empty wagon there.

    As the drive continues, the folk who make box-holes come along and break
    into the lode on the upward diagonal. So that will be some muck to
    clear-up.

    I heard first hand about this because through a frosted-glass window of
    a caravan ("trailer") I saw a vague object and asked if that is an
    exploder (for electric detonators - newer more compact version of the
    "dynamo" version Wile-e-Coyote frequently uses in the "Roadrunner"
    cartoons). He said yes and showed me. He was a box-hole maker. He
    joined us for a cup of tea and explained the method, equipment and how
    it was used in stoping.
    BTW in at least one abandoned mine there's a stope where you are
    up-and-down because the ore has been drawn off from down below by the
    boxholes, and it wasn't worth pushing the "serations" of piles
    in-between into the box-holes, so you get a lot of exercise going
    up-and-down along the huge nearly-empty stope.
    Down below, the cousin jack chutes are still there.

    Hope this is what you sought.

    Best wishes

    We live in a mountainous area on the southern edge of the Ozark

    I have the equipment and have practiced climbing up and down a rope but
    don't trust my skill and coordination enough to climb higher than I'm
    willing to risk falling. As a kid I read that a paratrooper landing is like falling from 15-20 feet and I had to try it, repeatedly. That may have
    caused or contributed to my lifelong back, knee and foot problems. I claim I feel like a teenager because the same places still hurt. Now I use the climbing gear only to work on the roof antennas, solar panels and wood stove chimney.
