Welding Gloves (2026 Update)

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 ?! :-).

The horsepower, pulley and belt design section of this may be useful to you:

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

Looked up Ozark on maps - good place to be by the look of it. Yes not a Harley "Monster"-Glide or a Honda "Lead"wing ;-)

Yes. Abandoned mine exploring is said to happen here... Not as I have met any who would take me along even if I wanted to...

---------------------- 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.
