    shaded full face shield recommendation

    Commuter trains. The rings are heated during installation or removal to expand their diameter relative to the diameter of the gearbox quills that they grasp when at normal temperatures.

    shaded full face shield recommendation

    This is the unit I was looking at, how do you grab the headgear as opposed to the faceshield.

    There are a number of choices. Which one do you have?

    shaded full face shield recommendation

    I'm shopping for a full face shaded shield for use when I will be heating (no cutting or welding) steel rings with an oxy acetylene torch to be removed from a train's gearbox at my work. I don't want shaded goggles; I want a full face shield to protect from splatter as we heat the ring up...

    Shaw-Box

    This is the damaged one. I couldn't take a picture of the undamaged one because of the company's electronic device use policy. I'll contact Columbus McKinnon. The culture at my place of employment is so toxic that even if anyone remembered anything, they wouldn't say. If I asked management...

    Shaw-Box

    My employer has (2) different sized Shaw-Box blue wire rope cable hoists at the facility where I work, of which one is damaged. Each has a metal piece attached to the side of the block. The undamaged one has a horizontal leg which covers the top of the block and then terminates in a vertical...

    alloy for drill bit bushings (guides) .........

    Thanks for everyone's input, especially for the nitty gritty on quenching. "One of the commonest mistakes folks make is to just toss the part into a soup can of oil" probably would have described me.

    alloy for drill bit bushings (guides) .........

    Buying them is not a bad option except that the off the shelf versions aren't going to fit in the allowed spaces in all cases. Making something permits me to customize them to a situation specific holder, hence the desire to make them. In the case of the ones that were holding a cover on, an...

    alloy for drill bit bushings (guides) .........

    I'd like to turn sets of drill bushings (guides ?) for drilling holes in steel, stainless steel, or aluminum broken fasteners. I'd start with a very small hole and then move up in size as required. I'd size the guides so that they'd drop into the hole of the cover that the broken fastener held...

    Vapor blasting fails

    The term that I'm familiar with is Vapor Honing. The term is marketing hype. Vapor honing is a wet honing process as opposed to a dry honing process. I have both kinds of "blasters." Be advised that a pressure vessel based dry honer is not the same thing as a siphon style dry honer. Wet...

    Aluminum thread repair inserts

    I purchased a high temperature "thread locker and pipe sealant" through McMaster Carr to repair cast aluminum valve covers to avoid the cost of replacing them. The product is called Resbond 907TS Blue. The manufacturer's website is listed on the bottle is www.cotronics.com The temperature...

    vernier scale depth micrometer .0001" resolution...

    I'm working with two older machinists who insist on using depth micrometers WITHOUT a digital readout, and without a dial, so Vernier is all that's left as far as I know. The necessary measurement is part of the process to rebuild passenger rail car gear boxes on a commuter rail system, and...

    Pressure regulator for blast cabinet?

    Is your blast cabinet a siphon style blaster or does it use a pressure vessel?

    drill press mobile base

    Thanks for the compliment. The purpose of not welding it was to give me the flexibility of breaking it down and using the components on other pieces of equipment.

    24" x 48" granite surface plate AND wtb

    This size doesn't seem to be too common, though it would be a good size to put in my shop and have it double as a work surface with a cover on it. I want the surface plate for scraping. Is there anything off about a plate of this size? I've tried to work with someone on Facebook in...

    tool bit grinding wheel

    I have a Baldor 500 tool bit grinder which I've used a few times. It has a green grinding wheel which is very soft. While it works well, it generates a LOT of dust. It's now time to dress the wheel, which is going to make a mess. Short of winning the lottery and purchasing a diamond grit...
