    Acetone is a polar solvent like alcohol. It does not do a good job of dissolving hydrocarbons. The lacquer thinner would be better. Brake parts cleaner better. Even boiling lye solution would be...

    I need to buy those patterns. I'll make you a sweet deal on Crocker engines. However, you are going at this wrong. Date the wood in the patterns. Surely much cheaper and likely more accurate than the...

    Agreed, wrong wheel in every way. Get a vitrified wheel no finer than 46 grit. Itb sounds like this a traverse type surface grinder. If the surfaces are flat then a Blanchard would just the ticket.

    So you think one magnesium chip is representative of a flammable metal fire? One chip is not a problem. The extinguishers were not those of the extravagant claims by the OP. I will not jump through...

    Your memory sucks. The biggest difference was that the British used Whitworth profile threads which are a different angle regardless of the pitch. Canada used a mixture. The whole idea of the unified...

    You are a retard. NONE of the extinguishers in your links were the ridiculous crap originally claimed to be such a wonder. The "low pressure" extinguisher operated exactly as designed, which is to...

    You want a firing pin with twisted flutes? If you are thinking of the the non twisted shank, it is not hardened and usually not the high speed steel of the cutting edges.

    Maybe if you did a search you would find that the only references to this miracle are from it's manufacturer and Costco, who has made the mistake of marketing it. If you had ever seen a magnesium...

    Here's a better lesson: a vehicle, especially a pedestrian POS like a Chevy Van, fully involved, Is not worth the cost of a class D extinguisher. Protect exposures and be done with it.

    If the tool is an end mill then what the machine is called matters not, it's milling.

    I don't think that class D is one of those 3 major types. That would be stored pressure water, stored pressure dry chemical, and C02. The Class D are pretty much worthless. See here:Class D Stored...

    Wondering why anyone cares either way. The energy industry and most other heavy industry uses 8 UN for almost every thing 1 " and above. Occasionally 12 TPI for a fine thread.

    Uh, no. Fukashima ONE unit was to be decomissioned in one month. The others, as their life ran out. That was not the problem. The problem was that that the people who gave us the word Tsunami...
