    Default OT?:Air powered skil saw

    I saw a air powered circular saw today at a thrift store. looked well made. Made in USA all heavy Al castings. I suppose it would not spark at motor brushes but sawdust and static might still be a fire hazard. I guess it would work underwater. But who needs one. At a guess made in the 1960's or earlier.

    PS: looked like a 7 1/4" blade as a guess. 3/4" supply reduced down to 1/2' pipe. must use a lot of air!

    Hilarious typo, where the shift key makes a 12:1 difference in a number.

    I wish I could get one of them. Very handy for use when it is raining, much safer than electric tools.

    Go to Amish country. They have factories full of nothing but air powered table saws, planers, etc.

    I think that air powered saws are used more for construction work. Like cutting shoring for after digging a hole. This is where they would have an air compressor, say for jack hammers but no electric or generator around. The saws I have seen had the same twist connector as the jack hammers use.

    Bigger air tools gobble up air and a very inefficient. I had a good sized angle grinder that a 5hp quincy could not keep up with. It had about the same power as a big Milwaukee electric grinder. Air compressor 5 hp on three phase, or Milwaukee on less than 15 amp 120 volt...

    I have seen those, like above they must hog air like mad.
    Air tools are super ineffecient but if you need lots of power in a small space then they are hard to beat.
