    Need to cut some 3/16" welded steel for underside of rear seat brackets. Never used a metal cutting chop saw before. I have a 14" metal cutting blade. Do I need to use cutting oil? And are the considerable sparks that fly out capable of starting massive fires or does it look worse than it is? /forums/images/graemlins/eek.gif

    TIA /forums/images/graemlins/ears.gif

    oil bad juju...just start cuttin...the only time you would need oil would be say on a sawzall or band saw ...chop saws are abrasives so its just like a grinder...when ya start throwin sparks it leaves the chance of a fire /forums/images/graemlins/eek.gif /forums/images/graemlins/thumb.gif

    OK on the oil part.

    Is it supposed to throw a lot of sparks? Can't see how it wouldn't...

    Lots of sparks is good.....just watch where they go. They can light something on fire. /forums/images/graemlins/1zhelp.gif

    Lots of sparks and LOTS of noise. Make sure you wear safety glasses and hearing protection. Just make sure that you position your body to the side of the saw when you start cutting.......Ask me how I know!!! /forums/images/graemlins/tongue.gif /forums/images/graemlins/rolleyes.gif

    The sparks that fly from the steel lose their heat pretty quickly. They would have to come into contact with something relatively flammable very quickly after leaving the saw for a fire to start.

    Thanks guys. I went out there for a minute to start to cut and decided to learn to duck and cover as my first skill. And maybe pull the whole thing outside and point the sparks towards the garage door that I've previously covered with roll roofing!! /forums/images/graemlins/thumb.gif

    Anybody got an asbestos suit?? /forums/images/graemlins/eek.gif /forums/images/graemlins/eek.gif

    as long as it has a standard abrasive blade don't use any kind of cutting oil.
    If it is a blade that has teeth on it then yes use oil

    Ya might want to wear a long sleeve shirt and a hat too. I wear one just because I like what little hair I have left /forums/images/graemlins/eek.gif It makes short work of cutting stuff though. /forums/images/graemlins/thumb.gif

    Those sparks will catch something on fire. The heat from each tiny particle of red hot steel adds up quick. Most places where I've used chop saws have some sort of thin sheet steel deflector behind the saw to direct the sparks somewhat downwards and away from the operator.

    Watch the edge of the cut when you're done too. Number one it will be hotter than hell, number two is there will be a burr along the edge that will open you up if you're not wearing good gloves. Long sleeves for sure, hearing protection for sure and a full face shield. Also make sure the work is clamped good...if it starts to move around mid-cut the blade may jam and that can get ugly.

    Have fun!!!/forums/images/graemlins/grin.gif

    OK, I did it! Wrapped myself up in long gloves, face shield, ear plugs, fire suit (no, just kidding). Cut the pieces, got out the grinder and smoothed the edges, drilled out holes for the bolts. All I have to do now is paint 'em.

    And didn't catch anything on fire (tho I believe that was just beginner's luck).

    Only weird thing was that it seems like the blade doesn't cut 90 degrees, it cut on a bit of a slant. Thot I adjusted the fence right, but either I didn't or this thing is just a POS.

    After a while I kinda liked the sparks... one of my friends suggested that we strap me to the front of his boat and have our own fireworks display next year in Ventura. Hmmmm. /forums/images/graemlins/cool.gif

    Thanks for all the help guys! /forums/images/graemlins/thumb.gif

    Hey Michael, thanks for lookin out for me.

    I didn't spray anything on the blades. Once I understood that the cutting wheel was really an abrasive blade and does not work like a traditional wood cutting blade (or a sawzall blade) I also realized that putting something on the blade could cut it's efficacy if nothing else.

    I just wrapped myself all up in non-flammabe stuff and cut away (kept a fire extinguisher close by, just in case I lit the house on fire or something). All went well. /forums/images/graemlins/thumb.gif
