    i know i can't with a wood saw blade, but what if i use a blade for steel? or do wood band saws run at too fast a rate? i really want to get a saw, and thought this would be and easier cheaper way.

    just change to a metal blade.watch the fingers cuts 16gauge metal real easy.we have one in the sheet metal shop at work used every day.
     
  3. yes, you can....but you have to put in a metal blade , and SLOW the speed down...your wood bandsaw probabilly has a speed of 3000 feet per minute...you would need to slow it to 150-300 feet per minute

    you would have to adapt some sort jackshaft/pulleys/speed reducer gearbox, etc,.to get to the right speed

    For some of the Sears Craftsman band saws they sell a gear reduction device to slow down the speed so that it is easier to use it to cut metal (with a metal blade abviously).

    A long time ago I had a meat saw that I changed over to cut metal. I used a Crosley (I think) transmission to slow the speed down. Worked pretty good.
     
  8. For thin guage,(up to 20) just change the blade to metalcutting. After that, you better slow down the blade speed a lot.

    You can weld wood OK though, you need Hickory rod and use Peanut Butter for flux! [​IMG]

  11. And don't forget to clear ALL the wood dust and shavings
    out of the housing otherwise they may ignite. [​IMG]

    thanks for the input guys. i know i'd have to change blades, and figured i'd have to figure out how to slow the sucker way down. i need to be able to cut some fairly thick plate.(3/16 - 1/4)

    sounds like i should probably just track down a saw designed for metal.

    where have you all found yours, and what did you pay for em?

    I have tryed and did not work out well. Could not get blade speed slow enought. Best solution? Can you say Miwaukee porta-band,it kicks ass.
     
  14. Just make sure its really clean

    Does anyone know of an actual metal band saw, if so who makes it. Or is slowing down a wood one the only option?
     
  16. I think General still makes a metal cutting band saw.
    Grizzly might have one.

    Most are industrial machines,and priced accordingly.

    Could you change one of the pulley sizes to slow it down enough?

    Ian and Flatdog said it best; "If your going to cut steel, use the right tool."
    If your going to do a lot of cutting (steel) consider a "metal bandsaw" type cut-off saw that allows the blade assembly to stand vertically and be used for cutting odd shapes.

    Wood bandsaws run at too high a speed. Even just changing to a metal cutting blades will eat blades up fast if your cutting anything thicker than 20 ga. aluminum.

    (but then again I sell bandsaw blades [​IMG] )

    You need to drop from 3600 RPM to 1800 RPM OR LESS (blade speed equates to thickness, hardness and feed speed)

    Short of an industrial speed reducer you couldn't fit enough reducer pullies under the bandsaw. (the speed reducers are worth more than the bandsaw)

    Sell a lot of metal bandsaws after people have played around trying to get a wood bandsaw to work!!

    I might be out on my own on this, but angle grinders and discs are quite cheap these days, I have not used my metal band saw for quite a while. Just use the grinder. I spose I'd use it if fabricating a frame or something, but just for hacking out little brackets etc, the grinder is quicker and simpler.

    It would also depend on how much power you have. I bought a wood bandsaw a couple years ago, a 14 incher. I got the biggest motor available, I think it's 1 1/2 HP, so I could use it for metal. You need the power to back it up too.

    Before I had this I made an aluminum 3" thick master cylinder spacer. I bought a metal blade and used my uncle's wood bandsaw. I needed to go really slow and stop alot to let it cool, and kept a bucket of water handy. It took a while but it came out good.

    My shopsmith tool has a variable speed pully on it and is slow enough, but I haven't been able to find a metal cutting blade for it yet. Anybody know a source?

    Try to find a "BI-METAL" blade. They're worth the extra cost.

    I've wondered about this, too--I think I remember the guys at Sears (their tool buyers, not the chimps behind the counter) telling me the metal saws go 23 or 33 percent slower...I don't exactly remember the numbers. Sears does sell a two-speed bandsaw for wood and metal.

    However, I agree with changing the pulleys--I'm tired, so I don't remember which way it would have to go, but if you change the pulley on both the motor shaft and the saw wheel, it'd slow it down. A smaller wheel on the motor, and a much larger wheel on the saw?
    I know the math is out there. Again, I'm tired, but I think if you took the RPM of the motor and figured the diameter of the drive pulley off the motor shaft, and then figured the diameter of the pulley on the bandsaw wheel, that'd get you started. Knowing the FPS of the saw currently would also be a good number to know.
    Or, look in a Sears catalog and see what pulleys are on that two-speed saw.

    Who sells these two brands? I don't remember seeing them at Lowes or the Depot.
