Thread: Cutting knife blanks from a sheet

  1. #11
    I have a HF 4x6 that cost me all of $180 with their sale and a coupon. You can set it vertically and put a work table on it turning it into a vertical band saw which is something not really clear or at least wasn't to me until I saw one in the store. Works good, but cutting metal with a bandsaw is tediously slow. An angle grinder is faster but not nearly as accurate and throws sparks all over the place and makes the steel red hot and throws tiny shards of steel all over and is generally far more not good IMHO. I started with the angle grinder, but quickly bought the metal cutting bandsaw and am far happier with it.

    Damn, that is where I go the steel from. Should have asked him to shear it.

    Is there any risk to cut the blank with a grinder? Heat build up, warping, etc?

    Any of you guys use Milwaukee hand held band saw mounted vertically? I think I saw it in Stefan's video.
    I have one but need to build a custom table for it.

    There is a guy that makes stands for the Milwaukee band saw that look real nice and aren't too spendy.

    Cutting strips with a shear is more likely to give you warping than any angle grinder could produce.

    I have an angle grinder in my right hand and a spray bottle to keep things cool in my left hand.A welding jacket is a must unless you want to put holes in your cloths.

    Speaking of that kind of thing, I don't wear anything but cotton when I'm working with things that make sparks.

    I have a 46" welder's leather apron (inspired by Bob Kramer video, though he has a blacksmith apron ). It comes very handy in metal working as well as wood working.

    I am mostly concerned about whether I need to normalize steel after cutting out the blank.This is a thick steel, so there will be heat created by cutting and possible warping.

    Looks pretty good (the table for Milwaukee) Adam. I might get one after all.

    Not a giant stomp shear. Handheld shears on thin sheet metal yes, but a stomp shear or break will cut them cleanly.

    Know anyone with a plasma cutter? Cut it 3/16" over-sized and grind out the heated zone. Shouldn't warp much. Plan on doing more of these? Definitely water/laser cut next time. Or get your own Plasma cutter. I use mine a lot.
