    Cutting knife blanks from a sheet

    How do you guys go about cutting knife blanks (for stock removal) from a sheet? I have a Milwaukee Deep Cut portable band saw that I am to use for some cutting, but I don't think it will allow me to cut a strip from a sheet.

    If using an angle grinder with a cutoff wheel, does the cut generate a lot of heat so that might affect the straightness of the blank? The steel I have is oversize 5/32 52100. Pretty thick stuff.

    Thanks,

    Marko

    Never cut knife blanks but angle grinder with the hose running on the sheet gets me through 3/8 plate just fine...just know that you go through discs faster than you can change them.

    Diamond coated discs are available for angle grinders, I wonder how one of those would work?

    Care to elaborate?

    It's tedious , but drilling holes then playing connect the dots works for some .

    Duct tape the end of the hose so the water runs across the sheet of steel. I set this up outside clamped to a table. Use a carbide cutting wheel. This isn't something I do very often. Most of the time just the wheel w/o the water.

    Water and electricity don't mix...unless you're kinda stupid like me! The big thing is you're not cutting through a stream of water...you're using it as heat sink close to the cut.

    Yeah, I would love to get a rollnsaw, but not in the plans for a while. So, angle grinder with a cutoff wheel and clean up on a Milwaukee hand held band saw.

    I don't,
    Now I know that may not sound very helpful, but I just don't buy stock larger than I can cut with the tools I already have. I don't buy plate, I buy strip. The only real reason to buy plate is for waterjet cutting blanks, where the cost/benifit is on your side. On the other hand, if you got the material at substantial savings or it was the only way to get that thickness, than I understand. In that case, find a local fab shop with a shear. Tell them what you need and if they can do it. Shear to a width that you can cut blanks out of and you are all set. In a pinch call Aldo Bruno, I think he has a shear that can handle that stuff.
