    I got a length of 10mm x 25mm flat steel bar and wanted to cut it into 20mm pieces.
    I need quite a few so set up my big evolution chop saw and made a stop block our of wood at the right hand side 20mm from the blade.
    I thought I could feed the metal in chopping 20mm pieces off the length.
    First piece was fine; next piece must of caught the blade after it had cut through and shot off like a bullet somewhere into my workshop!
    How can I cut 20mm pieces off a length without having a 20mm x 25mm piece of steel bar embedded into my forehead?

    Bandsaw would be far safer.

    Don’t use a stopblock. I don’t work metal but I know not to do this on a timber chop saw with short cuts, they get trapped between block and blade and get flung out.
    You’ll just have to mark it up, or setup a stop that flips out the way before you cut

    If they don't have to be hyper accurate you could draw a line on the saw baseplate and use that as a guide.

    Is it possible to clamp down the 20mm section to be cut off with say a 15mm timber batten and clamp the batten to whatever the chop saw is sitting on ?

    Realise the blade and guard has to clear the batten but may just be enough space ?

    Not with a piece of flat steel bar, shot from a chop saw, anyway............ Be safe.

    If the 20mm pieces can be near enough not precisely 20mm then apart from a hacksaw already mentioned you could use a reciprocating saw with metal cutting blade, that will piddle through it.

    If you need them to be accurate, use a stop block ,along with a removable distance piece between the block and the end of the steel bar to give you the correct length.
    Set them up together to cut 20 mm ,cut about half way through and then remove the distance piece and complete the cut.The cut piece will fall cleanly .
    repeat as required.
    You can make the DP as long as you like so that it is easily shifted .
    It works with wood as well as metal. I have used this method to cut plastic.

    Apologies Phil. I just noticed that you had suggested something similar. Definitely the safe and accurate way to do it.
