    Chop saw jig for angle?

    I know I could just use pipe or tubing or channel, but I for some reason want to do this the hard way apparently. Has anyone rednecked a jig for a chop saw that allows angle material to be cut on its side instead of the usual way with the spine pointing up? The reason I want to do this is so the angle material can be cut on a diagonal with the spine being the longest edge of the three. I’m using this for a crawfish burner and would weld square plates to the cut edge as “feet”.

    I was thinking of using a large piece of angle laid on its side like an “L” and then welding a rest or stop in the vertical leg for the spine of the material I want to cut to brace against. This would allow the material I’m cutting to hold a perfect 45 degree “K” shape and allow the material to be cut at a side angle instead of a top-down angle.

    I know I can freehand it with an angle grinder but didn’t know if anyone had tried this type of cut with a chop saw.

    You can do it but you are going to eat blades. Chop saws work best when the blade is engaging a small amount of material. Cutting on the flat is very inefficient.

      Lay another piece of angle on the bed against the fence with the spine up. Then lay the piece to be cut against it with the spine facing away from you. That should hold your piece up where you can 45 it by adjusting the fence.....but it's going to be zero fun.

        This would be even less than normal. Imagine the angle turned to form a < instead of a ^

        The blade is only engaging one side at a time instead of both at the same time

          Lay one like ^ against the fence and clamp it down, then lay one against that piece like < and clamp it to the other piece.

            Didn’t think of clamping it. Thanks!

              Clamp it all good, and cut slow....if you bind it up on a 45 it's gonna get weird in a hurry and trash the blade.

                Check into the metal cutting blade that goes on a circular saw. They are a little pricey but they cut metal like it's butter.

                Never mind.

                  Yeah now that I think about it I am not sure where I’ll be able to clamp it. It has to clear the saw base before I can get a clamp on to both pieces. Hmmm. I will see what I come up with when I get home.

                        Lay it over a piece of square tube clamp the whole thing in your fence and make two cuts at 45 on the flat sides. As mentioned chop saws and flat stuff aren't buddies but as far as holding it in place you should be good

                          Here’s a video I did that describes it a little better

                            Does your chop saw have a vise type clamp? If so you can just vise it like this. I<I We do this on milling machines all the time. Just swing the vise to 45 degrees.
