    skill level

    I'm a novice at o/a cutting. A friend wants this:
    https://s-media-cache-ak0.pinimg.com...59c483827e.jpg

    Pretty sure I'd need to pick up a plasma cutter, but would I need a cnc table or would the right shoe or guide be enough? If a table isn't needed what skill level are we talking about? Could I get a couple extra sheets and put in XX hours of practice or is this a hire out job? I typically pick stuff up fast and my hands are steady after the first coffee, but I have no experience with something like this.

    Re: skill level

    Two easier options are to just use a cut off wheel and/or a circular saw. Draw the line and cut.
    With a cut off wheel or zip disc it might take 30 minutes and a dozen discs.
    You can buy blades from Diablo that cut metal and go on a standard circular saw. I spoke to them at a trade show last year and the 7-1/4 blades you buy at Home Depot are made just for that reason.
    Both those options will be fast and have virtually no clean up.
    A torch in a new hand will require a lot of clean up.

    The steel demon blade? Got one of those a while back, I was impressed. Thanks for the advice, don't know why I didn't think of that.

    Re: skill level

    Yes. That is the blade I was talking about.
    I would be careful about doing a plunge cut, but maybe use the zip disc to make the first part and then finish with the saw.
    Since the saw is larger in diameter, it will make it easier to cut straight lines.

    Re: skill level

    I picked up a 7*1/4 Admiral saw blade for my circular saw at Harbor Freight ,have made about half a dozen cuts with it on 1 x 1*1/2 x 1/8 steel tubing ,and it cut it great, straight ,and square. I believe it was 14.99. I got about 10 more cuts for this project out of 2 x2 x 3/16 , no reason why it won't cut them the same .

    I'll go along with what PSA says get a box of zip discs and mark you cuts out good.

    Looks like they handmade the hinge from pipe or similar...
    Also they used corten steel for that nice rusty look... but I see they tried to even it out by sanding unevenly...

    So what do you think about this door?

    The OP is being asked to do a job and has asked for advice on how to do it.

    Yes.
    Itís going to take one heck of a vertical support to keep that door level and square. Notice the brick wall thatís holding it.

    skill level

    Before I put something like this at someoneís house Iíd be asking them some questions.
    Will a youth/child be able to use it? How about a senior?
    Lots of folks enjoy the patina/rusted look. Will this dirty your clothing/hands when you use the door?

    I built a similar design fence for a customer probably about 15 years ago and then had to go out last summer and make some repairs so I took these pictures. I used 16 gauge sheets for the panels and fairly substantial posts when I built it first. Because the holes were large and square I just used my plasma cutter and then cleaned up the edges with a sanding disc. The narrow slots that you are looking for would be best done with either cutting discs or a steel saw blade but because the gate does not appear to be framed, I'm thinking you would need to use probably quarter inch thick steel in which case a 7-in grinder with a zip disc would be your best choice. It's hard to hang on to and keep straight but short of a laser or water jet I think it's the only way you're going to get that look.

    Order the panels from a cnc shop. Waterjet or plasma. Thank me later.

    Avoid plasma on the thin sheet or you'll have other issues unless you can have them cut it underwater...
