    Yes, actually you are able to use a CNC machine. However, please understand a person who creates our logo free hand will get more consideration since it is a lot harder to create.

    However, we currently have several people who are attempting to cut with a CNC table using our WeldMax series and WeldPro series plasma cutters.

    Shouldn't someone that has the ability to convert your .jpg logo to machine language get extra credit

    Is a "Virtual Logo" any help?

    Won't be entering this one. No Hand Plasma or Torch. Hot Rodding it with A 6010 dipped in water just won't give the results you would like.

    I see... we will have other contests shortly in addition to this one. Perhaps in the future you may have the resources and the time.

    The rules do not specify what cutting method(s) can be used or what metal or thickness it has to be cut from.

    According to the rules, you could cut it from aluminum foil with a pair of scissors. You could also cut it from thin gauge sheet (like that galvanized ducting material sold at Lowes, Home Depot, and others) with a Dremel or other abrasive tool. Some have also had luck cutting sheet steel/aluminum with a saber/scroll (reciprocating) saw.

    I am sorry. You are right. Please make sure the thickness of the metal is near 1/4 inch. If you are cutting aluminum, please make sure the thickness is not bendable. We prefer something near 1/4 inch.

    This will be displayed in the office!

    Thanks for the heads up!

    What? You're joking, right? Nearly half-way through the contest you decide to change the rules?

    By applying that high of a minimum thickness rule you are totally stifling the creativity of your contestants. As well significantly reducing the number of people that are capable of competing.

    What if Johnny Highschoolstudent really wants a plasma/welding setup, but all he can afford from the money he makes on his paper route is a Dremel and a piece of 18 Gauge steel? Are you really going to totally crush his hopes by restricting the contest to those who already own the equipment capable of cutting 1/4 steel?

    And what do you mean "not bendable"? Just about anything is bendable if you apply enough force.

    My previous post was not intended to point out any sort flaw in the rules due to non-specifics. It was to encourage more participation by pointing out how open and fair they were for everyone, regardless of their current equipment situation.

    If you leave the rules open, like they were before, you might not end up with a winning entry that is exactly like you imagined; you will probably end up with something even better.

    Tensaiteki,

    Everyone is welcomed to the contest! In fact, if you submit a thin piece of material but the quality of the work is better than someone who cuts out a rougher looking cut from something thicker, you chances of winning are higher. of course.

    Please understand, we will have numerous submissions. All i was implying was if someone was to submit the perfect thickness and the perfect cut, they would have a better chance of winning. Now, i agree these rules should have been implemented before the post, but this is our first contest and I am learning as we go.

    However, we will first view the submissions on this site via pictures of the work and people will have a chance to relate their likes and dislikes of the finished Longevity logo. Ultimately, it will be up to our staff and dealers to decide the winner, but we will take the welder's input on this forum and the Longevity forum seriously.

    We want everyone to participate and someone who does the best job will win both the WeldMax LC-520D and the $500.00 cash prize!

    i just reread this whole thing and realized that no particular material is speced. could someone submit wood or plastic or perhaps someone with a computerized vinyl sign cutter setup could ace this thing. Doesn't say much for skills or workmanship.

    As long as you are cutting metal, whether it be aluminum or steel, we have no requirement. The workmanship and the quality of the cut will be determined on this forum and by our staff once we receive the finished product via a return tracking label.

    We are giving the people who cut the logo free hand more recognition and consideration!

    I read in one of the post responses that ALUMINUM should not be bent. Does this rule apply to all metals that are to be entered? I understand that this will be displayed at your facility- (on a wall or flat surface?)- the mounting orientation will mean a great deal in determining the design.Also, I have not seen anything related to a puzzle style logo-is this acceptable?

    We prefer a design that is thicker similar to the 3d image presented by Gaustin

    http://weldingdata.com/WelderReviews...longevity.html

    However, we welcome all cut outs. As stated before, if your cut out is the best presented, you will the contest. However, please understand, we would like a ticker piece of metal that has the cleanest cut.

    At this time, we wish to display it on the wall at our office - however, that will not determine the winner. We want a nice logo cut and size.

    You also mentioned a puzzle style logo. Please clarify or give me a sample.

    If there are any other questions, please feel free to ask.

    Thanks

    Unfortunately, we are hoping to see the logo cut with a plasma cutter.

    Longevity Plasma Cutter and Welder Giveaway Plus $500 cash prize!

    I realize that many here have strong opinions on Longevity and the other import people, but please, this thread is not intended to promote any particular brand of anything so please try not to turn it into another bash-the-China-machines-thread.

    The purpose of this thread is so I can share the methods I use to accurately cut shapes out of sheet metal without a CNC machine or making stencils and the like, just by using simple tools and methods that are easily available.

    Anyway, the project I will be using to demonstrate these methods is the Longevity logo I made for the Longevity logo contest.

    (Click all pictures for larger versions)

    I started with a piece of 16 ga. steel measuring approx. 13" X 32":
    http://www.tensaiteki.com/images/sto...heet_small.jpg

    I then traced an image of the Longevity logo in a CAD program and offset lines for the kerf as well as the width of the tip of my plasma cutter and printed it off. I printed this one off on a inkjet plotter but any sort of printer will work (inkjet, Laser, etc.). The pattern does not have to fit all on the same sheet of paper, multiple sheets can be used and simply taped or glued together.

    To glue down the paper, I first position it on the steel and weight down one half of the paper. Then I lift up the unweighted half and spray with 3M Super 77 spray adhesive (available at Wal-Mart).

    http://www.tensaiteki.com/images/sto...half_small.jpg

    After the first half is glued down, I remove the weights, lift the other half and apply more glue. Using this method you can accurately position the template without having to try and get a lose piece of paper aligned on a sticky surface.

    http://www.tensaiteki.com/images/sto...lued_small.jpg

    Here is a close up of the paper template. The solid lines show where the kerf (material burned away by the plasma cutter) will be. The broken lines mark the width of the tip of the cutter.

    http://www.tensaiteki.com/images/sto...acro_small.jpg

    For all the straight cuts I use a regular steel framing square as a guide. I just line the edge of the straightedge directly on the broken lines (the square is actually directly above the broken lines, the camera angle and the warp of my heavily used square make it look like it isn't.):

    http://www.tensaiteki.com/images/sto...acro_small.jpg


    My plasma cutter does not have a pilot arc, only a high-frequency start. The high frequency usually cannot start an arc through the paper so I just take a pocket knife and cut a small hole in the paper to expose bare metal. This is only necessary when starting a new cut, If I am starting from an existing cut this is not needed. If your plasma cutter has a pilot-arc this is not necessary at all.

    http://www.tensaiteki.com/images/sto...spot_small.jpg

    I always position myself so I can drag the torch toward me. I simply drag the torch like a box cutter on the surface of the work piece. Even without a special drag-cup on the torch, dragging at sheet-metal amperage should not damage the cutter.


    http://www.tensaiteki.com/images/sto...cut1_small.jpg

    Then I re-position the square for the next cut:

    http://www.tensaiteki.com/images/sto...cut2_small.jpg

    By positioning both "legs" of the square on the offset marks and cutting into (towards) the corner of the square you can ensure that you stop the cut exactly were you want to.

    Re: How I do accurate plasma cutting (demo'd using Longevity logo contest entry)

    (Continued...)

    Simply continue to reposition, cut, repeat until everything is cut.

    http://www.tensaiteki.com/images/sto...most_small.jpg

    Well, almost everything..:

    http://www.tensaiteki.com/images/sto...done_small.jpg

    The framing square works great for straight cuts, but what about curves like the 'O' and 'G'?

    You could make a stencil-type thing out of thin plywood or some such material, but that's a lot of extra work (and expense) and in the end, you have a bunch of useless stencils that you either have to throw away or store until the day that you might need them again.

    However, I found another way. While wandering the aisles of the local Hobby Lobby (hobby supply chain) I found a drawing tool called a flexible artist's curve. It's a rubberized doohicky that you can bend into any shape and it will hold with very little spring-back (I think it's just a bar of lead on the inside). All you have to do is bend it to the shape of the curve you want to cut and use it just like the steel straightedge.

    http://www.tensaiteki.com/images/sto...urve_small.jpg

    Even though it's coated in a sort of rubberized-plastic material, I don't have any problems with it burning or melting because I only use short sections at a time and use different parts of the curve so no one spot gets too hot.

    http://www.tensaiteki.com/images/sto..._cut_small.jpg

    After everything is cut out, the workpiece is usually warm enough that what remains of the paper will simply peel off:

    http://www.tensaiteki.com/images/sto..._cut_small.jpg

    The glue will leave a residue on the metal which will interfere with welding so after removing the slag I wash them off in a solution of water and a citrus-based cleaner called "Goo-Gone." After rinsing with water and drying they are ready to weld. I found that cleaning with this method makes using acetone unnecessary. The Goo-Gone solution is nowhere near as smelly, flammable, or toxic as acetone:


    http://www.tensaiteki.com/images/sto...lean_small.jpg

    I then cut a bunch of 7/8" wide strips of the same 16 ga. material and bent and welded (picture only shows tacks) it around the edges of the letters:

    http://www.tensaiteki.com/images/sto...lded_small.jpg

    Then I welded all the letters back onto the original piece:

    http://www.tensaiteki.com/images/sto...aint_small.jpg

    Finally I painted it (the white was sprayed, the red and black were hand-painted):

    http://www.tensaiteki.com/images/sto...nted_small.jpg

    And that, ladies and gentlemen, is how I do things.

    This post makes me want a plasma cutter that much more... thanks! LOL
    Very nice! I like the square tip - I'm so shaky most of the time it looks like I'm cutting out halloween graphics for the kids...

    Wow! Very nice work! I will be sending you and the two other people who have emailed me contest entries a DHL return label so we can analyze the work here in the office.

    I have all contact information. Thanks for joining the contest. We will pick a winner here shortly once all the contestants turned in their Longevity Logos!

    Thanks,

    Nice tutorial! Great work.


    I started to build an entry myself. I felt like it was cheating, for a professional custom sign builder with access to a shop full of great tools to enter. So I didn't, but I did go as far as tracing the logo in CAD like you did.

    I was going to do pretty much the same thing you did, actually. Only a little bigger, using 1/4" plate and 1/8" thick 3"wide returns. Returns are what we call the 7/8" strips you used.
