    Infinity cube table, a stunning to look at, nice little beginners-improvers welding project.

    Only Basic tools would be required and a stick or mig welder capable of doing 3mm thick and it is perfect as a mild steel box section project: 30 x 30 x 3 or 40 x 40 3, maybe even 1½" x 1½" X 14 gauge ERW.

    'er-indoors has asked for one, but it is way down my list of priorities!

    A smaller version out of, say, 20mm box would make an interesting plant stand. Could be a project for my local Men's Shed.

    I can see someone deciding to sit on that, resulting in a mess of bent tubes. :doh:

    Fill them with concrete or make them out of stock bar.

    I'll be making a 6" version out of 12mm square bar as a table ornament pretty soon. It took this old brain a while and a couple of videos to figure it out but it's a total of 18 pieces with 12 the same length, 3 with one of the mitres rotated clockwise thru' 90 deg. and 3 with the mitres rotated anti-clockwise thru' 90 deg. For the shorter pieces, subtract the width of the material being used plus the gap you want. So for mine with a 15mm gap: 12 pieces at 150mm and, 6 pieces less the width (12mm) and less the gap (15mm ) which comes to 123mm.

    As an aid, I used MS Paint to create an exploded view diagram. The 'S' denotes the shorter pieces of steel. Hope it makes sense

    Here's a pic of the original for reference.

    Next on the list - all 45 deg. angles?

    CAnt remeber, I asked a few months back for a cutting list a a good forumite sent them through, worked a treat for me. At least it gives a starting point for your cutting list.

    I made one a couple of years ago: https://www.mig-welding.co.uk/forum/posts/1184767/

    It was discussed on another posts somewhere subsequent to that, with drawings too, but I can't find it...

    EDIT: Found it - it was you @Lazurus that started it!

    If anyone is considering making a cube, here's a few photos showing the approach I took. Basically I worked in pairs fully welding each time and didn't have any real problems with distortion. It also made it easier to grind and file off - no damage to the hands or working with a grinder at awkward angles.

    These two pieces came first. They're identical, just need to remember, one above - one below.

    Which led to this - oriented to show the way they'll finally fit together.

    The last two welds. One joint bottom left and the mole grips supporting the top joint before welding. The block behind the cube which weighs around 16lbs was used to weight down the lower joint once it was set up for welding.

    And finally.

    The blocks on which the cube is stood provided a flat surface so all I had to worry about was keeping things square horizontally and vertically. I didn't keep a strict eye on the time but I reckon the job took just over 7 hours excluding thinking time.

    Here is a vid of it done out of a single piece to get the radius corners.

    Is it chrome in the start post? I think that radius corners aren't real for beginners. Also, it is need a metal cutting machine for right 90 degrees corners.

    Looks like he painted the chrome on with an angle brush.

    Stick-welded stainless steel. Search for 'infinity cubes' on YouTube, there's a video on there that takes it from start to finish.
