    Did they come from a chap on here. If so I have a box full. Once your through the first mm that's hardened there beautiful to machine. Near polished finish straight off the lathe.

    I think this is where over engineering is detrimental. Bearings won't last outside, I'd just weld a couple of 20mm bolts (or similar) on the beam and sit them in a couple of 'U' seats (bent strips of steel?) and grease well.

    100 box! for a kids see-saw? Massively over engineered! 50mm tube would do.
    You could end up with a lot of mass there - makes moving the seesaw for a small kid difficult, and once they do, stopping it is going to be as bad - and if the other kid is under the other end when they do . . .

    I'd be happy levering my car in the air with a length of 100 sq 4mm wall box section . . .

    16mm round bar fits nicely inside 21.3mm circular hollow section
    20mm round bar fits nicely inside 26.9mm circular hollow section
