## Notes

- Aluminum square tube in 6063-T52 (specification AMS-QQ-A-200/9 as listed), the extruded 'structural' hobby and fixture tube sold by McMaster-Carr, Online Metals and Metals Depot. Wall thickness 0.062 in is the nominal 1/16 in (1.5748 mm) and 0.125 in is 1/8 in; the distributor prints 0.062, not 0.0625.
- Corner radius: the distributor listing (Continental Steel) states 'sharp inside and outside corners', so the files are hollow rectangles with square corners. ABC Supply's catalogue also lists radius-corner variants (for example 1 x 2 x .062 with a .140 R, 2 x 4 x .250 with .375 R), each one a separate item, so there is no standard radius to draw; if your tube has rounded corners, measure it.
- Files: 17 sizes drawn as 4 in (101.6 mm) long extrusions along X, centred on y = 0, z = 0 on the bottom face. Weights are as printed. A check on every file: the printed kg/m divided by the drawn section area gives 2.68 to 2.69 g/cm3, aluminum density.
- Nominal dimensions only: Aluminum Association tolerances on size, wall and straightness are not applied. The published sizes are the stock sizes of one distributor, not a closed standard list; other mills sell more.
- McMaster-Carr has the aluminum tube per-part STEP files (linked, not copied).
