Thanks for the video. I purchased one, 52" weighing 398KG, also second hand and very rusty, this past Friday, have cleaned about half the rust of so far over the weekend, using steel wool dipped in vinegar, which works really well, and then oiled the parts that had previously rusted. How much does your weigh,? Do you have concerns about it being top heavy? I'm fairly new to metal working so not sure about sizing the metal for the stand to hold 400KG worth of machine, plus some for safety, can you share your thoughts on that maybe? Thanks in advance man.
There are general rules about the strength of tubing, such as: the ticker the wall- the stronger the tube; and the larger the diameter tube, the stronger the tube. For specific calculation of your specific project i would recommend an online calculator, like amesweb.info/StructuralAnalysisBeams/Stresses_Steel_Hollow_Structural_Sections.aspx -OR- www.atlastube.com/axial-load-calculator/ -OR- www.roguefab.com/tube-calculator/
