I'm planning to weld together my own motor-driven lift. Can someone help me calculate suitable dimensions for the shaft and pipe? I'm considering buying a mast pipe for the shaft and a 40x40x1.5mm square pipe, which is available at places like Biltema for the "arms." It's also possible to consider reducing the dimension in "B".
You probably need to multiply the force by the lever arm to get the correct torque.
The torque will be M = 300N x 1.36m = 408 Nm.
Are you going to have pipes (A and B) on both sides of the lid, sharing the load equally?
Exactly, a pipe on each side of the lid. I'm having trouble deciding whether to go with regular steel, stainless steel (rf), or aluminum. The latter is tempting as an excuse to buy an AC/DC TIG welder but it would of course be an expensive project. I have a MIG welder for steel and a cheap DC TIG from Jula that I've never used. Steel is the easiest, but rust protection inside the pipes could be an issue.
Ultimately, I want to paint it in anthracite to match the aluminum profiles on my pool cover.
