Re: [CAD_CAM_EDM_DRO] steel tubing strenght formulas ??

Hi, cant help with the math, but when i found some square tubing, had nice
round corners, and 3/16 wall thick. made a cnc frame, was stiff. went to
find more tubing, found that tubing was custom ordered,,,very expensive to
buy a large lot. so check the tubing and make sure it is a common stocked
tubing. check with a fabricator..cul brian f.
