I have no idea what Im doing! I dont have any engineering background and I havent worked with metal as Im mostly wood orientated, So I could really use your advise/help.
Im designing a cnc wood router and I would prefer the frame to be made from steel. I need to make a bracket to align the rail but I dont know how to go about cutting a square hole in a rectangular box section of mild steel
Please forgive my attempt at drawing, but It probably better than me trying to explain in words
Any ideas, help, or humorous comments welcome.
I wouldnt use a hammer to put a screw in as I do have some technical ability but could really use some help.
Thanks in advance
