I have seen the double arms in my internet browsing before, they look a little bit more complicated to make, I am a newbie so I thought I'd stick to the basics. I'll continue making my single arm for now, I'll make a double arm for my next project when I'm a little more experienced.
Any idea on what the radius of my M6 all thread needs to be shaped into? I have 229mm from the center of the hinge pin to the center of my drive bolt. Am I right to just divide that by 2 to get my radius?
Thanks
