No you don't have to send this to ten of your friends. I need to find some info at least, or a model at best, of a chain that is slightly larger than a bicycle chain. I'm designing a tailgate lift and I need to model a manufactureable or commonly available chain. Does anyone have any experience with this and can point me in the right direction? I'm assuming that there are different standard sizes of chain, and if that's the case then pointing me to where I can read up would be great. TIA, Muggs
