TLDR; don’t bend drag link ends when they are cold. It will break.
Well. I was getting up this morning super excited to get the rest of my 12x30 put together but unfortunately I ran into a snag. The fiber reinforced resin that the drag links are made out of does not like to bend in the cold. My garage is about 38 degrees, so definitely not warm, and when reinstalling the drag link end that is connected to the y-axis it snapped off.
Well poo. I went straight to Amazon to find a replacement and goodness. The ends are the same price as a whole new chain.
I’ll get the new one on Monday and hopefully be up and running.
