[Snailed]

I ended up making a Watts link Friday and thought I would show an easy way to make the center link. I used two 3/4" spherical bearings and welded the housings back to back. The rest is just 11g plate and 14g plate I cut out on a bandsaw and welded up. I sized the ends for 5/8" Heims. There is also a .110" spacer between the balls so they don't get bound up when you tighten the 3/4" bolt. You could make this part for about $60.
