Turn a roller on the lathe, and drill it for the pull-rod

Final assembly front view.
The roller is adjusted up or down by two nuts on the threaded rod that is welded to the roller holder

Of course, none of this is to scale.
The roller width (not including the two spigots turned on each end) would be a fraction under 1/4", which, combined with the 1/16" plate thickness of the main unit, equates to 3/8" overall width.
The whole unit would have to be folded up with all the components assembled in situ, because there's no way to fit the parts together if the individual components are folded separately

Howdy guys,
The Linkon "Equalizer" adjustable bell crank I posted a pic of ealier in this thread, is for sale $18.00 shipped. Fits a 5/16" sqaure cross shaft. When I bought this from Linkon a few months ago, I was told it was their last one.

It's a well thought out part for sure.
It looks easy enough to duplicate. The hardest part would be to get the right type of swivel/clamp/adjustment wheel. I am wondering if this is a home made part?
Can't find it in my hardware catalogs...
Also, initially the question was to make it for a round 3/8" shaft - I think it was Allan wanting that. Blanton's way has proven itself to work. So, I guess the best of both worlds would be to make them for both round and square shafts
