I don¡¯t know that one style bearing is better than the other. This is a low speed operation that isn¡¯t really meant for either type of bearing. Did either one sag less than the other? Kind of hard to quantify that with one being wood the other being metal. So just go with whatever is easiest and simplest to do.

The knuckle using wood is wider than what Randy made with aluminum. ?I did not yet see how the hose would work with the wood version yet. ?That is next as I will make "real" arms with pipe and hose now that I have the knuckle worked out. ?In addition to the wood version having a wider knuckle, I extended the top and bottom pieces out farther and that gives more room for the hose. ?In Randy's version if you will note, the gears are cut. ?I was planning to not only have the arms back a bit farther on the extensions that attach to the top plates, but also notch out a little on 1 side of each arm (as shown in the black lines) so the flex hose can be a bit longer so that ?the flex and compression will not be over such a short distance. ?Once I try that out, I will see if I need wider top-bottom plates.
Any thoughts from anyone on the 2 options for the bearings?
