Microrax and SES compatibility?

I’m trying to design a small robot, so the small Microrax look tempting. Due to novel actuators, experimentation will be needed, so the ability to put anchor points anywhere along the Microrax will be helpful while testing.

But more information about compatibility between the SES and Microrax parts would be helpful. I don’t know whether the two holes on a Microrax Dual Nut Plate will align with a ASB-19 Servo Horn Bracket… or with any other SES component.

At the moment, I’m interested in making a knee joint between two Microrax ends, using ASB-19 and BBH-01 hub (maybe one joint, maybe two in parallel). But I can’t tell if the parts are compatible.

(Actually, I’d like a much smaller joint, but the selection is limited)

The brackets that can connect directly to the extrusions are listed in the Microrax section. The ASB-19 predates the Microrax system. The hole spacing is not the same as the Microrax.
