Brief Description: Drilled rod end bearing males to control tubes
Each end of the control rods has four holes drilled into them and into the male housing for the rod end bearings. Then you're supposed to draw lines so you can remove the housing and deburr and reinstall them properly.
The problem is the housing fits VERY tightly to the tube and once you drill, it's near impossible to remove them. So I deburred as best I could without removing them (the rattle you hear in one of the tubes is a broken deburring bit)
