I cut the CS5 and CS12 tubes as per the manual using 1/2'' OD 4130 T5 Steel as stated in a previous post. As the ID of the tube was approximately 0.60'' larger than the male fitting I made barrel nuts to insert into the tbe and give a thread for the male rod ends to screw into. I used 3/8 UNF High Tension steel nuts and machined them to a push fit into the tube and secured them with Loctite 641. I marked the securing bolt holes (Figures show the male ends, the procedure was the same for all the rod ends) as shown in figure 2. I used a 3/32'' dill to make a pilot hole adjusting the job so that the pilot drill was straight as possible. I then drilled the 3/16 hole for the bolt (Ref Figure 3). I deburred the hole, cleaned the area and secured the rod end with the bolt (AN3-10A, AN 960.10/L washers and nut MS21045-3.) as per the builders manual pages 9-7 and 14-9. Once the push rods were completed I cleaned them with Metholated spirits and painted them with Rustoleum primer to prevent corrosion.
