Used a dowel and scotch brite to clean and prepare the insides of the two tubes for priming. Cleaned it up inside with an acetone wetted cloth pushed through each tube. Taped one end and poured some primer in the other. Blocked that end with a paper towel and rolled the tubes around slowly, tilting them back and forth to fully coat the insides. Propped up to drain surplus primer and sprayed the outsides. Both tubes will be measured and finish cut, now that they have been primed. Finished priming the forward top fuselage skin as well.
From control yoke to elevator bell crank.
Large Elevator tube from bellcrank to rear of plane.
