Rivetted the AN490-HT8P threaded rod end to W-918 aileron tube. The AN470 rivets gave us real headaches, the shop heads continued to shear off on the second pushrod. Really frustrating. Ended up using MSP-42 blind rivets in the four holes instead (used 4 pop-rivets in lieu of the two AN470 rivets). Planning on tack-wlding the pop-rivet parts later on.
