All I had left to do was attach the control horns and the counterbalance arm and weights and it shouildn't have taken as long as it did.
But the #12 drill is a really snug fit for an AN3 bolt, the grip will fit by the shaft is very tight. Not a big deal on the control horns but the counterbalance arm needed a little bit of filing with the round file to get it the bolt in properly all the way to the seat of the head.
But it got done and now I'm ready to move on to the tail cone.
