RV14 Build August
I did things a little different and did 21-23 before putting on the bottom wing skins. Im really glad I did this and hte access issues to rivet the skin on were minimal. Started in the beginning of the get making the pushrods and priming.
I tired to get smarter this time and made uniques marks on each tube to I would line the correct holes and parts back up after deburring.
Matt helped mark out and drill the aileron push rods. There was a decent amount of work to get the rod ends to fit inside the tubes i.e. some sanding
We put the rod end in the drill and used embry cloth to take it down evenly.
Next I assembled and drilled the torque tubes.
Primed the middle tube after drilling.
Primed the inside of the torque tube collars. I had too much primer in here or on the center tube because the fit after was TIGHT. I didn't realize this was going to be an issue, but installing these later you need the center tube to be able to travel up and down inside the collars to get the assembly installed.
Getting ready to final drill.
Final drilling with the drill press to get a even straight hole for the bolts.
Time to install the push rods. I was lucky and that my measurements where spot on for the long rods.
The shorter aileron push rods proved to be a little off and needed several fittings on and off to get it right. view of the aileron pushrod going through the aft spar.
Mounted the flaps.
Mounted the ailerons and right away on both sides I had an interference issue. I emailed vans and they recommended installing an extra washer as a spacer.
I also noticed the outboard aileron mounting brackets were both bent inward a bit. So a little pressure on these to straighten them out.
Test fitting with the extra washer and the clearance issue is no more!
Installing the pushrod and taking it off and installing it about 10 times to get the correct length. When I went to torque the bolt holding the inboard aileron mount I managed to WAY over do it and strip the threads and spend the next hour getting the bad bolt out and replacing it....Yeah this is fun lol
Using the aileron template to check both pushrods are the correct length. You start with the long one and measure the inboard rod end bearing distance from the rib to check it with the alignment plate in place. For the aileron you check with another alignment plate on the outboard of the aileron.
After getting all the rod ends to a distance that I feel it correct I torqued them to spec.
Okay no more jumping ahead time to rivet on the bottom skin!
