I decided to start a new thread on my -7 horizontal Stabilizer mounting efforts. My previous thread talked about my difficulties getting the HS sitting far enough forward to mount properly. That's resolved.
The issue now is triangulation of the HS.
I figured this would apply to many more models than just the -7 so I'm posting it here in the General Forums area.
The plans call for clamping the HS on the aft deck along the fuselage centerline. Then measuring from a common rivet on the HS tip to a common rivet on the firewall. Those numbers should be the same if the HS is perpendicular (square) to the fuselage.
So I have a quick build fuselage and the darn things not square. I was getting a pretty good error when trying to measure to the firewall. The HS was obviously not square when the firewall measurement were the same. So I used the method shown in the Les Bourne Series videos. He uses a rivet in the center of the fuselage for a reference.
When I measure to the fuselage center, all looks well. The HS is only slightly off when viewing the aft deck.
I think the fuselage center rivet is the way to go...I'm just wanting to make sure before I start drilling holes![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
