I built a new HS (and elevators) for my -4. I'm leveling up the fuselage in preparation for mounting the HS and have a couple of questions for those that went before me.
I used my laser level to level the top longeron. That went smoothly as shown below. I'm struggling with what reference to use for level in the roll direction.
I pulled the wheels off and tried the axles, but I'm concerned that jacking on the axles individually may put unequal bending loads on the gear which may introduce errors.
After leveling axles, I find one wingtip is about an inch different from the other (relative to the laser level line).
Tomorrow, I will put a spirit level across the cockpit coamings to get a 3rd reference. What is typically used to establish level in the roll direction? (I don't recall what I did when I built the plane 25 years ago...)
Thanks,
