Tab Facing Spar #9

I started preparing to mount the control fittings to the tab facing spar last night and I noticed a problem.  The mounting bolts interfere with the hinges.  It appears that there is an issue with the plans in this regard; so, if you are building this airplane, I suggest that you determine a plan of attack before sealing the anti-tab itself.  I am unable to change the locations of the nut plates as the tab is complete.  My option at this point is to move the control fittings into the inboard side of the tab facing spar and cut the two inboard sections from each of the outboard hinges.  It won't be a big deal but I wish that I would have caught it ahead of time so I could have made it work closer to the plans.  I still need to verify the location of the wing ribs on this part of the spar so I am unsure if my solution is 100% acceptable.

Tab Facing Spar #8

I decided to drill the hinge holes in the tab facing spar last night.  The first step was to drill the mounting holes in the hinges 1/64" bigger than I made them originally.  Then I mounted the hinges to the anti-servo tab.  I drew a line on the face of the tab facing spar to locate the bottom of the hinges and then I clamped the tab facing spar to the previously mounted hinges.  Using the hinges as a guide, I drilled the mounting holes in the tab facing spar.

Tab Facing Spar #7

I was doing so well working on this project and then part of the basement flooded so I had to deal with that for a couple of weeks.  I did work a little here and there until today.  I had to go to the pool store which is right next to the airport and being a beautiful day it would have been a wasted trip if I didn't take advantage of the situation.  I noticed about 6 cars in the EAA parking lot so I stopped in to see who was there and what was happening.  Then I logged 0.7 hours solo in the Archer.  I didn't realize it until I filled out my log book but this was my first solo flight in the Archer.  Flying and seeing other members' progress on their planes got me back into the workshop tonight.  I tapered the top and bottom of the tab facing spar and I cleaned the extra plywood from the webs that I glued on previously.  I started to study the rib spacing for the center section of the forward wing and I snapped a few photos for posterity.

Tab Facing Spar #6

I cleaned the extra plywood off the anti-tab skins and trimmed the length of the anti-tab to its finished size.  I glued the webs to the tab facing spar.

I epoxied the top plywood skin on the anti-tab to the top of the anti-tab spar tonight.  Then I cut the inside webs for the tab facing spar.

Idiot Proofing

I notched two of the canard ribs today for attachement of the anti-tab facing spar.  I then cut two of the stub ribs to half height.  The stub ribs hold the plywood sheeting around the anti-tab control horn passageway.  I labeled the top and bottom of all of the canard ribs and the front and back on the two half height stub ribs.
