Anti-tab #12

After slaving away at homework all day, I glued the upper skin to the anti-tab this evening.  I still have to glue the skin to the top of the anti-tab spar at another time as I made a mistake when building the tab spar and I didn't account for the taper.  I did this on all of the spars that I have made so far but it shouldn't be a big deal to resolve.

Anti-tab #11

I put the final coat on the internal parts of the anti-tab and upper skin tonight.  Once again, no pictures because it still looks the same.  I played around with clamping methods to see the best way to glue the upper skin on to the rest of the anti-tab.  I tested a machine screw in one of the nut plates to see if the woodscrews and epoxy would hold up to the stress of tightening the machine screw; it passed with flying colors, of course!

Anti-tab #10

I put the second coat of varnish on the internals of the anti-tab and upper skin last night.  It looks pretty much the same as my last post so I didn't take any pictures.

Anti-tab #9

I cleaned up the excess plywood from the edges of the anti-tab lower skin and then I cut a top skin for the anti-tab out of 0.8mm plywood.  Then I traced out the internal structure of the anti-tab so I could know where not to apply varnish.  I put 1 coat of varnish on the top skin and 1 coat on the inside of the assembled anti-tab.

Anti-tab #8

I glued the anti-tab spar to the lower control surface and the ribs last night.  It was a challenge to clamp it together.  I was thinking about this in bed during the wee hours of the morning and I couldn't think of a good reason as to why I didn't glue the ribs to the spar first, then the lower surface, and then the trailing edge; that would have been much easier.

Anti-tab #7

I glued the remaining rib (control horn rib assembly) onto the anti-tab and then used the remaining micro to seal the nut plates on the anti-tab spar.  I haven't been building very much because of school and I have been enjoying learning how to fly the Archer.  I have 5.3 hours in the air so far this month and 0.4 in actual IMC, with my instructor of course.
