Main Wing Spar

Here is the main wing spars. Nice and golden Anodized.

 

This how I supported the wing spars upright.

 

Me drilling and countersinking the Spars to attach the Tank nutplates.

If you are interested I did a nice write-up how to make this process easier over here:

 

Here a picture with all the holes countersunk.

 

A close up of the countersunk holes, you can see the edge still needs to be deburred.

 

A picture showing all the nutlpates installed on the wing spar flanges.   

 

A view of the nutplates from the other side....

 

 

Next on the list was to manufacture and drill the tie down bracket assembly.

 

The tie down clecko'ed and the spar used to back drill the holes

 

This is what the tie down assembly looks ready just before assembly, it will need to get primered before the actual assembly.

 

Then I primed and riveted the tie-downs together
