It seems we're getting into a rhythm now on how I'm going to post. The amount of information I post, or how many steps I cover is pretty much limited to the number of pictures I can post at once. I can only post 12 pictures at a time, so each construction post I make is going to be limited to how many pictures I can post that support the text in each post. One thing I wanted to do from the start of this build thread is to make sure there are pictures of everything that I do on the build. The old saying “A picture is worth a thousand words” really is true. So I hope that I'm letting everybody have plenty of chances to see what is going on. Like I said in one of the first posts, if there is something that you don't see in the pictures I post please let me know and I'll see if I can't get a picture for you. Trust me, I have tons of pictures that aren't getting posted in this thread.

After laying down the rear spar the next step is going to be another piece of sheeting (WS-B3) that spans between the rear spar and the trailing edge. When we get to the trailing edge there is a huge note that should be read and understood, otherwise there could be a lot of confusion about what is going on with the build. The trailing edge is already notched for you to place each rib in. These notches are the gospel of where the ribs are placed. And this is what the note tells you. If the notches in the trailing edge don't match up with the plans, then you should use the notches on the trailing edge as your guide to placing the ribs in the wing. The plans tell you that it's possible for the plans to shrink or expand and that could cause the notches to not match the trailing edge. While this is true, it's also possible that you don't have to plans completely flat and stretched out when you pinned them down. If the plans are WAY off (not just a little bit) you might want to consider repositioning the plans on your building board. If so, carefully pull the pins out holding down your work up to this point. Once your work is free move it out of the way. Remove your plan protector and remove the tape holding the plans down. To reposition the plans tape down one side and use your hand to smooth out and stretch out the plans moving away from the edge that you have taped down. You can double check against the trailing edge while you stretch. You might be surprised just how much the plans were off. Once you have it close you need to get everything back on the board. Replace you plan protector. Carefully re-pin your work to the board, a making sure it's all in the correct position as it goes back down, and that the spars are once again straight.

Before I put down the trailing edge, I need to to lay down the next piece of sheeting which goes between the rear spar and the trailing edge. Putting in the piece of sheeting is just like that last one that I put down. I put a bead of glue on the sheeting and glued it to the rear spar. Just like before you'll want to make sure it's all weighted down it's flush with the bottom of the rear spar. You don't have to wait for this glue to set before you move on to the trailing edge. That is one thing I like about working with wood glue, I've got about 30 minutes before the glue sets, so I can put several items on and then wait for them all to set. As the instructions said, I placed the trailing edge down lined up on the inside edge of the wing as my guide. After repositioning the plans the notches matched up a lot better than before (And you only thought I was giving advice, but it never happens to me. Nope nope nope . That really happened, that's why I knew about repositioning the plans!!! ). Once I know where the trailing edge will sit I applied the glue to attach it to the sheeting in place, WS-B3. As with the main and rear spar this trailing edge will keep the wing straight, so it's important to secure the trailing edge accurately to the plans. It's also important to make sure that the trailing edge sits flat on the building board. To get an idea of how it should sit I dry fit a rib on the plans. The bottom of the rib should sit flat with the building board, the end of the rib should be firmly seated in the the notch of the trailing edge, and the top and bottom of the rib should be flush with the top and bottom of the trailing edge. Once the trailing edge is positioned on the plans where it should be, and the bottom of the trailing edge is flat on the building board I went ahead and secured the TE on the board. I made sure that it was straight all the way across the wing.

This looks like a good place to stop. I'm going to let all of this sit and make sure the glue is set, and then I'll start placing the ribs this evening.
