Week 2  This week the main spar for the port lower wing

The bits we received

And what we did with them

This assembly is slightly tricky as the spar is long and thin, and we need to be certain that it stays straight.  First of all I glued one side on, then followed it with the strengthening pieces.  Then I taped it up with masking tape and made sure it was square.  Then I left it to dry for a few hours.  You'll note that I didn't measure the position of the strengthening pieces.  As they are hidden from view I didn't see much point.  Just make sure they don't foul any of the cutouts.  (I really hope I don't live to regret this.  The only thing which may screw things up is if we have to start drilling holes in the spar, but I don't think this is going to happen.

When it was dry I un-taped it and glued the other side in place and taped that up.  I noticed that the spar had taken on a slight twist, so I placed some weights on it to hold it flat while the glue dries.

The weights did their job.  The final task of adding the tops to the spar was very simple.  Note that I also used a couple of scraps of wood for the notches near the wing tip.

Hot tip of the week

Keep it flat and square.  This is really important if you want your model to look good.
